Abstract
It well known that the magnitude of contraction and the shape of action potential depend upon the stimulation frequency and the duration of resting period (positive and negative staircase). Although the underlying mechanism of the staircase phenomenon is not fully understood, it has been suggested that staircase could be related to the intracllular
