Method for combiner cardiac pacing and defibrillation

摘要: A method is disclosed for combined cardiac pacing and defibrillating with an implanted pacer/defibrillator having sensing leads connected to the atrium ventricle. P-waves R-waves are sensed, V--V timer a V--A reset if R-wave sensed. If sensed during interval, stimulus ventricle inhibited. P-wave In arrhythmia therapy provided determined be present. ventricular rate greater than selected tachycardia but less fibrillation rate, then determination made whether atrial so, timers reset, not provided. present, charging of capacitor commences ceases, discontinues. charged still shock delivered heart time period that outside vulnerable zones
