Potential ventricular tachycardia prediction system for patients

摘要

A first filter generates a signal representative of the input waveforms exceeding a preselected level. A second filter has its gain controlled responsive to the first filter output signal, and provides an output responsive to said input waveforms. Ventricular tachycardia is then predicted responsive to the second filter output. The input waveforms are digitised prior to processing by the two filters. Alternatively, the input waveforms are signal averaged prior to processing by the filters.
