New ECG Criteria in Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy
Why the study?
Do newly proposed ECG criteria improve the identification of individuals affected by ARVD/C compared to current task force criteria?
Population
83 patients evaluated off drugs, including 50 index patients with proven ARVD/C and 33 patients with…

Implication
May support refining ARVD/C diagnosis with added ECG criteria; hypothesis-generating and requires prospective validation before practice change.
Structured PICO
Do newly proposed ECG criteria improve the identification of individuals affected by ARVD/C compared to current task force criteria?
P
Population
83 patients evaluated off drugs, including 50 index patients with proven ARVD/C (Task Force Criteria [TFC] ≥ 4 points) and 33 patients with probable ARVD/C (TFC 3 points; 21 index patients and 12 family members of proven ARVD/C patients).
I
Intervention
Newly proposed additional ECG criteria (prolonged terminal activation duration in V1-V3, VT with left bundle-branch block morphology and superior axis, and multiple VT morphologies)
C
Comparator
Current task force criteria (TFC) alone
O
Outcome
Proportion of probable ARVD/C patients fulfilling ARVD/C diagnosissurrogate
Adding newly proposed ECG criteria, such as prolonged terminal activation duration and specific VT morphologies, to current task force criteria significantly improves the diagnostic identification of ARVD/C.
