Method for preventing the temporal coincidence of paced and spontaneous cardiac activities

摘要

Method for avoiding the coincidence in time of paced and spontaneous heart actions during transmission of cardiac stimulating pulses in the atrium or the chamber of a heart, wherein the step of transmission of the cardiac stimulation pulse is executed so controlled in time that the simultaneous or superimposed occurrence of a spontaneous cardiac action and an evoked potential is prevented, and in the case of an atrium-synchronous pacing the transmission of a cardiac stimulation pulse in the ventricle, the delay between the spontaneous atrium action and stimulation in the ventricle than the natural AV conduction time is set to be smaller and / or in the case of ventrikelinhibierten stimulation in an first step, a sequence of several cardiac stimulating pulses at a first rate, then in a second stage a second series of heart pacing pulses at a second, opposite the first substantially abruptly increased rate and then in a third Stu fe is transmitted, a third series of heart pacing pulses at a third, opposite the second substantially abruptly again reduced rate, wherein during at least the first output to the third rate of cardiac stimulating pulses is prevented a simultaneous or superimposed occurrence of a spontaneous cardiac action and an evoked potential.
