Pacemaker
91ventricular 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 …
92artificial pacemaker — An electronic device that is implanted in the body to monitor heart rate and rhythm. It gives the heart electrical stimulation when it does not beat normally. It runs on batteries and has long, thin wires that connect it to the heart. Also called …
93artificial pacemaker — noun an implanted electronic device that takes over the function of the natural cardiac pacemaker • Syn: ↑pacemaker • Hypernyms: ↑electronic device …
94Kent's Pacemaker — The Kent s Pacemaker was an American automobile manufactured only in 1900. Offered by the Colonial company of Boston, it was a steam car which had one front steering wheel, and three rear wheels. The center of these drove; the others, an outer… …
95Natural pacemaker — The natural pacemaker of the heart is the sinus node, one of the major elements in the cardiac conduction system, the system that controls the heart rate. This stunningly designed system generates electrical impulses and conducts them throughout… …
96wandering pacemaker — n a back and forth shift in the location of cardiac pacemaking esp. from the sinoatrial node to or near the atrioventricular node …
97AAIR pacemaker — an atrial demand inhibited pacemaker that is responsive to the patient s respiratory rate and thus to exercise and metabolic needs …
98antitachycardia pacemaker — an implanted pacemaker that terminates tachycardia by delivering one or more pacing stimuli; it may require arrhythmia detection and device activation by the patient or may detect arrhythmias and deliver stimuli automatically …
99asynchronous pacemaker — an artificial cardiac pacemaker that delivers stimuli at a fixed rate, independent of any atrial or ventricular activity …
100atrial asynchronous pacemaker — an artificial cardiac pacemaker that stimulates the atrium at a constant rate, without sensing atrial or ventricular activity; now rarely used except to initiate or terminate some tachycardias. Called also AOO p …
