<p>CANADIAN 421,206 A system for predicting ventricular tachycardia from electrocardiograph input waveforms. A first means 170A generates a signal representative of the input waveforms exceeding a preselected level. A second filter means 170B 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 200, 210, 220 responsive to the second filter means output. In one embodiment, the input waveforms are digitized 120 prior to processing by the first and second means 170A, 170B. In another embodiment, the input waveforms are signal averaged 150 prior to processing by the first and second means 170A, 170B.</p> |
