Modes of cardiac pacing: Nomenclature and selection

WebMar 24, 2024 · A traditional pacemaker generator is placed outside of your heart, either in your chest or abdomen. It is connected via wires to electrodes inside one to three heart chambers. Single- and double-lead pacemakers send pulses to the right side of the heart. A biventricular pacemaker sends pulses to both ventricles and an atrium. WebJul 25, 2024 · Pacemaker mediated tachycardia is a type of arrhythmia that happens in patients with dual-chamber pacemakers due to reentry. Patients who develop this arrhythmia can develop palpitations, dizziness, or even syncope. The cornerstone of management involves reprogramming of the pacemaker to increase the atrial refractory … The sensitivity of the pacemaker is actually a setting on the box, where the lower the number, the more sensitive the pacemaker. The actual maximum sensitivity of the pacemaker is very high - when the electrode is freshly inserted, it can potentially detect very subtle changes in local electrical activity. See more In the barest sense, the rate setting on the pacemaker is the knob which controls your cardiac output. It is the number of times the pulse generator … See more Thus: 1. Put the pacemaker in a VVI, AAI or DDD mode (i.e. endogenous cardiac activity should inhibit the pacemaker. 2. Change the rate to … See more The electrodes do not only pace, they also sense the electrical activity at the myocardial surface. One can define the sensitivity of a pacemaker electrode as the minimum myocardial … See more The output of a pacemaker is the current (measured in milliamperes, mA) which it produces as a brief pulse.

WebJul 7, 2024 · NBG Pacemaker Code (2002) Position I: Chambers Paced Refers to chambers paced. Position II: Chambers Sensed Refers to the location where the pacemaker senses native cardiac electrical activity. Position III: Response to Sensing Refers to pacemakers response to sensed native cardiac activity. WebTurn the pacemaker to VVI and the sensitivity to zero. The pacemaker should sense every beat and probably other artifactual ECG finding and fire rarely. b. Slowly turn up the mV for sensing until asynchronous pacing is seen (this decreases the sensitivity for detecting native electrical activity). This is the sensing threshold.
