目的探索超声心动图和心电图在高血压性心脏病诊断中的临床应用效果。方法选择2013年6月至2016年6月期间收治的180例疑似高血压性心脏病患者为此次研究对象,进行随机化分组,并分为两组,对两组患者分别采用心电图和超声心动图诊断,每组患者各有90例。结果超声心动图对左室肥厚患者的诊断正确率为98.46%,对左房增大患者诊断正确率为98.04%,对左室增大患者诊断正确率为90.91%,同时超声心动图误诊率、漏诊率、特异性、敏感性分别为10.00%、1.25%、90.00%、98.75%,而心电图对左室肥厚患者的诊断正确率为64.62%,对左房增大患者诊断正确率为58.00%,对左室增大患者诊断正确率为62.50%,同时心电图误诊率、漏诊率、特异性、敏感性分别为33.33%、32.05%、66.67%、67.95%,两组对此存在差异性(P<0.05)。结论超声心动图在高血压性心脏病患者中更具有诊断意义。
Objective To explore the clinical application of echocardiography and electrocardiogram in the diagnosis of hypertensive heart disease. Methods One hundred and eighty patients with suspected hypertensive heart disease admitted between June 2013 and June 2016 were selected as the study subjects and randomly divided into two groups. ECG and echocardiography were performed on the two groups Figure diagnosis, each group of 90 patients each. Results The diagnostic accuracy of echocardiography was 98.46% in patients with left ventricular hypertrophy, 98.04% in patients with enlarged left atrium, and 90.91% in patients with left ventricular enlargement. The echocardiographic misdiagnosis rate, The rate of misdiagnosis, specificity and sensitivity were 10.00%, 1.25%, 90.00% and 98.75%, respectively. The correct rate of electrocardiogram in diagnosing left ventricular hypertrophy was 64.62%, and the correct rate of diagnosing left atrium was 58.00% The diagnostic accuracy rate of patients with left ventricular enlargement was 62.50%, meanwhile the misdiagnosis rate, misdiagnosis rate, specificity and sensitivity of electrocardiogram were 33.33%, 32.05%, 66.67% and 67.95%, respectively (P < 0.05). Conclusion Echocardiography is more diagnostic in patients with hypertensive heart disease.
