…or any other activity causing adrenergic stimulation, increase the risk of syncope, ventricular arrhythmias and sudden cardiac arrest. ARVC can cause ventricular tachycardia, ventricular fibrillation…

…30 premature ventricular contractions occur consecutively, it is referred to as non sustained ventricular tachycardia (if the rate is 100 beats/min) or ventricular rhythm…

…and anxiety. As the tachyarrhythmia originates above the ventricles, ventricular depolarization proceeds normally via the His Purkinje system, and in most cases, there is no…

…When the ventricular rate remains below this threshold, the arrhythmia is classified instead as an ectopic atrial rhythm (EAR) . Ectopic atrial tachycardia (EAT) most commonly…
