WebMay 10, 2024 · Once the pacing threshold is determined, the pacemaker is set to deliver a pulse of at least twice the threshold. Normally, the sensitivity is set to 1–2 mV so that intrinsic ventricular depolarization can be sensed by lead and no current/spike will be generated from pulse generator. WebDecrease the pacemaker sensitivity (↑ #) Treat shivering and seizures If pacing with an external pacemaker, change the EKG lead to minimize the size of the P wave or the T wave ... Reassess the pacing threshold and increase the mA as needed. Replace the pacemaker battery or pulse generator as needed.
