What are typical ECG findings in Arrhythmogenic Right Ventricular Dysplasia (ARVD)?

In Arrhythmogenic Right Ventricular Dysplasia (ARVD), characteristic ECG findings often include T-wave inversions, particularly in the V1 to V3 leads. This is significant because these T-wave inversions can reflect the underlying structural changes and electrical instability due to the replacement of right ventricular myocardium with fibrofatty tissue, which is a hallmark of ARVD.

The presence of T-wave inversions in the anterior leads is a diagnostic feature and is particularly important in the assessment of patients with a family history of sudden cardiac death or those presenting with ventricular arrhythmias. This specific finding helps differentiate ARVD from other cardiac conditions while also indicating an increased risk of arrhythmias, which is a critical aspect of managing this disease effectively.

Although other findings might occur in different cardiac conditions, T-wave inversion in the specified leads is especially noted in ARVD cases and plays a crucial role in guiding further investigation, risk stratification, and treatment planning.
