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. WebAn implantable pacemaker, defibrillation, or cardiac resynchronization therapy (CRT) system relieves symptoms of heart rhythm disturbances. It does this by restoring normal heart rates. A normal heart rate provides your body with the proper amount of blood circulation.

WebMay 24, 2016 · Sensing is the ability of the pacemaker to detect the heart’s intrinsic electrical activity. The lower the sensitivity setting, the more readily it will detect a subtle signal. In contrast, the higher the sensitivity setting, … WebIn dual-chamber pacemakers, the lower rate is the rate at which the pacemaker will pace the atrium in the absence of intrinsic atrial activity. The upper tracking rate limits the rate at which the ventricle can pace in the presence of high atrial rates. In rate-responsive modes, the upper activity (sensor) rate provides the limit for sensor ...
