Supports neurally mediated coronary flow in intact innervation; hypothesis-generating for TENS in syndrome X/CAD, trials needed before practice change.
Does transcutaneous electrical nerve stimulation increase coronary blood flow velocity in patients with syndrome X, coronary artery disease, or heart transplants?
Transcutaneous electrical nerve stimulation increases resting coronary blood flow velocity in patients with intact cardiac innervation, suggesting a neurally mediated microcirculatory effect.
Chauhan et al. (1994) studied this question.
