Genetics of cardiac arrhythmias [PDF]
Over the last decade, we have witnessed a revolution in the understanding of primary cardiac arrhythmia syndromes. These remarkable advances stemmed from the discovery of mutations, primarily in ion channel genes, underlying a number of these disorders.

Stress-Induced Cardiomyopathy Secondary to COVID-19
A 67-year-old female with prior medical history of HTN and asthma presented with acute-onset dyspnea and nausea for 4 days prior to admission. Upon initial encounter in the emergency room, she was found to have findings of abnormal pulmonary infiltrates ...

Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Stress and Cardiac Arrhythmias
Stress can exert adverse effect on cardiovascular health. Psychosocial stress adversely affects the autonomic homeostasis. This in turn can result in metabolic abnormalities, inflammation and dysfunction of endothelium. Changes in the autonomic homeostasis can be a major trigger for ventricular tachyarrhythmias].

The main inherited cardiac arrhythmias are long QT syndrome, short QT syndrome, catecholaminergic polymorphic ventricular tachycardia and Brugada syndrome. These rare diseases are often the underlying cause of sudden cardiac death in young individuals and result from mutations in several genes encoding ion channels or proteins involved in their ...

Bidirectional ventricular tachycardia in cardiac sarcoidosis. [PDF]
A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor.
