Figure 6 Impact on Arrhythmic Risk of HR and BRS

The BRS and resting HR off BB in the entire group ages 26 to 47 years. Differential probability of being symptomatic among MCs according to the combination of both BRS and HR values below or above the predefined cut-off. The gray quadrant represents the distribution of symptomatic and asymptomatic patients with relatively lower BRS (12 ms/mm Hg) and HR (60 beats/min) values in comparison with the other permutations of the 2 autonomic markers. The percentage of symptomatic MCs increases from 20% to 87.5%. Abbreviations as in Figures 1 and 2.
