The heart has an internal electrical system that controls the rhythm of the heartbeat. Problems can cause abnormal heart rhythms, called arrhythmias. There are many types of arrhythmia. During an arrhythmia, the heart can beat too fast, too slow, or it can stop beating. Sudden cardiac arrest occurs when the heart develops an arrhythmia that causes it to stop beating. This is different than a heart attack, where the heart usually continues to beat but blood flow to the heart is blocked.

There are many possible causes of cardiac arrest. They include coronary heart disease, heart attack, electrocution, drowning, or choking. There may not be a known cause to the cardiac arrest.

Without medical attention, the person will die within a few minutes. People are less likely to die if they have early cardiopulmonary resuscitation (CPR) and defibrillation. Defibrillation is delivering an electric shock to restore the heart rhythm to normal.

All medicines have benefits and risks. The risks of medicines are the chances that something unwanted or unexpected could happen to you when you use them, such as Cardiac Arrest. Side effects can be temporary or long-lasting, and vary in seriousness. It is important to monitor drugs for Cardiac Arrest and any other side effects. Sometimes Cardiac Arrest can be reduced with the right treatment.
