Sudden cardiac arrest is the abrupt loss of heart function, breathing and consciousness.
Explanation:
The usual cause of sudden cardiac arrest is an abnormal heart rhythm (arrhythmia), which happens when your heart's electrical system isn't working correctly. The heart's electrical system controls the rate and rhythm of your heartbeat.
Most cardiac arrests occur when a diseased heart's electrical system malfunctions. This malfunction causes an abnormal heart rhythm such as ventricular tachycardia or ventricular fibrillation. Some cardiac arrests are also caused by extreme slowing of the heart's rhythm (bradycardia).
