摘要： A biventricular stimulation device comprises a pulse generator for delivering stimulation pulses at least to the ventricles of a patient's heart. An evoked response detector has first and second, independent ventricular sensing channels for ventricular evoked response detection in the ventricles. The pulse generator is controlled to deliver stimulation pulses (106) to the second ventricle (RV) with a VV time delay after stimulation pulse delivery (104) to the first stimulated ventricle (LV) which is shorter than an evoked response detection time window (106) following the delivery of the stimulation pulse (104) to the first ventricle. The evoked response detector is arranged to close the evoked response detection time window (106) or discard detections therein in response to the emission of a stimulation pulse (107) to the second ventricle (RV) during the evoked response detection time window (106) of the first stimulated ventricle (LV).

摘要： An implantable medical device, IMD, (100) is connectable to at least one ventricular lead (210) having a ventricular basal electrode (214) and a ventricular apical electrode (212). The IMD (100) comprises a pulse generator (120) for generating pacing pulses applied to a heart (10) through the ventricular lead (210). The operation of this pulse generator (120) is controlled by a controller (130) that is configured to control the pulse generator to first deliver a pacing pulse to the ventricular basal electrode (214) to stimulate the basal portion of the ventricle (12, 14) before a pacing pulse is delivered to the apical portion of the ventricle (12, 14) by the ventricular apical electrode (212). This pulse sequence achieves a biologically more correct cardiac stimulation and a contraction pattern that reduces the risk for valvular regurgitation.
