摘　　要：目的:探究老年非ST段抬高型心肌梗死(NSTEMI)合并右束支阻滞(RBBB)患者的心电图及临床特征。方法:选取吉安县人民医院2021年6月—2022年6月收治的40例NSTEMI合并RBBB老年患者为观察组,另选择40例单纯NSTEMI老年患者为对照组,对两组患者均进行心电图检查。比较两组ST-T改变、QRS时间、Tp-Te间期、心率及T波异常情况,另分析两组患者心功能Killip分级和不良心血管事件发生情况。结果:两组ST段压低发生率及T波异常发生率比较,差异均无统计学意义(P>0.05)。相比于对照组,观察组QRS时间、Tp-Te间期均更长,心率更快,差异均有统计学意义(P<0.05)。相比于对照组,观察组Killip 2级占比更低,差异有统计学意义(P<0.05)。相比于对照组,观察组不良心血管事件发生率更高,差异有统计学意义(P<0.05)。结论:老年NSTEMI合并RBBB患者ST段明显压低,QRS时间及Tp-Te间期均更长,且具有较快的心率,表明此类患者心功能不全,病情危重,预后一般,临床上需高度重视。Objective:To investigate the electrocardiogram and clinical characteristics of elderly patients with non-ST-segment elevation myocardial infarction(NSTEMI)complicated with right bundle branch block(RBBB).Method:A total of 40 elderly patients with NSTEMI complicated with RBBB admitted to Ji’an County People's Hospital from June 2021 to June 2022 were selected as the observation group,and another 40 elderly patients with NSTEMI alone were selected as the control group.Electrocardiogram examination was performed in both groups.ST-T changes,QRS time,Tp-Te interval,heart rate and T wave abnormality were compared between the two groups,and Killip grade of cardiac function and adverse cardiovascular events were analyzed between the two groups.Result:There were no statistical significances in the incidences of ST segment depression and T wave abnormality between the two groups(P>0.05).Compared with control group,QRS time and Tp-Te interval in observation group were longer and heart rate in observation was faster,the differences were statistically significant(P<0.05).Compared with the control group,the proportion of Killip 2 in the observation group was higher,the difference was statistically significant(P<0.05).Compared with the control group,the incidence of adverse cardiovascular events in the observation group was higher,the difference was statistically significant(P<0.05).Conclusion:Elderly patients with NSTEMI complicated with RBBB have significant ST segment depression,longer QRS time and Tp-Te interval,and faster heart rate,indicating that these patients have cardiac insufficiency,critical condition and general prognosis,and need to be highly regarded clinically.
