Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	ischemia
B	infraction
C	embolism
D	fibrillation

Explanation:

Detailed explanation-1: -During ventricular fibrillation, the lower heart chambers contract in a very rapid and uncoordinated manner. As a result, the heart doesn’t pump blood to the rest of the body. Ventricular fibrillation is an emergency that requires immediate medical attention. It’s the most frequent cause of sudden cardiac death.

Detailed explanation-2: -Fibrillation is an uncontrolled twitching or quivering of muscle fibers (fibrils). When it occurs in the lower chambers of the heart, it is called VF. During VF, blood is not pumped from the heart. Sudden cardiac death results.

Detailed explanation-3: -AFib is a quivering or irregular heartbeat called arrhythmia that can lead to blood clots, stroke, heart failure and other heart-related complications. Basically, the heart has its own electrical system. This system makes the signals that start each heartbeat.
