The paper reports the effect of qigong on the heart function. The trainees involved in this experiment were 37 middle-aged intelligentsia, 25 males and 12 females between 35 to 45 years old. During the first three months, the subjects accepted the emitted qi remedy twice a week besides their independent exercises for an hour, twice a day. In the next nine months, the trainees practiced by themselves without the emitted qi remedy. A RM-6000 polygraph was used to record electrocardiogram (ECG), phonocardiogram(PCG) and carotid artery pulse (CAR) simultaneously three months before and after the emitted qi remedy as well as a year later, respectively, to determine the left heart systolic time intervals. After three months of the emitted qi remedy the trainees' heart rate (HR), electromechanical systole(Q-S2), projection period (PEP), left ventricle contraction time (LVET), systolic pressure (SP) and diastolic pressure (DP) were not statistically different from those of three months before. While after one year of practice, the measurements were found to have a significant difference compared with those of before the exercise in all the indices mentioned above except HR, isovolumetric contraction time (lVCT)and Q-S2. The following table indicates that qigong practice improves the heart function. [table shown].
