Asymmetric sympathetic effects on HR but not Ees in animals should not change practice; leaves open sided innervation in human autonomic studies.
Although the mechanism of sympathetic regulation of cardiac contractility differs between left and right nerves, this difference does not affect the apparent response of left ventricular end-systolic elastance to dynamic sympathetic stimulation.
Miyano et al. (1998) studied this question.
