WebIt is possible to diagnose pathological Q-waves (because the initial part of the QRS is not affected by the RBBB). Acute ischemia (ST-T changes) may also be judged as usual, despite the bundle branch block. Note that acute cor pulmonale with RBBB may cause large Q-waves in V1–V3, II, III and/or aVF.

Left ventricular hypertrophy. See a typical trace from the ECG library. R-wave in V6 greater than 25 mm. R-wave in V6 plus S-wave in V1 greater than 35 mm.
