Ventricular late potential detection can be used as a non-invasive diagnostic tool, but traditional detection techniques need around 300 heartbeats and fail to obtain the beat-to-beat information. This paper combines a modified signal averaging and an adaptive enhancer to deal with non-stationary environments and get beat-to-beat information from as little as 60 beats. In the ventricular late potential region of the recovered signal, discernible patterns indicate the presence or not of such waveforms. A maximum absolute value “averaging” can emphasize the boundaries of the QRS complex even further to successfully detect ventricular late potentials.
