An arrhythmia is a generic term for an issue with your heartbeat. Some abnormal heart rhythms may lead to SCA. SCA is an electrical problem with the heart that triggers a dangerously fast heart rate (tachycardia) or irregular rhythm (ventricular fibrillation). SCA is a disturbance in the heart’s electrical system and occurs when the heart suddenly stops beating, leading to a lack of blood flow to the body.

Consult your doctor with any questions regarding any symptoms you may be experiencing and your medical condition.
