摘要
目的探讨急性心肌梗死（AMI）溶栓后心率变异性（HRV）的近日节律变化。方法将我院AMI患者按照是否溶栓及溶栓再通与否分为再通组、溶栓未通组、未溶栓组各40例，采用动态心电图评估HRV的变化规律。结果再通组患者TF、LF、HF明显高于未通组及未溶栓组，差异有显著性（P〈0．05）。再通组患者LF／HF明显低于未通组及未溶栓组，差异有显著性（P〈0．05）。未通组患者TF、LF、HF及LF／HF与未溶栓组比较差异无显著性（P〉0．05）。结论心肌梗死溶栓再通能明显改善HRV的近日节律。
Objective To investigate the circadian of heart rate variability （HRV） in cases with acute myocardial infarction （AMI） after thrombolysis. Method The cases with AMI were divided into the recanalization group, the no-recanalization group and the no-thrombolysis group. The dynamic electrocardiogram was used to evaluate the HRV. Results The levels of TF, LF and HF in the recanalization group were obviously higher than those in no-recanalization group and the no- thrombolysis group, and there were significant differences among them （P 〈0.05）. The levels of LF/HF in therecanalization group were much lower than those in no-recanalization group and the no- thrombolysis group, with statistical significant difference in them （P 〈 0.05）. The levels of TF, LF, HF and LF/HF in the no-thromholysis group were same to those in no-recanalization group, and there was no significant difference （P 〉 0.05）. Conclusion The circadian of HRV can be obviously improved by recanalization with AMI after thrombolysis.
