Hypothesis-generating for ischemic electrogram analysis; leaves open human validation before clinical mapping use.
A novel discriminant function based on biophysical principles accurately predicts activation time of complex unipolar electrograms in ischemic canine epicardium, potentially improving activation mapping.
Caref et al. (2011) studied Ischemic canine epicardium (postinfarction heart). Discriminant function analysis of unipolar electrograms was evaluated on Prediction of activation time of complex fractionated EMGs. A discriminant function analysis incorporating Voltage, -dV/dt, and Ratio improved the prediction of activation time of complex fractionated electrograms from ischemic canine epicardium to 90%.
