Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Quivering or spontaneous muscle contraction of the heart is called:
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: -Ventricular fibrillation is an arrhythmia that starts in your ventricle. This occurs when the electrical signals that tell your heart muscle to pump cause your ventricles to quiver (fibrillate) instead. The quivering means that your heart is not pumping blood out to the rest of your body.

Detailed explanation-3: -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.
