Sudden cardiac death (SCD) is an unexpected natural collapse due to cardiac cause within a short period of time as a result of sustained ventricular tachycardia or ventricular fibrillation. Such type of rapid death is mostly attributed to a cardiac arrhythmia that occurs particularly in patients with coronary heart disease. The episode is referred to as SCA (or aborted SCD) if an intervention (defibrillation) or spontaneous reversion restores circulation. However, the use of SCD to describe both fatal and non-fatal cardiac arrest persists by convention.
The present article tries to explore risk factors and etiology contributing coronary heart disease that ultimately leads to end of life. Cardiac diseases leading to the genesis of the arrhythmia result in cardiac collapse and sudden death. These varied sickness and their association with sudden death is poorly understood. The…
