摘　　要：目的观察急性冠脉综合征(ACS)合并完全性左束支阻滞(CLBBB)患者心率减速力(DC)、连续心率减速力(DRs)、心率变异性(HRV)的变化。方法比较40例ACS合并CLBBB患者(观察组)及42例ACS患者(对照组)DC、DRs、HRV,观察ACS合并CLBBB患者随访期间主要不良心血管事件(MACE)发生情况。结果观察组DC、DRs及HRV显著低于对照组(P<0.01),而高危患者比例明显高于对照组(P<0.05)。ACS合并CLBBB高危患者MACE发生率明显高于低危和中危患者(P<0.05)。结论DC、DRs、HRV可用于评估ACS合并CLBBB患者的风险及预后。Objective To observe the changes of heart rate deceleration capacity(DC),deceleration runs(DRs)and variability(HRV)in patients with acute coronary syndrome(ACS)and complete left bundle branch block(CLBBB).Methods DC,DRs and HRV were compared between 40 ACS patients with CLBBB(observation group)and 42 ACS patients(control group).The major adverse cardiovascular events(MACEs)were followed up in observation group.Results Compared with control group,DC,DRs and HRV were lower(P<0.01),while high risk cases were higher(P<0.05)in observation group.MACEs were more common in high risk cases than in low/moderate risk cases of observation group(P<0.05).Conclusions DC,DRs and HRV are useful in assessing the risk and prognosis of ACS patients with CLBBB.
