I know, I know. Everyone’s eyes are glazing over. But for the record, this is another well done animal study by the Longhurst group on anesthetized cats using electroacupuncture on PC 5 and PC 6 which is shown to blunt the cardiodepressor response of phenylbiguanide(PBG) or cardiac vagal afferent stimulation. For those interested, please click through to the link. Conclusion below.

Thus EA at P5-6 decreases PBG evoked hypotension and bradycardia as well as the NAmb PBG-sensitive preganglionic cardiac vagal outflow through opioid and GABA neurotransmitter systems.
