摘要
目的观察高压氧（HBO）治疗对急性心肌梗死（AMI）患者康复期Q—T离散度及心率变异性的影响。方法AMI1个月以上符合Ⅰ期心脏康复条件的患者80例，将其分为2组，治疗组40例，给予HBO治疗辅以基础治疗；对照组40例，只给予基础治疗。HBO治疗15d后比较2组患者Q—T间期离散度及心率变异性的变化。结果HBO治疗组最大Q—T间期变小，Q—T离散度变小，心率变异性增大，交感神经活动下降，迷走神经张力增加。结论HBO治疗有利于AMI康复期患者加快心电活动的恢复。
Objective To study effects of hyperbaric oxygen（HBO） therapy on Q-T dispersion（QTd） and heart rate variability （ HRV ） of the patients with acute myocardial infarction during the rehabilitation. Methods Eighty subjects were randomly divided into HBO treatment group and control group,which both meet the needs of phase Ⅰ cardiac rehabilitation after one month of AMI. Changes of QTd and HRV of the two groups were observed. Results The Q-T max and QTd greatly decreased in the rehabilitation group of HBO, and HRV greatly increased. The tone of sympathetic nerve decreased, while that of vagal nerves increased. Conclusions The HBO therapy can be benifit to the fast recovery of electric activity in the patients with acute myocardial infarction.
