(30) 
VerifiedB
Your patient has a DDD pacemaker. Briefly explain the meaning of each of these letters.
(31) VerifiedA dual-chamber pacemaker can also be called a DDD pacemaker, indicating that both the atrium and ventricle are paced (D), both chambers are sensed (D), and the pacemaker has both a triggered and an inhibited mode of response (D). When spontaneous atrial depolarization does not occur within a preset interval, the atrial pulse generator fires and stimulates atrial depolarization at a preset rate. The pacemaker is programmed to wait, simulating the normal delay in conduction through the AV node (the PR interval). The "artificial" or "electronic" PR interval is referred to as an "AV interval." If spontaneous ventricular depolarization does not occur within a preset interval, the pacemaker fires and stimulates ventricular depolarization at a preset rate.
