Applicability of a Novel Formula (Bogossian formula) for Evaluation of the QT‐Interval in Heart Failure and Left Bundle Branch Block Due to Right Ventricular Pacing

Background The presence of left bundle branch block (LBBB) due to right ventricular pacing represents a particular challenge in properly measuring the QTc interval. In 2014, a new formula for the evaluation of QT interval in patients with LBBB was reported. Methods 145 patients with implantable card...

Zusammenfassung:	Background The presence of left bundle branch block (LBBB) due to right ventricular pacing represents a particular challenge in properly measuring the QTc interval. In 2014, a new formula for the evaluation of QT interval in patients with LBBB was reported. Methods 145 patients with implantable cardioverter defibrillator were included in this prospective multicenter observational study. Inclusion criteria were: no permanent right ventricular stimulation, an intrinsic QRS interval of
