The acquired mean native QTc intervals and those calculated by the presented formula displayed no significant differences (p > .99 and p > .75). Different electrical parameters can distinguish between symptomatic and asymptomatic patients in different genetic forms of LQTS, indicating that genotype-specific risk stratification approaches based on electrical parameters could help to optimize risk assessment in LQ TS.

The novel Bogossian formula seems to be a reliable tool for QTc interval evaluation in patients with heart failure and right ventricular pacing. 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. the correction formula used to correct the QT-interval for heart rate, age and/or sex, although age and sex are known modulating factors of the QTc-interval.

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.
