摘要
【目的】研究美托洛尔干预慢性充血性心力衰竭后心率震荡的变化。【方法】选择有室性早搏的CHF患者60例,分为美托洛尔治疗组31例及对照组29例,所有患者行24 h动态心电图监测计算心率震荡的初始值(TO)、震荡斜率(TS)。【结果】美托洛尔治疗组TO>0,对照组则TO<0;美托洛尔治疗组的TS明显低于对照组。且治疗后HRT明显改善,TO下降,TS升高。【结论】美托洛尔可改善CHF的自主神经功能,进而改善HRT。
[ Objective ] To observe the therapeutic effect of metoprolol on heart rate turbulence （HRT） in patients with congestic heart failure （CHF）. [Methods] There 60 patients with premature ventricular beats were divided into metoprolol group consisted of 31 cases and control group consisted of 29 cases . All patients were examined with ambulatory electrocardiogram monitoring for twenty-four hours, and turbulence onset （TO） and turbulence slope （TS） were analyzed, Patients in the metoprolol group were given orally metoprolol. [Results] TO were 〈0 in the control group and〉0 in the metoprolol group. TS was higher in the control group than that of the CHF group. TO decreased and TS increased respectively after oral administration of metoprolol for a month in the metoprolol group. [ Conclusion ] metoprolol can improve function of autonomic nerve in CHF patients in addition to improvement of HRT.
