Web4 Jun 2024 · Undersensing occurs when the pacemaker fails to sense native cardiac activity. Results in asynchronous pacing. Causes include increased stimulation threshold at … Web14 Apr 2024 · This shows that the sensing function of the pacemaker is normal. Electrocardiogram (Fig. 14.16a) shows that the pacemaker senses the QRS of the sinus beat (S) and postpones the next pacing stimulus (marked *). If the pacemaker did not sense the intrinsic QRS (S), next pacemaker stimulus should have come at the fixed interval marked ).
