In order to explore the effects of acupuncturing the Heart Meridian on heart function of severe scald
the Wistar rats with 30 % TBSA Ⅲ°scald were used. The changes of myocardial mechanics and the contents of cardiac troponin T in serum were observed in the group of scald and the group of acupuncturing Heart Meridian. The result indicated that the range of change of myocardial mechanics and cardiac troponin T in the group of acupuncturing Heart Meridian is lower than that in the group of scald. The result suggested that acupuncturing Heart Meridian has an improving effects on early heart dysfunction of severe scald.
