What is Electrophysiology?
Electrophysiology: The science of the study of flow of electricity controlling the movement of the heart
The heart is a pump responsible for the blood flow inside the artery and veins
Any upset or malfunction of electricity Organization certainly cause trouble and energizes the contraction of the heart muscle and therefore disturbed blood flow to organs of the body, which may cause death in cases of continuous turmoil and rapid
