Abstract :
Unipolar electrograms contain an electrical component produced by changes in the reference potential as a function of time during ventricular excitation. The purpose of this work was to evaluate and remove this component from experimental data. Successful removal of this component resulted in signal morphology that is consistent with the potential distributions
