Abstract :
The authors have developed a computer program, called AP, that automatically detects and locates activation events in bipolar electrograms. AP uses a slope threshold to detect events and a pattern-matching technique to locate the time of activation within each activation waveform. For sinus rhythm and paced and ectopic contractions AP has a detection sensitivity of 0.942 and mislocates 16.4% of the true detections by a mean of 1.59 ms. For ventricular fibrillation the detection sensitivity is 0.882 with 27.1% of the true detections being mislocated by a mean of 3.11 ms.<>
