CARDIAC OUTCOMES DURING PREGNANT AND NON-PREGNANT PERIODS IN CATECHOLAMINERGIC POLYMORPHIC VENTRICULAR TACHYCARDIA

摘要

BACKGROUND: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited heart rhythm disorder characterized by life-threatening arrhythmias during exertion or emotional stress. Ventricular arrhythmias are typically adrenergically-driven, and may be associated with syncope and sudden cardiac death. Pregnancy is associated with various cardiovascular changes that may influence the frequency of arrhythmic events in CPVT. Little is known about the arrhythmic risk during pregnancy.
