摘　　要：目的 探计心电图SaVR与Rv5＋Sv1联用诊断高血压左心室肥大的临床价值.方法 超声心动描记术诊断左心室肥大的高血压患者82例及无左心室肥大的健康人100例.测量SaVR和Rv5＋Sv1电压,计算SaVR、Rv5＋Sv1及两者联用诊断左心室肥大的敏感性、特异性及准确性.结果 SaVR诊断左心室肥大的敏感性低（45.0%）,特异性高（99.0%）,准确性为74.7%;而Sv5＋Sv1的敏感性（54.8%）较SaVR高,但特异性（85.0%）较低,准确性为71.4%;两者联用可明显提高诊断的敏感性及准确性（分别为87.8%、85.7%,均P〈0.01）.结论 SaVR与Rv5＋Sv1联用诊断高血压左心室肥大的敏感性和准确性较高.Objective To evaluate the clinical value of Saw combined with R5＋Sv1 in diagnosis of hypertensive left ventricular hypertrophy （LVH）. Methods The voltages of SaVR, and Rv5＋Sv1 were measured in 82 cases with hypertensive LVH determined by echocardiography and 100 healthy people. The sensitivity, specificity and accuracy of SaVR and Rv5＋Sv1, alone or in combination, for diagnosis of LVH were calculated. Results Both SaVR and Rv5＋Sv1 had lower sensitivity （45.0%, 54.8%）, higher specificity （99.0%, 85.0%） and moderate accuracy （ 74.7%, 71.4% ） in diagnosis of LVH. SaVR and Rv5＋Sv1 in combination significantly improved the sensitivity （87.8%） and accuracy （85.7%） （all P 〈 0.01）. Conclusion The sensitivity and accuracy of SaVR combined with Rv5＋Sv1 are higher in diagnosis of hypertensive LVH.
