Heart & Vasculature, Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc. A practice formula to eliminate the effect of depolarization changes on QT interval in patients with R BBB is developed and allows a rapid and practical method for QT correction in RBBB in clinical practice. International Journal of Cardiology. Abb.). The newest formula to evaluate QT interval in the presence of LBBB suggests: modified QT during LBBB = measured QT interval minus 50% of LBBB duration. All measurements were performed by an experienced electrophysiologist and a trainee who worked independently and in a blinded manner. Eighty-three patients (78 9 years; male n = 83) with apical and eighty patients (71 13 years; male n = 80) with non-apical RV pacing were included in this study.
