Figure 2. Effect of Sex Hormones on QT Duration.

Figure 2

A. Exemplary, representative ECG traces of individual rabbits at 300 ms RR intervals. QT durations are indicated. B. QT indices in n=6 rabbits after 4 weeks of hormone-treatment calculated based on QT and RR intervals acquired over 24-hours of ECG monitoring. * p<0.05. C-F. QT/RR ratio in n=6 rabbits at baseline (grey) and after 4 weeks of treatment (color). Arrows indicate the direction of changes in QT/RR ratio. * p<0.05. G. QT/RR ratio in n=6 adult SF and SM. * p<0.05.
