Figure 3 Differential Risk for Arrhythmic Events According to Resting HR
Differential risk for arrhythmic events among MCs according to resting heart rate (HR) off BB and QTc. The dashed horizontal line represents the predefined cut-off for QTc ( or >500 ms), whereas the dashed vertical line corresponds to the first tertile (60 beats/min) of the HR values distribution. Among the 56 mutation carriers included in the analysis of resting HR in the absence of BB, 1 symptomatic patient had a nonmeasurable QTc because of right bundle branch block. QTc = QT interval corrected for heart rate; other abbreviations as in Figures 1 and 2.
