心电图与心脏彩色多普勒超声在高血压心脏病中的诊断价值

Diagnostic value of ECG and heart color Doppler ultrasound on hypertensive heart disease

目的 探讨心电图与心脏彩色多普勒超声在高血压心脏病中的诊断价值. 方法 选择2013年4月至2014年3月高血压心脏病患者100例为观察组,对其分别行心电图、心脏彩色多普勒超声检查,比较其阳性检出率. 选取同期行健康体检的100例正常人群为对照组,比较两组相关指标. 结果 100例高血压心脏病患者中,心脏彩色多普勒超声检出率为73.0%,心电图检出率为49.0%,二者比较差异有统计学意义（ P〈0.01 ）. 另外,心脏彩色多普勒超声、心电图检查后均发现,两组左房内径、左房内径/主动脉根内径比较差异有统计学意义（P〈0.05）. 结论 心脏彩色多普勒超声相比心电图对高血压心脏病的敏感性、特异性更高,且左房内径/主动脉根内径可作为高血压心脏病诊断的特异指标.

Objective To investigate the diagnostic value of ECG and heart color Doppler ultra-sound on hypertensive heart disease .Methods From April 2013 to March 2014, 100 patients with hy-pertension heart disease were selected as the research group , the ECG, heart color ultrasound examina-tion were performed , the positive rate were compared .In 100 normal subjects and in the same period for health examination as control group , relevant indicators of the two groups were compared .Results A-mong the 100 cases of hypertensive heart disease , the detection rate of cardiac ultrasound was 73%, and 49%of the ECG 49%, the difference was significant （ P〈0.01 ） .In addition , after echocardiography , electrocardiogram were found , the left atrial diameter and left atrial diameter/aortic root diameter of the two groups were significantly different （ P〈0.05 ） .Conclusions The sensitivity , specificity of cardiac ultrasound is higher than ECG , and the left atrial diameter/aortic root diameter can be used as a specific index for the diagnosis of hypertensive heart disease .
