Application of the Bogossian formula for evaluation of the QT interval in pacemaker patients with stimulated left bundle branch block. The most commonly used QT correction is that of Bazett which was proposed in 1920. This tool is a statistical model and is not a substitute for an individual treatment plan developed by a health care provider with personal knowledge of a specific patient. Before The Bogossian formula showed a significant deviation from the actual QTc interval with both the Bazett and the Fridericia formulas. AU - Chasan,R, The results confirm that JTc, as an index of repolarization, is independent of ventricular depolarization and can be applied for predicting QTc in patients with LBBB. Results JTc (QTc-QRS) interval was preserved before and after LBBB (328.9 25.4 ms before LBBB vs. 327.3 ms post LBBB (p = 0.550).

QTc interval evaluation in patients with right bundle branch block or 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. The QT interval measured during LBBB was corrected using the Bogossian formula to obtain the "modified QT" (QTm).
