ABSTRACT:
A method and apparatus for optimizing the sensing circuit of a tachyarrhythmia detector for use with direct heart (cardiac) electrodes. The method is applied to detection of ventricular fibrillation and multifocal ventricular tachyarrhythmia, with rejection of T wave and pacing artifact. The sensing circuit optimized with this method includes a third-order high-pass filter followed by at least one comparator, with the filter corner frequency near 16 Hz and the comparator threshold near 0.40 mV referred to the input, in-band.
