ELECTROCARDIOGRAPHIC SIGNS OF RIGHT VENTRICULAR OVERLOAD
The following abnormalities are regarded as suggestive of right ventricular (RV) overload: S-wave in lead I and Q-wave in lead III each of amplitude > 1.5 mm, with or without T-wave inversion in lead III; S-waves in lead I, II, and III each of amplitude > 1.5 mm; T-wave inversion in right precordial leads; transient right bundle branch block; pseudoinfarction. If any of the above abnormalities are present in electrocardiograms taken prior to the onset of symptoms, they are disregarded.
