Prevalence, structure and clinical significance of conduction disturbances was studied according to the electrocardiography findings in 1189 older pilots in aged 55 years and older, who were to the Central Civil Aviation Hospital (Moscow) and examined on the regular bases. Resting electrocardiogram was recorded in all subjects according to generally accepted methods. Heart conduction disorders were detected in 16,9% of pilots of the older age group. More common were intraventricular conduction disturbances - 13,7% of cases, atrioventricular conduction disturbances were recorded less often- 1,8% of cases, and their combination was even less common - 0,6% of cases. Cardiac conduction abnormalities as part of another electrocardiogram syndromes were noted in 10 (0,8%) peoples. Older civil aviation pilots are characterized a lower frequency of electrocardiogram changes compared to a general population of the same age in the Russian Federation. The signs of cardiac conduction disturbances on the electrocardiogram in civil aviation pilots did not always lead to unfitness to fly. The evaluation of fitness to flight in some electrocardiogram deviations is depend of the presence or absence of cardiovascular disease, functional condition of the cardiovascular system and the data of additional examination methods. Diagnosis of heart rhythm and conduction disorders is important in assessing the state of the circulatory system, especially in flight personnel. Timely detection of cardiac conduction disorders in civil aviation pilots is essential for maintaining medical safety, especially in older people. Electrocardiography is performed as an initial method for assessing the state of the conducting heart system in civil aviation pilots.

Abstract. Prevalence and clinical significance of electrocardiography findings was studied in 1189 older pilots in aged 55 years and older, who were consistently admitted to the Central Civil Aviation Hospital (Moscow) and examined on the regular bases. Resting 12-lead electrocardiogram was recorded in all subjects according to generally accepted methods. Normal electrocardiogram was found in 78,5% of older pilots. None of the examined showed signs of myocardial infarction. Minor electrocardiogram abnormalities was registered in 21,5% of pilots. Cardiac conduction disorders were predominated 16,1% of cases, most of them were intraventricular conduction disorders 13,7% of cases. Another electrocardiogram abnormalities were less common 4% of cases. Mixed electrocardiogram abnormalities were noted in a small number of observations in 1,4% of individuals. Thus, older civil aviation pilots are characterized a lower frequency of majority electrocardiogram deviations compared to a population of the same age. The evaluation of fitness to flight in some electrocardiogram deviations is depend of the presence or absence of cardiovascular disease, functional condition of the cardiovascular system and the data of additional examination methods. On the whole, the electrocardiogram use as a screening in asymptomatic individuals has some significant limitations - a number of detected abnormalities may be normal variants, as well as a normal electrocardiogram may be in significant narrowing of the coronary artery. Nevertheless, the need for electrocardiogram recording is recognized by aeromedical specialists of different countries, since this method is exclude a number of pathological changes, which are significant for flight safety.

As a rule, heart damage in patients with sarcoidosis of respiratory organs (SOD) is not diagnosed in time, so a very important and urgent task is to identify common heart rhythm and conduction disorders.The aim of the study was to investigate the main clinical manifestations of sarcoidosis in SOD, depending on the peculiarities of the disease course and to compare the frequency and severity of pulmonary and extrapulmonary manifestations of sarcoidosis, including myocardial lesions and electrocardiographic (ECG) signs of heart rhythm disorders.Methods. In the period 2006– 2016, the pilot open prospective uncontrolled study conducted at the Pulmonology Department of the Regional State Autonomous Healthcare Institution "Tomsk Regional Clinical Hospital" included patients (n = 84) aged 20–67 years with the diagnosis of SOD. Patients were divided into 2 clinical groups: the 1st comprised 45 (53.5%) patients with a favorable course of sarcoidosis, the second one included 39 (46.4%) patients with an unfavorable course of the disease. A full range of studies was carried out, including the analysis of medical history and clinical and epidemiological data, instrumental methods (including ECG and Holter ECG monitoring (HM), pathomorphological study of lung biopsy samples.Results. According to the data of frequency analysis of occurrence of pulmonary and extrapulmonary clinical manifestations in ODS, it was shown that the leading clinical manifestations, most frequently occurring in patients of both groups, included asthenia syndrome (72.6%), bronchial syndrome (66.7%) and fever syndrome (33%). In 33% of cases, clinical manifestations of myocardial damage were detected. In 41 (51.2%) patients in both groups, changes on ECG were recorded at rest. Regardless of the course of the disease, in 23.5% of patients of both clinical groups, according to the results of the HM ECG, rhythm and conduction disturbances were found – a combination of ventricular arrhythmias and conduction disorders (ventricular extrasystole and right His bundle branch block of various degrees) and a combination of supraventricular arrhythmias and conduction disturbances (supraventricular extrasystole and right His bundle branch block of various degrees).Conclusion. Thus, regardless of the severity of the disease course, SOD patients are concerned about complaints from both respiratory system and extrapulmonary manifestations, including cardiac complaints, as well as heart rhythm and conduction disorders (according to the results of ECG and HM ECG), the frequency of which, according to the comparative analysis, has not significantly changed in both clinical groups, which indicates the non-specific character of clinical manifestations.

Overall Mortality

A retrospective study on arrhythmias and conduction disturbances was conducted in 1986 in the Division of Pediatric Cardiology of Dr. Pirngadi Hospital, Medon. There were 106 (35.33%) cases with arrhythmias and conduction disturbances out of 300 patients studied. The most common type of arrhytmia among the patients under 5 was intraventricular conduction defects, whilst in the age group of 5-10 were sinus tachycardia and intraventricular conduction defects, and in the age group of 10-15 was first degree A-V block.Rheumatic heart diseases and VSD were the most common cardiac diseases associated with arrhythmias, where the frequency were 18.86% and 10.37%, respectively. Arrhythmias associated with several extracardiac diseases were found in 60 (56.61%). Two out of 7 cases who was rreated with antia"hythmic agents died with SVT associated with bronchopneumonia, and atria/fibrillation associated with gastroenteritis, dehydration and malnutrition. Treatment against the main diseases (without antiarrhythmic agents) was done in the remainders. Even though the overall mortality rate was 13.20%, it was not due to arrhythmia itself but most of them died of non-arrhythmic origin.

The aim of the study was to compare the state of psychophysiological functions of highly qualified handball players with different experience of sports training (special training). To determine the state of psychophysiological functions of athletes diagnostic complex "Diagnostics-1" was used (MV Makarenko, VS Lyzogub). In accordance with the purpose of the work, we studied the properties of the nervous system (functional mobility and strength of nervous processes), the efficiency of sensorimotor activity and the dynamics of nervous processes in feedback, the latency of complex response reactions of choice, the accuracy of response to a moving object. Higher psychophysiological status in terms of the strength of nervous processes (both in the feedback mode and during long-term sensorimotor loads in the mode of imposed rhythm) was demonstrated by athletes of the older age group with more experience of sports training. Athletes of older and younger age groups did not differ in the level of functional mobility of nervous processes and accuracy of reaction to a moving object. Therefore, we can assume that athletes with less experience of sports training in the state of these psychophysiological functions have reached the level of athletes of the older age group, ie the level of maximum realization of individual capabilities. The identified differences in the individual-typological properties of the higher parts of the central nervous system in female handball players with different sports experience can have prognostic value and be used to optimize sports improvement in this sport.

The structural- functional changes of heart chambers (changes in size, volume, shape and function of the heart) are the basis of the cardiac remodeling — an important element of the cardiovascular continuum, which is a key mechanism for the progression of the main cardiovascular diseases. Echocardiography is the main and available method for its assessment.Material and methods. 1189 civil aviation pilots aged 54–68 who underwent routine in-patient examination at the Central Clinical Hospital of Civil Aviation were examined on a regular basis with further medical assessment at the Central Medical Flight Expert Commission of Civil Aviation of the Russian Federation in 2009–2010. The average age was 56.75 ± 0.07. Transthoracic echocardiography was performed for evaluation of the structural-functional indicators of the cardiovascular system in 1170 of flight personnel (98.4%).Results. Enlarged size of the heart chambers was minor and moderate without heart failure and was detected in 4.8% of civil aviation pilots of senior age group. Abnormal geometry of left ventricular (LV) was revealed in 61.7% of the examined civil aviation pilots of senior age group: left ventricular hypertrophy (LVH) — in 1% of pilots (concentric LVH — 0.6 % and eccentric LVH — 0.4% cases), concentric remodeling of the LV — in 60.7% pilots. The decrease in LV ejection fraction was observed only in one pilot with EF— 53%. Pilots inapt for flying had enlarged chambers more often than pilots with fitness to fly (9.8% vs 3.35% pilots; p < 0,0001) and LVH (2.9% vs 0.45%; p < 0,001).Conclusions. Echocardiography is an important method for cardiac chambers evaluation, including determination of type LVH geometry. It can be used in the medical assessment of civil aviation pilots of the senior age group.

Aim. To study the prevalence of ECG changes associated with gender and age according to the program ESSE-RF, Kemerovo.Material and methods. The object of the study is a random sampling of male and female population aged 25-64, Kemerovo. The standard 12-leads ECG was captured in 1623 people. Coding was carried out according to the Minnesota code. The average age of the respondents was 49 years (37; 57), men, 47 years (36; 56), women, 50 years (38; 57), (p=0,004).Results. The ECGs changes were recorded in 265 people (16,3%), in 124 men (17,8%) and 141 women (15,2%) (p=0,159). Heart rhythm disturbances were revealed in 108 people (6,7%), intraventricular conduction disturbances in 147 (9%). The most frequently recorded changes in the T wave (in 11,2% of the subjects), ST segment changes take the second place (in 5,1%), the pathological Q wave was registered less frequently (in 2,5%). In men, the ECG signs of LV hypertrophy, rhythm disturbances, the pathological Q wave were more often detected. In the group of the 50-64-year-olds, the pathological Q wave, changes in ST segment and T wave, rhythm and conduction disturbances were detected significantly more often as well as the greater prevalence of risk factors of ischemic heart disease.Conclusion. Detection of ECG changes is an important stage in the formation of a risk group at the development and progression of the cardiovascular pathology.

Abstract Introduction Restrictive cardiomyopathy (RCMP) is characterized by restrictive filling and reduced diastolic volume of either or both ventricles with normal or near-normal systolic function and wall thickness. It may occur idiopathically or as a cardiac manifestation of systemic diseases and various neuromuscular disorders. Often RCMP occurs with severe symptoms of heart failure and has an poor prognosis. Given the presence of structural myocardial abnormalities, atrial dilatation, this group of patients has a high risk of heart rhythm and conduction disturbances. Objective To present our clinical experience in RCMP with the heart rhythm and conduction disturbances in children. Material and methods The study was approved by the Institute Ethical Review Board. On behalf of the children enrolled in the study, written informed consent was obtained from the next of kin. The study included 18 children with RCMP presented with heart failure class II-IV. The genotyping was performed to all patients. The identified genetic variants were classified according to ACMG guidelines. We analyzed clinical history, data of physical examination, laboratory findings, ECG, echocardiography, Holter monitoring, genetic test, cardiac MRI and CT performed according to clinical indications and physician's. Results Mean age of RCMP manifestation was 2,1 y.o. [0–11] with HF as a main clinical feature. Rhythm and conduction disorders were reported in 83% (n=15) of children. The structure of the disorders included: atriventricular block 1–2 degrees in 22% (n=4), supraventricular disorders (extrasystole, tachycardia, atrial fibrillation) in 44% (n=8), ventricular disorders (extrasystole, tachycardia) in 16% of patients (n=3). One patient had a combined rhythm and conduction disorder (sinus sick syndrome, atrial fibrillation, supraventricular and ventricular tachycardia), which required implantation of a pacemaker with a defibrillator function. In one patient, the manifestation of the disease was with hemodynamically significant permanent-recurrent atrial tachycardia. Mortality in this group of patients was 27% (= 5), the cause of death was the progression of heart failure in 3 children and sudden arrhythmial death in 2 patients. Conclusions Thus, RCMP is a severe, genetically caused, with early manifestation progressive disease with high risks of rhythm and conduction disturbances, sudden arrhythmial death. According to the testimony, patients should receive antiarrhythmic therapy and, if necessary, pacemaker implantation is indicated.

Aim.To study the effectiveness of prolonged use of PAP therapy (positive airway pressure therapy) in eliminating sleep respiratory disorders and associated cardiac conduction disturbances. Materials and methods.We included 21 patients who were examined at the Myasnikov Institute of Clinical Cardiology, National Medical Research Center of Cardiology, regarding cardiac rhythm and conduction disturbances, as well as obstructive sleep apnea and who have been on PAP therapy for more than 12 months. The average age was 66.5 [63.5; 73.2] years, body mass index 33.0 [30.2; 38.5] kg/m2, apnea-hypopnea index 65.0 [59.0; 86.3]/h. At the time of analysis, 15 patients continued to use PAP therapy (mean time of use: 6.0 years [4.7; 9.2]) and 6 patients refused long-term use of PAP therapy, mean time to use PAP therapy until failure amounted to 2.82.1 years. Results.PAP therapy lead to a persistent decrease in apnea-hypopnea index of 63.6/h to 3.7/h was (p=0.0002). 86% of patients met the criteria for adherence to PAP therapy (use 4 hours/night, more than 70% of nights). Initially, before the use of PAP therapy, all cardiac conduction disorders were during sleep and exceeded 3 seconds, with fluctuations from 3.1 to 10.6 seconds. PAP therapy appeared to be effective in all patients: no asystoles, duration of more than 3 seconds, were detected. Conclusion.In obstructive sleep apnea patients with concomitant nighttime cardiac conduction disturbances, the long-term use of PAP therapy is effective and with good adherence.

This review discusses the role of autoimmune mechanisms in the development of heart rhythm disturbances and conduction disorders of various origins. The search was performed using PubMed, Medline and Google Scholar. Specific cardiovascular diseases (dilated cardiomyopathy, myocarditis, conduction disorders) developing in childhood and adolescence are associated with an increase in titer to intracellular proteins specific to myocardiocytes and cells of the cardiac conduction system. Candidate autoantibodies markers for autoimmune response have been selected. The rationale for analyzing the immune status of heart rhythm disturbances in children and adolescents has been provided.
