- W2355004105 abstract "Objective:To explore the value of the voltage of the S wave in lead aVR of electrocardiogram for diagnosis of left ventricular hypertrophy(LVH).Method:The electrocardiographic voltages of Rv5(6)+Sv1 and SaVR were measured in 60 cases of LVH confirmed by ultrasonic cardiogram(group A) and 40 cases without LVH(group B).The sensitivity,specificity and accuracy of the voltage criteria of Rv5(6)+Sv1,SaVR and the combination of both of them for diagnosis of LVH were calculated respectively.And the significance test(χ2) was made for them.Result:① In diagnosis of LVH with the voltage criteria of SaVR,a low sensitivity(36.6%),a high specificity(100%) and an accuracy of 62% were observed.② In diagnosis of LVH with the voltage criteria of Rv5(6)+Sv1,the sensitivity(58.3%) was higher than that of the voltage criteria of SaVR,with lower specificity(85%) and an accuracy of 69%.③ In diagnosis of LVH with the voltage criteria of Rv5(6)+Sv1 combined with SaVR,both of the sensitivity and accuracy were increased compared with each one of them,with a little decreased specificity.They were 73.3%,78% and 85% respectively.In diagnosis of LVH with the voltage criteria of RV5(6)+SV1 combined with SaVR,44 cases in group A and 6 cases in group B tallied with the ECG criteria.Conclusion:The voltage criteria of SaVR was possessed of practical value for diagnosis of LVH and was more ideal for this purpose when it was in combination with those of Rv5(6)+Sv1.Accordingly,the defect in diagnosis of LVH by a single sort of electrocardiographic voltage criteria might be remedied." @default.
