Figure 1 : 

Graphic representation of the differences in corrected QT (QTc) in each electrocardiogram lead and in mean QTc between atrial fibrillation patients (grey) and controls (white). * indicates a significant difference (P <0.05); b indicates a borderline difference (P <0.1).

Figure 2 : 

Uncorrected QT heart rate regression lines for patients and controls, displaying significant interaction. The slope of the regression line for atrial fibrillation (AF) patients is significantly steeper than that for controls (P =0.01). bpm: beats per minute.
