atrial demand triggered pacemaker — an artificial cardiac pacemaker that delivers stimuli to the atrium at a fixed rate in the absence of sensed atrial activity; spontaneous cardiac activity triggers pacemaker output, which falls ineffectively in the myocardial refractory period… … Medical dictionary
ventricular demand triggered pacemaker — an artificial cardiac pacemaker that delivers stimuli to the ventricle at a fixed rate in the absence of sensed ventricular activity; spontaneous cardiac activity triggers pacemaker output, which falls ineffectively in the myocardial refractory… … Medical dictionary
atrial demand inhibited pacemaker — an artificial cardiac pacemaker that delivers stimuli to the atrium at a fixed rate in the absence of sensed atrial activity; spontaneous cardiac activity causes inhibition of pacemaker output, termination of the current stimulation cycle, and… … Medical dictionary
ventricular demand inhibited pacemaker — an artificial cardiac pacemaker that delivers stimuli to the ventricle at a fixed rate in the absence of sensed ventricular activity; spontaneous cardiac activity causes inhibition of pacemaker output, termination of the current stimulation cycle … Medical dictionary
