Popis: Transient left bundle branch block (LBBB) may occur in association with high left ventricular (LV) filling pressure and/or global systolic LV dysfunction in patients with heart failure.1 We herein present a patient who had undergone permanent His bundle pacing (HBP) for complete infranodal heart block and developed transient LBBB because of a massive increase in the His bundle (left bundle) pacing threshold [ie, HB(LB) pacing threshold] associated with acute heart failure. Maintenance of electrical synchrony with recruitment of LBBB at higher pacing output might have led to prompt myocardial recovery and improvement of the HBP threshold.
