Abstract

Accurate detection of pacemaker-mediated tachycardia requires a rapid and reliable method for discriminating retrograde atrial activation (RAA) from anterograde atrial activation (AAA). The authors compared two methods of morphology analysis for discriminating RAA from AAA applied to the atrial electrogram: correlation waveform analysis (CWA) and the bin area method (BAM). Both methods were tested on 19 patients undergoing clinical electrophysiology studies. Both CWA and BAM discriminated AAA from 1:1 RAA in 19/19 patients, but BAM reduced the computational demands by a factor of 6
