Introduction: Although rare, iatrogenic cases of pneumopericardium have been documented following laparoscopic surgery and mechanical ventilation. Electrocardiogram (ECG) changes, including ST-segment depressions and T-wave inversions, have been documented in cases of pneumopericardium, and can mimic more concerning causes of chest pain including myocardial ischemia or pulmonary embolism. Case Report: This unique case describes a patient who presented with chest pain and ST-segment changes on ECG hours after a laparoscopic inguinal hernia repair and who was found to have pneumopericardium. Conclusion: While iatrogenic pneumopericardium is often self-limiting and rarely requires intervention, it is critical to differentiate pneumopericardium from other etiologies of chest pain, including myocardial ischemia and pulmonary embolism, to prevent unnecessary intervention.

Introduction. Acute myocardial infarction is a clinical manifestation of coronary disease which occurs when a blood vessel is narrowed or occluded in such a way that it leads to irreversible myocardial ischemia. ST segment depression in leads V1?V3 on the electrocardiogram points to the anterior wall ischemia, although it is actually ST elevation with posterior wall myocardial infarction. In the absence of clear ST segment elevation, it may be overlooked, leading to different therapeutic algorithms which could significantly affect the outcome. Case report. A 77 year-old female patient was admitted to the Coronary Care Unit due to prolonged chest pain followed by nausea and horizontal ST segment depression on the electrocardiogram in V1?V3 up to 3 mm. ST segment elevation myocardial infarction of the posterior wall was diagnosed, associated with the development of initial cardiogenic shock and ischemic mitral regurgitation. An emergency coronarography was performed as well as primary percutaneous coronary intervention with stent placement in the circumflex artery, the infarct-related artery. Due to a multi-vessel disease, surgical myocardial revascularization was indicated. Conclusion. Posterior wall transmural myocardial infarction is the most common misdiagnosis in the 12 lead electrocardiogram reading. Routine use of additional posterior (lateral) leads in all patients with chest pain has no diagnostic or therapeutic benefits, but it is indicated when posterior or lateral wall infarction is suspected. The use of posterior leads increases the number of diagnosed ST segment elevation myocardial infarctions contributing to better risk assessment, prognosis and survival due to reperfusion therapy.

Out of 284 patients admitted to the Coronary-Care Unit, 60 patients showed an acute monophasic injury pattern (M-Complex) on their initial electrocardiogram (ECG). There were 13 fatalities on the first day of myocardial infarction; 6 from the M-complex group. Three of these 6 patients died with cardiac rupture. The ECG features of these 3 patients were compared with the 3 non-rupture patients. A progressive increase in the elevated R-ST segment of the M-complex with an upward ‘pull’ of the R-ST junction, proved to be an ominous ECG sign of impending cardiac rupture in patients with protracted chest pain and persistent hypertenison. The 3 non-rupture patients remained in a hypotensive state from admission to the time of death. Atrioventricular block and A-V junctional tachycardia were the commonest rhythm disturbances in patients dying with cardiac rupture.

Abstract: The veterinary cardiology has growing importance in equine medicine. There are studies of standardization of electrocardiographic parameters of many races, according to their stature and ability. However, no studies are in the literature with the American Miniature Horse. To evaluate the electrocardiogram (ECG) tracing configuration of this breed at rest and to verify the influence of age and sex on ECG parameters, 203 horses including 143 females and 60 males were divided into four age groups (foals, yearlings, adults and elderly). Electrocardiographic parameters were performed by computerized electrocardiogram (TEB), and the parameters were evaluated in six leads of frontal plane (Lead I, II, III, aVR, aVL and aVF) and base-apex (BA). Heart rates (HR) decreased with increasing age were higher in males than in females. Sinus tachycardia followed by sinus arrhythmia was dominant in both sexes. The cardiac axis was higher in males and ranged between 120° and 150° for foals, 30° and 60° for yearlings and adults, and 60° and 90° for the elderly. The P wave was bifid in several animals. The P-wave amplitude and T-wave duration from lead II and BA were larger in males than in females. The majority of the animals exhibited ST segment depression and a negative T-wave. The most common QRS complex morphology was Qr. Differences were observed between the electrocardiographic tracings of males and females, and age influenced the ECG parameters. Therefore, this study established the ECG patterns for the American Miniature Horse breed and could be used to determine the influence of age and sex on several of the studied variables.

Background.Computerized electrocardiogram (ECG) analysis has been of tremendous help for noncardiologists, but can we rely on it? The importance of ST depression and T wave inversions in lead aVL has not been emphasized and not well recognized across all specialties.Objective.This study’s goal was to analyze if there is a discrepancy of interpretation by physicians from different specialties and a computer-generated ECG reading in regard to a TWI in lead aVL.Methods.In this multidisciplinary prospective study, a single ECG with isolated TWI in lead aVL that was interpreted by the computer as normal was given to all participants to interpret in writing. The readings by all physicians were compared by level of education and by specialty to one another and to the computer interpretation.Results.A total of 191 physicians participated in the study. Of the 191 physicians 48 (25.1%) identified and 143 (74.9%) did not identify the isolated TWI in lead aVL.Conclusion.Our study demonstrated that 74.9% did not recognize the abnormality. New and subtle ECG findings should be emphasized in their training so as not to miss significant findings that could cause morbidity and mortality.
