Catecholaminergic polymorphic ventricular tachycardia


Tell me about catecholaminergic polymorphic ventricular tachycardia.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a genetic heart condition characterized by an abnormally fast and irregular heartbeat triggered by physical activity or emotional stress. The heart has 4 chambers: the atria (upper chambers) and the ventricles (lower chambers). Individuals with CPVT experience a rapid, irregular heartbeat from the ventricles, called ventricular tachycardia. Because the heart is beating fast, it does not have enough time to fill completely, resulting in lower volumes of blood being pumped throughout the body. This can cause lightheadedness, fainting episodes, and sudden cardiac death.

Individuals with this condition can have episodes starting in childhood. If undiagnosed, CPVT can lead to sudden cardiac death in children or young adults.
