CARDIAC ARRHYTHMIAS CAN BE found in the fetus and the neonate. Arrhythmias that are seen in the neonate include sinus bradycardia and tachycardia, premature atrial and ventricular contractions, supraventricular tachycardia, atrial flutter, ventricular arrhythmias, and heart block. Although infants with structural or functional anomalies can have arrhythmias, many arrhythmias result from noncardiac causes, such as hypoxemia and acidosis.1

Cardiac arrhythmias often present to family physicians with diverse clinical manifestations. This retrospective observational study was carried out in a private cardiology clinic in Dhaka from July 2004 to December 2008. A total of 1257 patients were referred from family physicians in the locality. 75 (5.96%) patients were diagnosed as having cardiac arrhythmia by ECG. Various types of atrial arrhythmias are more common than ventricular arrhythmias (60% vs 40%). Atrial fibrillation (N=18) and PVC (N=17) are the 2 commonest arrhythmias found in this study. This study identifies the clinical presentation, possible aetiology and management of patients having cardiac arrhythmias. Palpitation (46.66%) and asymptomatic ECG changes (34.66%) were the 2 most common reasons for referral. Most of the patients could be managed on a out-patient basis. Most arrhythmias like 1st degree heart block, PAC & isolated PVC, RBBB, Sinus bradycardia were asymptomatic & did not need any further treatment except assurance & anxiolytics. Other arrhythmias like atrial fibrillation, LBBB, bifascicular or advanced heart block, SSS & SVT needed further evaluation. This article particularly focuses on the general approach of family physicians while dealing with patients with cardiac arrhythmias.

Cardiac arrhythmias are common in hospitalized patients, with their incidence increasing in older patients and those with comorbidities. Cardiac arrhythmias represent a trigger for approximately 10% of rapid response team (RRT) activations. Of those, atrial fibrillation (AF) is the most commonly observed. Other common cardiac arrhythmias in the in-hospital setting include supraventricular tachycardia, atrial flutter, ventricular tachycardia, and bradycardias. Members of the RRT should be skilled in the diagnosis and management of these common arrhythmias. This chapter presents an overview of cardiac arrhythmias that RRT members are likely to encounter, discussing their incidence and significance, as well as their immediate management.

Qt Interval Prolongation

Hypoglycaemia can cause cardiac arrhythmias such as QT interval prolongation and ventricular arrhythmias. Supraventricular arrhythmias and sinus bradycardia were rarely reported. We present the clinical case of an 84- year-old man who developed a persistent bradycardia after a hypoglycaemic episode. After restoration of normoglycaemia, bradycardia persisted for almost eighteen hours, without QT prolongation or any symptoms. Hypoglycaemia is an unusual cause of bradyarrhytmias mainly mediated by neurologic and endocrine systems. Our clinical case supports recent recommendations for more relaxed inpatient glycaemic targets in frail older adults who may be particularly vulnerable to hypoglycaemia and its consequences.

Background - COVID-19 has led to over 1 million deaths worldwide and has been associated with cardiac complications including cardiac arrhythmias. The incidence and pathophysiology of these manifestations remain elusive. In this worldwide survey of patients hospitalized with COVID-19 who developed cardiac arrhythmias, we describe clinical characteristics associated with various arrhythmias, as well as global differences in modulations of routine electrophysiology practice during the pandemic. Methods - We conducted a retrospective analysis of patients hospitalized with COVID-19 infection worldwide with and without incident cardiac arrhythmias. Patients with documented atrial fibrillation (AF), atrial flutter (AFL), supraventricular tachycardia (SVT), non-sustained or sustained ventricular tachycardia (VT), ventricular fibrillation (VF), atrioventricular block (AVB), or marked sinus bradycardia (HR<40bpm) were classified as having arrhythmia. De-identified data was provided by each institution and analyzed. Results - Data was collected for 4,526 patients across 4 continents and 12 countries, 827 of whom had an arrhythmia. Cardiac comorbidities were common in patients with arrhythmia: 69% had hypertension, 42% diabetes mellitus, 30% had heart failure and 24% coronary artery disease. Most had no prior history of arrhythmia. Of those who did develop an arrhythmia, the majority (81.8%) developed atrial arrhythmias, 20.7% developed ventricular arrhythmias, and 22.6% had bradyarrhythmia. Regional differences suggested a lower incidence of AF in Asia compared to other continents (34% vs. 63%). Most patients in in North America and Europe received hydroxychloroquine, though the frequency of hydroxychloroquine therapy was constant across arrhythmia types. Forty-three percent of patients who developed arrhythmia were mechanically ventilated and 51% survived to hospital discharge. Many institutions reported drastic decreases in electrophysiology procedures performed. Conclusions - Cardiac arrhythmias are common and associated with high morbidity and mortality among patients hospitalized with COVID-19 infection. There were significant regional variations in the types of arrhythmias and treatment approaches.

Supraventricular Tachycardias

Supraventricular tachycardias (SVTs) comprise a group of usually benign arrhythmias that originate from cardiac tissue at or above the His bundle. SVTs include inappropriate sinus tachycardia, atrial tachycardias (ATs), atrial flutter (AFL), junctional tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT), and forms of accessory pathway–mediated reentrant tachycardias (atrioventricular reentrant tachycardia [AVRT]). Although mostly benign, symptoms can be debilitating, in the form of palpitations, shortness of breath, chest discomfort, dizziness, and/or syncope; rarely, SVTs can result in cardiomyopathy due to incessant arrhythmia. This review covers the epidemiology, diagnosis, management, and classification of SVTs.  This review contains 14 figures, 17 tables, and 61 references.
