Abstract :
Potential maps recorded from the body surface during PTCA-induced inflation provide a controlled study of the electrocardiographic changes caused by severe ischemia. The authors apply the temporal wavelet transform to this data to separate smooth and rapidly varying parts of the waveforms. They hope to reduce alignment sensitivity, retain temporal resolution and dynamic information, and extract features which reflect the ischemia-induced changes.<>
