Describe and interpret this ECG
ECG ANSWER and INTERPRETATION
This is an ECG example of dilated cardiomyopathy demonstrating signs of enlargement of all four cardiac chambers:
- There is marked LVH with very deep S waves in V2-4.
- Right axis deviation suggests associated RV enlargement (= biventricular enlargement).
- Evidence of left atrial enlargement (deep, wide terminal portion of the P wave in V1).
- Peaked P waves in lead II suggestive of right atrial enlargement (~ 2.5mm in height).
This patient had four-chamber dilatation on echocardiography with severe congestive cardiac failure (awaiting cardiac transplantation).

It’s possible see still two signs of RAE: Sodi-Pallares sign – qR (in this case qRs) in V1 (normal is rS); and Peñaloza-Tranchesi sign – fast change QRS shape V1 to V2, little in the first and normal in the last one.
