  • Premature ventricular contraction detector and method
    Patent number: 3998214
    Abstract: Premature ventricular contractions are detected by separately rectifying the high and low frequency components of the QRS portion of an ECG waveform, integrating the rectified high frequency signal and using such integral to control the gain of an AGC input circuit, and comparing such integral with the rectified low frequency signal to provide an output signal indicating the occurrence of a PVC.
