The symptoms typically start with ventricular tachycardia (VT) during physical activity or emotional stress:
Fainting is commonly the first sign of the disease Light-headedness or dizziness Palpitations or unpleasant awareness of the heartbeat
Sometimes the ventricular tachycardia goes away, and symptoms stop. At times, ventricular tachycardia can turn into ventricular fibrillation (VF) in which the ventricles quiver and are unable to pump blood. This sudden loss of heart function leads to sudden cardiac arrest. A person stops breathing and becomes unresponsive. Unfortunately, sudden cardiac arrest is sometimes the first sign of CPVT. Sudden cardiac arrest can lead to sudden cardiac death.
