Segmentation of Rabbit Electrogram Based on Wavelet Transform
The segmentation of the signals is main step for further analysis. In case of rabbit's electrograms, similar like human ECGs, is the QRS complex detection the first step of segmentation. The QRS complex detector used in this paper is based o...

Depolarization changes during ischemia detected through time-frequency analysis of the intracardiac electrogram
Epicardial and endocardial electrograms were recorded from isolated perfused rabbit hearts in which local ischemia was induced by occluding the LAD for short to ischemia in paced and non-paced beats. Both the intra-QRS electrogram a...
