Abstract
Brugada phenocopy is considered when a Brugada-type ECG pattern is present but with a low likelihood of true Brugada syndrome, as indicated by negative family history, genetic testing, or provocative testing with drugs, or ECG normalization after the removal of precipitants. Brugada phenocopy has been reported due to various causes such as fever and electrolyte imbalance. We describe a 22-year-old man who presented with aluminum phosphide poisoning, resulting in severe metabolic acidosis, myocarditis, and profound myocardial depression. He developed transient Brugada-like ECG changes and multiorgan dysfunction, requiring intensive management, including mechanical ventilation and inotropes. Brugada phenocopy is a rare manifestation of aluminum phosphide-associated toxic myocarditis. After a week of treatment, there was a significant improvement in cardiac function and overall clinical status.
