Signal-Averaged ECG in the Diagnostic Workup for Arrhythmogenic Cardiomyopathy : Insights From the Nordic ARVC Registry
BACKGROUND: The diagnostic role of signal-averaged ECG (SAECG) in arrhythmogenic right ventricular cardiomyopathy (ARVC) has lately been questioned. We assessed the value of SAECG-derived late ventricular potentials (LP) in ARVC diagnosis and its association with disease manifestations.METHODS AND RESULTS: Patients with definite ARVC diagnosis or genotype-positive family members who underwent SAEC
