Figure 4. Post-exercise HR changes in symptomatic and asymptomatic LQTS patients.

Figure 4

Percent reduction in HR from peak exercise to the first minute after cessation of exercise in the SA and Non-SA LQT1 patients (IKs−) according to presence or absence of symptoms. The horizontal lines at 17% and 11.5% represent the upper and the lower tertiles of the entire LQT1 population (n=95). The odds ratios for the risk of cardiac events are respectively 3.28 and 0.24.
