The issue that QT duration is not exclusively depending on the prolonged depolarization time during LBBB, but that there are many features including heart rate, electrophysiological remodeling and clinical condition of the patient that may contribute is raised, however, in some population the authors' formula works fairly well in others it tends to overestimate the QTtime. In the non-apical group these values were 43034ms in paced and 41632ms in intrinsic rhythm. Herzschrittmacherther Elektrophysiol.

Conclusion: The Bogossian formula is a reliable tool for QTc interval evaluation in pacemaker patients with LBBB due to apical or non-apical RV pacing. Inclusion criteria were: no permanent right ventricular stimulation, an intrinsic QRS interval of <120 ms, and reduced left ventricular function. 2016 in press Bogossian H, Frommeyer G, Ninios I, Hasan EP F, et al.
