Introduction: Aluminum phosphide (ALP) is a highly toxic pesticide with no specific antidote which is widely used in developing countries. Upon ingestion, it releases phosphine gas, leading to severe metabolic derangements and cardiovascular collapse. Case Presentation: We report a case of a 28-year-old woman who presented to the emergency department following suicidal ingestion of aluminum phosphide. Shortly after admission, she developed a type 1 Brugada ECG pattern along with metabolic acidosis and cardiogenic shock. Despite intensive supportive care, including vasopressors, mechanical ventilation, and high-dose insulin therapy, the patient died on the fourth day due to refractory shock and acute respiratory distress syndrome (ARDS). Conclusions: This case illustrates a rare but critical manifestation of ALP poisoning: Brugada phenocopy. Clinicians should be aware of this ECG pattern in the context of toxic ingestion, as it may indicate underlying cardiac instability. Recognition of this ECG pattern in toxicological emergencies is essential for early diagnosis and intervention
