Mentions: IEGM scans eventually revealed the cause of the unexpected sensing error: while the R-wave amplitude exceeded 15 mV with a bundle branch block, we sensed a significantly lower R-wave amplitude with a narrow QRS (5.8–6.3 mV in the last two QRS) (Fig. 2). At a sensitivity of 5 mV, the pacemaker only intermittently sensed a narrow QRS. We have now lowered the ventricular sensitivity to an appropriate level.Fig. 2
