- W2441632763 abstract "Cardiomegaly is one of the commonest findings encountered in daily clinical practice, and its differential diagnosis is a common clinical problem. There are many electrocardiological (ECG) criteria known for left ventricular hypertrophy (LVH), but its limitations have also been suggested. We evaluated 102 patients fulfilling the ECG criteria of precordial and limb lead for LVH with echocardiographic findings as a gold standard. Among these 102 patients, the echocardiogram revealed 38 subjects with LVH, 26 subjects with left ventricular dilatation (LVD), 7 subjects with both findings, and 31 subjects with neither findings. Precordial criteria such as SV1+RV5 or RV6 > 30 mm, SV1 or SV2+RV5 > 35 mm, R+S > 40 mm, SV1 or SV2+RV5 or RV6 > 35 mm, SV2+RV4 or RV5 > 35 mm, high in sensitivity and low in specificity for LVD and LVH, are appropriate for screening LVD and LVH. Cornell limb lead criterion, SV3+RaVL > 28 mm (male), SV3+RaVL > 20 mm (female), high in sensitivity and specificity only for LVH, is the best elecrocardiographic criterion to evaluate LVH. Precordial and limb lead criteria such as R> 13 mm, RaVL > 12 mm, RaVF > 20 mm, onset of intrinsicoid deflection in V5 or V6> 0.05 sec, left axis deviation -30 degrees to -90 degrees, low in sensitivity, and high in specificity, are useful to rule out LVH and/or LVD. Our findings suggest LVD and LVH can be evaluated by ECG, but similar sensitivity and specificity for both LVH and LVD makes separation of LVH from LVD unattainable." @default.
