Life-threatening ventricular tachycardia

Life-threatening ventricular tachycardia is a high-acuity cardiovascular arrhythmia originating within the ventricular myocardium or His-Purkinje conduction system

Life-threatening ventricular tachycardia is a high-acuity cardiovascular arrhythmia originating within the ventricular myocardium or His-Purkinje conduction system It is pathologically characterized by three or more consecutive premature ventricular depolarizations at rates typically exceeding 100 beats per minute, commonly driven by myocardial reentry circuits, abnormal automaticity, or triggered activity related to structural heart disease or ischemic scarring

It is pathologically characterized by three or more consecutive premature ventricular depolarizations at rates typically exceeding 100 beats per minute, commonly driven by myocardial reentry circuits, abnormal automaticity, or triggered activity related to structural heart disease or ischemic scarring The rapid rate critically compromises ventricular filling, stroke volume, and systemic perfusion, manifesting as profound hemodynamic instability, syncope, hypotension, or acute cardiogenic collaps...

Primarily affecting patients with ischemic cardiomyopathy, structural heart abnormalities, or cardiac channelopathies, this clinical state carries an immediate risk of precipitating cardiac arrest and sudden cardiac death via degeneration into ventricular fibrillation
