WebJan 20, 2024 · The two basic functions of the pacemaker system are pacing and sensing. Pacing refers to depolarization of the atria or ventricles, resulting from an impulse (typically 0.5 msec and 2 to 5 volts) delivered from the generator down a lead to the heart. Sensing refers to detection by the generator of intrinsic atrial or ventricular depolarization ...

WebApr 13, 2024 · Similar to atrial pacing, if the pacemaker is set at 60 beats/min, the pacemaker will only pace the ventricle if the rate falls below 60 beats/min or there is a pause of one second (60 beats/min ÷ 60 sec/min). If the native rate is slow, there will be 100 percent ventricular pacing ( figure 1 ). WebFor pacemakers, brief consideration should be given to the patient’s reliance on the implanted device. Among patients with cardiac pacemakers, approximately 20% are dependent on their pacemaker for moment-to-moment maintenance of adequate rhythm and hemodynamics. This group of patients has a greater risk in the event of de-
