The positive T wave.

OBJECTIVE The instant of maximum slope (Tup) of the T wave in the unipolar electrogram is a well-established measure of repolarisation time (TR). Nevertheless, recent observations on positive T waves have caused a renewed debate. The purpose of this study was to elucidate the mechanism that leads to positive and negative T waves and to investigate which electrogram feature best predicts TR. M...

Consistent with a transient ischemic attack (TIA), his symptoms lasted 30 minutes and had resolved just prior to hospital arrival. He had experienced similar episodes in the past month.

T Wave Oversensing

T wave oversensing is quite a familiar phenomenon to anyone who has watched cardiac monitors for sufficiently long periods in the coronary care unit. The counter starts giving dual beeps for every cardiac cycle instead of one. If it persists during several cycles, the displayed rate goes up and the monitor sounds an alarm indicating 'tachycardia'. This occurs usually when the monitoring lead di...

She continued to have episodes 2 to 3 times a year, and witnesses said she w...
