The Bogossian formula is a reliable tool for QTc interval evaluation in pacemaker patients with LBBB due to apical or non-apical RV pacing. A novel and practical method that might facilitate discrimination between patients with apparent L BBB and true LBBB by comparing Q-LV/QRS ratios during intrinsic activation and during RV stimulation is presented.

The QTmc interval was calculated with the Bazett formula, and this was compared with the QTc interval during intrinsic rhythm. The ECG pattern of high-grade LAD stenosis has proven to be an important marker ofhigh-risk patients with chest pain and may also be seen in patients with a right ventricular pacemaker on resumption of native QRS conduction. Left bundle branch potential predicts better electrical synchrony in bradycardia patients receiving left bundle branch pacing.

The right bundle branch block (RBBB) and the bifascicular blocks affect QRS duration in the right precordial leads, which are usually used for QT interval determination. Eighty-three patients (789years; male n=83) with apical and eighty patients (7113years; male n=80) with non-apical RV pacing were included in this study.

Here we demonstrate the applicability of the "Bogossian formula" in pacemaker patients with LBBB due to apical or nonapical right ventricular (RV) pacing and preserved left ventricular function. The QT interval measured during LBBB was corrected using the Bogossian formula to obtain the modified QT (QTm).

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.
