Abstract
A system for predicting ventricular tachycardia from electrocardiograph input waveforms. A first means generates a signal representative of the input waveforms exceeding a preselected level. A second filter means has its gain controlled responsive to the first means output signal, and provides an output responsive to said input waveforms. Ventricular tachycardia is then predicted responsive to the second filter means output. In one embodiment, the input waveforms are digitized prior to processing by the first and second means. In another embodiment, the input waveforms are signal averaged prior to processing by the first and second means.
