The electrical signal is partitioned into a succession of synchronized segments having respective start times at a selected annotation point in the heart cycles. The method includes overlaying respective graphical representations of the synchronized segments in the succession on a display screen, such that each segment is first presented on the display screen with an initial display intensity at a respective display time corresponding to a respective start time of the segment. The method further includes gradually decreasing a display intensity of each segment overlaid on the display screen as a decaying function of a time elapsed since the respective display time.3/5 START RECEIVE A SERIES OF HEART SIGNALS 206 202 PARTITION SERIES INTO SUCCESSION OF SEGMENTS 204 SYNCHRONIZE SEGMENTS OVERLAY GRAPHS OF SYNCHRONIZED SEGMENTS 206 ON DISPLAY SCREEN, WHILE GRADUALLY REDUCING INTENSITY OF SEGMENTS WITH TIME AND SUMMING INTENSITIES AT OVERLAPPINNG POINTS OF GRAPHS END FIG. 3
