Catecholaminergic polymorphic ventricular tachycardia

Overview

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.

What type of disease is catecholaminergic polymorphic ventricular tachycardia?

Catecholaminergic polymorphic ventricular tachycardia is considered to be a cardiac genetic disease. Symptoms of this condition primarily affect the heart.

What health problems are part of catecholaminergic polymorphic ventricular tachycardia?

The most common health issues affecting individuals diagnosed with catecholaminergic polymorphic ventricular tachycardia include dizziness, lightheadedness, and syncope (fainting episodes). These symptoms are caused by ventricular tachycardia, an abnormally fast heartbeat originating from the ventricles of the heart. As the heartbeat speeds up, there isn't adequate time for the heart to fill with blood, resulting in less blood being circulated throughout the body.

For more information regarding the symptoms of catecholaminergic polymorphic ventricular tachycardia, please refer to the "Symptoms" section. You may also reach out to a genetic counselor.
