The Bogossian formula is a reliable tool for QTc interval evaluation in pacemaker patients with LBBB due to apical or non-apical RV pacing. The QTmc interval was calculated with the Bazett formula, and this was compared with the QTc interval during intrinsic rhythm. QT interval prolongation is associated with a risk of polymorphic ventricular tachycardia and torsades de pointes, and there was no significant difference between the QTc interval in AF and SR when assessed by Fredericias formula.
