الموت المفاجئ

Sudden death is a sudden but natural death. The main cause of sudden death is cardiac arrest. 

It is estimated that 12% of natural deaths are sudden deaths. In patients with ischemic heart disease, sudden death is the most common form of death. 

Popularly it is believed that there is a relationship between physical activity and sudden death. But the overall impact is small. 

Some drugs, such as diuretics or antiarrhythmics, can cause arrhythmia and therefore sudden death. Drugs, especially cocaine, also can cause this unexpected death.
