Conclusion In combination with the Hodge formula, the Boggosian formula delivered the best results in comparing the true QTc interval in narrow QRS with the QTmc interval in the presence of a bifascicular block. In addition to the standard electrical parameter QTc, we assessed markers for regional electrical.

KW - Pacemaker Erkapic D, Frommeyer G, Brettner N, Szener K, Crijns HJGM, Seyfarth M, Hamm CW, Bogossian H. Clin Cardiol. This 'Bogossian' formula was reported to be a reliable tool for QT interval estimation in patients with heart failure and right ventricular pacing [ 9 ]. Inclusion criteria were: no permanent right ventricular stimulation, an intrinsic QRS interval of <120 ms, and reduced left ventricular function. The site is secure. Weipert, K F., et al. 2004 Sep;1(3):355-63. doi: 10.1016/j.hrthm.2004.03.065. Methods: FOIA eCollection 2020 Oct. QTc interval evaluation in patients with right bundle branch block or bifascicular blocks. An approach to the ECG in this context, and a step-by-step guide to manually measuring and correcting the QT interval, and an approach to management in common hospital-based clinical scenarios are presented. 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.

Conclusion: In combination with the Hodge formula, the Boggosian formula delivered the best results in comparing the true QTc interval in narrow QRS with the QTmc interval in the presence of a bifascicular block. The purpose of this study is to validate the newest formula to evaluate QT interval in the presence of LBBB with the aim of validating the abovementioned formula in the clinical setting. Left bundle branch potential predicts better electrical synchrony in bradycardia patients receiving left bundle branch pacing.
