Electrocardiographic ARVD Risk Score for the Diagnosis of ARVD

Electrocardiographic ARVD/C Risk Score
ECG Characteristic	Points
Anterior T‐wave inversions (V1–V3) in sinus rhythm	3
VT/PVC
Lead 1 QRS duration >120 ms	2
QRS notching (multiple leads)	2
V5 transition or later	1
Maximum total	8

A score of 5 or greater correctly distinguishes ARVD from idiopathic VT 93% of the time (sensitivity of 84%, specificity of 100%, positive predictive value of 100%, negative predictive value of 91%).4
