Terminological clarification of Brugada Phenocopy, Brugada Syndrome, and the Brugada ECG pattern

<p>Suspected hyponatremia-induced Brugada phenocopy</p>

“…As per Anselm et al’s BrP systematic diagnostic criteria, it is likely that our patient did display a type 1, class B, hyponatremia-induced BrP (as drug challenge was not performed) which subsequently resolved after normalization of the electrolyte derangement 31,32. It is imperative to note that while BrS and BrP have identical patterns in precordial leads V 1 to V 3, patients with BrP have an identifiable underlying condition that elicits these patterns which normalize upon resolution.…”

“…Furthermore, BrS possesses a high clinical pretest probability of true congenital BrS, whereas conversely, BrP has a low pretest probability based on symptomatology and history. Significantly, patients with BrP have a negative provocative challenge with procainamide, flecainide, or ajmaline, while patients with true congenital BrS have a positive provocative challenge 31…”
