目的：探讨经皮冠状动脉介入治疗对 Wellens 综合征患者的窦性心率震荡（heart rate turbulence ，HRT）的影响。方法选取 Wellens 综合征患者59例为 Wellens 综合征组，心电图有类似心肌缺血的改变但经冠状动脉造影排除冠状动脉狭窄病变患者64例作为对照组，记录患者基本资料，分别于术前、术后1天行24h 动态心电图监测，计算震荡初始（TO）、震荡斜率（TS）、震荡斜率时间（TT）。结果 Wellens 综合征组 TO 及 TT 显著高于对照组，TS 显著小于对照组，差异均有统计学意义（P＜0.05）。与血运重建术前比较，Wellens 综合征组术后1天 TO 、TS 和 TT 均较术前改善，差异均有统计学意义（P ＜0.05）。结论血运重建能够改善 Wellens 综合征患者的心脏自主神经功能。%Objective To investigate the impact of PCI on heart rate turbulence index of patients with Wellens ’syndrome .Methods 59 patients with Wellens’syndrome were selected as Wellens’syndrome group .64 were selected as control groupwhich with electrocar-diogram similar to ECG changes while percutaneous coronary angiography excluding coronary artery disease .Basic Information of pa-tients were recorded ,ambulatory ECG monitoring was taken one day before and after PCI ,and turbulence onset (TO) ,turbulence slope (TS) ,turbulence slope time(TT)were calculated .Results The TO and TT in the Wellens’syndrome group were significantly higher than control group ( P < 0 .05) ,TS was significantly smaller than control group ( P < 0 .05) .Compared with what before revascularization ,the T0 ,TS and TT were improved in the first day after PCI of Wellens’syndrome group ( P < 0 .05) .Conclusions Revascularization can improve cardiac autonomic nervous function of the patients with Wellens’syndrome .
