Overview
ECG may show evidence of left ventricular hypertrophy, atrial fibrillation or premature ventricular complexes, or conduction delays, AV nodal block, or left bundle branch block may be observed.
Electrocardiogram
ECG may show evidence of the following findings:
- Left ventricular hypertrophy
- Atrial fibrillation or premature ventricular complexes
- Conduction delays, AV nodal block, or left bundle branch block may be observed.
Some studies have shown that left ventricular hypertrophy, altered heart rate, and anterolateral T-wave inversion can predict the risk of mortality or heart transplantation in dilated cardiomyopathy patients.[1][2]
