ECG parameters, such as QTcH, TP and TP/QT do not helpful predicting Troponin I elevations in patients on anthracycline-based chemotherapy, and further studies based on hard endpoints, for example, clinical systolic dysfunction occurring at one year, would give better information on their utility. The QT interval of the electrocardiogram is prolonged in right and left bundle-branch block, which is probably due to the conduction defect and delayed depolarization (and thus repolarization) of the heart.

The corrected QTc interval was compared in each patient with the QTc interval during intrinsic rhythm. A total of 163 patients with a cardiac one- or two-chamber pacemaker were included in this prospective, multicentre observational study. The Bogossian formula is a reliable tool for QTc interval evaluation in pacemaker patients with LBBB due to apical or non-apical RV pacing and preserved left ventricular function. An improved method for adjusting the QT interval for heart rate (the Framingham Heart Study). 145 patients with implantable cardioverter defibrillator were included in this prospective multicenter observational study. A New Formula for Estimating the True QT Interval in Left Bundle Branch Block. This site needs JavaScript to work properly. IS - 11 Background: The evaluation of the QT interval in the presence of left bundle branch block (LBBB) is associated with the challenge to discriminate native QT interval from the prolongation due to the increase in QRS duration. Before Methods: However, a slight overestimation of the QT-interval must be respected. In the apical group the QTmc was determined to be 444 39 ms in paced rhythm and the QTc interval 413 36 ms in intrinsic rhythm. 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. Epub 2018 Sep 17. A total of 163 patients with a cardiac one- or two-chamber pacemaker were included in this prospective, multicentre observational study. QTc interval evaluation in patients with right bundle branch block or 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. The Bogossian formula is a reliable tool for QTc interval evaluation in pacemaker patients with LBBB due to apical or non-apical RV pacing.
