Procedure for determining the input resistance. Steps followed to quantify the input resistance and the intracellular thresholds in the papillary muscles of the hearts of the control rats: (a) injection of the pulse current in late diastole to evaluate the input resistance; (b) determination of the intracellular threshold; (c) simultaneity and shape of the depolarization phase of the action potentials; (d) zero potential of both records obtained from the same cell.
