Abstract

Smoothed Pseudo Wigner Distribution (SPWD) was used to track changes in activation intervals during VF. In swine, electrograms were digitized from an epicardial sock with 64 electrodes. Dominant frequencies, or reciprocal of activation intervals, were estimated every 40 ms using an SPWD algorithm. Results show that the SPWD can be used to track changes in activation intervals during VF.
