Catecholaminergic Polymorphic VT: Definition, Clinical Significance, and Overview
Catecholaminergic Polymorphic VT is an inherited arrhythmia syndrome that causes abnormal fast heart rhythms from the ventricles during adrenergic stress. It is a cardiac electrophysiology disorder rather than a structural heart disease. It is most commonly discussed in syncope evaluation, exercise-related palpitations, and sudden cardiac death risk assessment. It is frequently encountered in pediatric and young adult cardiology, emergency care, and inherited arrhythmia clinics.
