ECG markers may aid ARVD diagnosis stratified by RBBB; leaves open prospective validation before clinical use.
What is the diagnostic value of ECG markers for arrhythmogenic right ventricular dysplasia in the presence or absence of right bundle-branch block?
Specific ECG markers, such as T-wave inversion through V3 and an r'/s ratio in V1 <1, provide high diagnostic utility for ARVD depending on the presence and type of right bundle-branch block.
