T‐wave oversensing in pacemakers is rare because the set sensitivity is generally fixed. However, several models of pacemaker employ automatic sensitivity adjustment. Here, we present two cases of atrioventricular block treated by implantation of the pacemaker with automatic sensitivity adjustment. After implanting the pacemaker with automatic sensitivity adjustment, ventricular pacing suppression...
If a permanent pacemaker lead is misplaced in the left ventricle (LV), the lead may interfere with normal functioning of the heart leading various complications, including heart rhythm problems and blood clots. In our case, the LV lead that passed through the patent foramen ovale and was misplaced into the LV was detected in a 78‐year‐old patient who presented with embolic stroke. Thrombus regression...
Left bundle branch pacing (LBBp) is a promising alternative to conventional biventricular pacing cardiac resynchronization therapy. The left anterior fascicle (LAF) is adjacent to the left ventricular outflow tract, while the left posterior fascicle (LPF) dominates a broader area of the left ventricle. Whether LAF or LPF dominates ventricular activation has not been determined. We present the case...
