Introduction:

As we know that the Heart is the pumping organ of the blood. Due to its alternative contraction and relaxation of heart chambers, the blood is directed to the respective blood vessels. The contraction of the heart chambers is called as the systole while the relaxation is called as the diastole. Heart beat is an electric impulse caused by the specialized cardiac muscles of the heart generally referred as the pacemakers.
