[Effects of electroacupuncture pretreatment on ischemic arrhythmia and intracellular calcium oscillation in single cardiocyte isolated from rats with myocardial ischemia and reperfusion].

Objective: To observe the inhibitory effects of acupuncture pretreatment on arrhythmia and intracellular calcium ([Ca2+]i) oscillation in single cardiocyte in rats subjected to myocardial ischemia-reperfusion (MIR).

Methods: Male SD rats were evenly randomized into normal control (NC), MIR and electroacupuncture (EA) groups. MIR was performed by ligation (30 min) and reperfusion (10 min) of the left anterior descending coronary artery in vivo in rats or in the isolated and perfused rat heart subjected to a 40 min global ischemia followed by a 10 min reperfusion.
