Abnormal QT responses to adenosine in subjects with long-QT syndrome

Acute Effects of Low Doses of Red Wine on Cardiac Conduction and Repolarization in Young Healthy Subjects

“…QT interval correction was performed using the Bazett formula (corrected QT = QT ⁄ ÖRR) (Bazett, 1920;Marfella et al, 2001). An alternative correction of QT interval was separately performed using the Fridericia formula (corrected QT = QT ⁄ RR [1 ⁄ 3] ), a method that has been suggested to perform better in terms of rate adjustment success and to minimize the risk of over-or underadjustment in comparison with the standard Bazett's method (Ballo et al, 2006;Strohmer et al, 2007). For any QT interval considered in the analysis, adjustment was made by using the corresponding RR interval measured in the preceding cardiac cycle.…”
