[Effect of qigong on electrocardiographic autopower spectrum function].
The Changes of positive rate of 17 coronary heart disease cases with frequency domain-correlative cardiogram (FCG) > or = 7 grades were evaluated with electrocardiographic autopower spectrum function before and after Qigong exercise. 17 Qigong-exerciser aged from 54 to 72 (mean 66 year old, male 5, female 12) underwent Qigong exercise in 65 to 103 days and were evaluated using FCG to compare with pre-Qigong exercise status. The results showed that the positive rate of abnormal electrocardiographic autopower spectrum function of lead V5 (Gxx 1/2) decreased from 59% (10/17) to 0% (0/17), the lead II (Gyy 1/2) from 82% (14/17) to 41% (7/17), P < 0.01 and 0.05. This study suggested that Qigong exercise could significantly decrease the positive rate of abnormal electrocardiographic autopower spectrum function and improve perfusion of coronary artery or cardiac dysfunction produced by myocardial ischemia.
