超声心动图联合心电图对提高心尖肥厚型心肌病患者临床诊断效果评价

Evaluation of Echocardiography Combined with ECG in Improving Clinical Diagnosis of Apical Hypertrophic Cardiomyopathy

目的探讨超声心动图联合心电图对提高心尖肥厚型心肌病患者临床诊断效果评价。方法便利选择2018年1—12月收治的50例心尖肥厚型心肌病患者(研究组)与50例常规体检自愿者(对照组)纳入研究,均实施超声心动图联合心电图检查;观察比较两组的常规超声心动图参数,心电图指标。结果研究组左心房收缩期内径(40.50±4.33)mm、左心室心尖部最大厚度(17.55±2.35)mm、ST段下移(0.25±0.13)mV、左胸导联R波振幅(2.83±0.50)mV、T波倒置幅度(0.81±0.50)mV高于对照组,差异有统计学意义(P<0.05);研究组二尖瓣瓣环e'(4.95±1.35)及侧壁e'(8.50±2.76)均低于对照组,差异有统计学意义(t=7.97、2.65,P<0.05)。结论超声心动图联合心电图检查方法可提高心尖肥厚型心肌病的临床诊断效果。

Objective To evaluate the effect of echocardiography combined with electrocardiogram in improving the clinical diagnosis of apical hypertrophic cardiomyopathy.Methods From January to December 2018,50 patients with apical hypertrophic cardiomyopathy(study group)and 50 volunteers(control group)were convenient enrolled in the study.Echocardiography combined with electrocardiogram was performed,and the parameters of routine echocardiography and electrocardiogram were observed and compared between the two groups.Results The systolic diameter of left atrium in the study group(40.50±4.33)mm,was significantly thicker than that in the control group(17.55±2.35)mm,ST(0.25±0.13)mv,R wave amplitude of left chest lead(2.83±0.50)mv,T wave inversion(0.81±0.50)mV,and the difference was statistically significant(P<0.05).The mitral valve annulus e’(4.95±1.35)and sidewall e’(8.50±2.76)in the study group were lower than those in the control group,and the difference was statistically significant(t=7.97,2.65,P<0.05).Conclusion Echocardiography combined with electrocardiogram can improve the clinical diagnosis of apical hypertrophic cardiomyopathy.
