DETECTION AND DISPLAY OF IRREGULAR PERIODIC WAVEFORMS
First Claim
1. A method for display, comprising:
- acquiring an electrical signal from a heart of a subject over multiple heart cycles;
partitioning the signal into a succession of synchronized segments having respective start times at a selected annotation point in the heart cycles;
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; and
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.

Abstract
A method for display, consisting of acquiring an electrical signal from a heart of a subject over multiple heart cycles. 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.

8. Apparatus, comprising:
-
a display screen; and a processor, which is configured to; acquire an electrical signal from a heart of a subject over multiple heart cycles, partition the signal into a succession of synchronized segments having respective start times at a selected annotation point in the heart cycles, overlay respective graphical representations of the synchronized segments in the succession on the 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, and gradually decrease a display intensity of each segment overlaid on the display screen as a decaying function of a time elapsed since the respective display time. - View Dependent Claims (9, 10, 11, 12, 13, 14)
