Key result
Severe methanol intoxication induced a Brugada type 1 ECG pattern that completely resolved upon correction of hyperkalaemia and metabolic acidosis.
Why the study?
Brugada phenocopies present with Brugada ECG patterns associated with identifiable conditions, but no published case reports had described Brugada phenocopy in association with methanol intoxication.

Methanol intoxication with severe metabolic acidosis and hyperkalaemia can induce a Brugada phenocopy that resolves upon correction of the metabolic derangements.
Methanol intoxication may induce reversible Brugada phenocopy; extends differential but leaves open prospective validation.
Brugada phenocopies (BrP) are clinical entities that present with an ECG pattern identical to either the type 1 or type 2 Brugada pattern without true congenital Brugada syndrome. This ECG pattern is associated with an identifiable condition and normalizes upon resolution or treatment of the underlying cause. We present a case of a 54-year-old man with extreme metabolic acidosis, hyperkalaemia and a Brugada type 1 ECG pattern in the setting of a suicidal methanol (MeOH) poisoning. Upon correction of these metabolic derangements with bicarbonate infusions and continuous veno-venous haemodiafiltration (CVVH), the Brugada type 1 ECG pattern normalized. Unfortunately, the patient developed signs of cerebral herniation followed by brain death and died on the first day of ICU admission. LEARNING POINTS: Brugada-like ECG patterns are described in several metabolic conditions such as extreme hyperglycaemia, glucose/insulin challenge, isolated hyperkalaemia or in association with hyponatraemia and acidosis.Until now, there have been no published case reports of BrP in association with methanol intoxication.Correction of hyperkalaemia and acidosis and specific therapy for methanol intoxication leads to a complete resolution of a Brugada type 1 ECG pattern.

Jesús et al. (2020) conducted a case report in Methanol intoxication with Brugada phenocopy (n=1). Methanol intoxication was evaluated on Resolution of Brugada type 1 ECG pattern. Severe methanol intoxication induced a Brugada type 1 ECG pattern that completely resolved upon correction of hyperkalaemia and metabolic acidosis.
