Goldberger's electrocardiographic triad in patients with echocardiographic severe left ventricular dysfunction.

In 1982, Goldberger described an electrocardiographic triad (SV1 or SV2 + RV5 or RV6 ≥ 3.5 mV, total QRS amplitude in each of the limb leads ≤ 0.8 mV, and R/S ratio < 1 in lead V4) that was 70% sensitive and > 90% specific for detecting severe left ventricular (LV) dysfunction.
