ΔHR/ΔMAP, heart rate response to the spontaneous change in mean arterial pressure, beats min−1 mmHg−1.

**

Significant differences between two groups at rest, P < 0.01.

††

Significant differences between at rest and during exercise in KO mice, P < 0.01.

§

ΔHR was highly correlated with ΔMAP in all mice at the level of P < 0.00001 (n = 4964–11906).
