The diagnosis of Brugada phenocopy can be made if certain findings are present.

Criteria for the diagnosis of Brugada phenocopy – all of the following:

(1) presence of Type 1 or Type 2 Brugada pattern on the ECG

(2) presence of an identifiable underlying condition recognized as a cause for phenocopy

(3) absence of the Brugada pattern when condition resolves or is removed

(4) no reason to suspect congenital or concealed Brugada syndrome


Findings that make congenital Brugada syndrome unlikely:

(1) low pre-test probability of Brugada syndrome (based on family history and symptoms)

(2) negative provocative test for Brugada syndrome (not mandatory if there was surgical manipulation of the right ventricular outflow tract within the past 96 hours)

(3) negative genetic testing
