| atrial demand inhibited p. |
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 initiation of a new cycle. Called also AAI p.

| atrial demand triggered p. |
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 and initiates a new pacemaker stimulation cycle. Called also AAT p.
