The metrical compression and relaxation of the muscles of the heart is called twinkle. The metrical hole-a-patting of the highways as the blood is pushed forward is called palpitation. It can be felt in the wrist, tabernacles, etc. Palpitation rate is the number of jiffs per twinkles. The number of twinkle is equal to the number of palpitation per nanosecond. If a palpitation rate of an athlete is 96/ min also the number of his twinkle at the same time will also be 96/ min.
