Transient Brugada Like after Scorpion Sting: An Unexpected Connection

Introduction: Brugada syndrome was described in 1992 as a new clinical and electrocardiographic syndrome involving susceptibility to ventricular arrhythmias and sudden cardiac death in patients without obvious structural heart disease. Brugada phenocopy (BrP) is an evolving term for Brugada-like ECG patterns due to reversible causes. In this article, we will illustrate the case of a patient presenting with a transient Brugada pattern following a scorpion sting. Case Report: A 65-year-old woman with age and menopause as cardiovascular risk factors, but no notable medical history, presented to the emergency department with atypical chest pain five hours after a scorpion sting. She had no associated symptoms such as dyspnoea, syncope, or palpitations, nor a personal or family history of sudden death. On admission, she was conscious, hemodynamically stable, normotensive, and tachycardic, with no signs of heart failure. Her ECG showed a 2 mm elevation at the J point and an inverted T wave in V1 and V2, indicating a Brugada pattern. She was admitted to the ICU for close monitoring. An echocardiogram revealed normal left and right ventricular function. Lab tests showed negative troponins, a normal blood ionogram, and normal renal and hepatic function. The Brugada pattern resolved within a few hours, and the patient remained stable. Discussion and Conclusion: Our case highlights the importance of conducting a thorough medical history to rule out the presence of arrhythmia, syncope, or a family history of sudden cardiac death in similar situations. If the history raises concerns, cardiological follow-up is essential to investigate the possibility of Brugada syndrome. Performing a follow-up ECG at discharge is beneficial to confirm the reversibility of the findings. This distinction is crucial as it helps differentiate between Brugada syndrome and the Brugada pattern, the latter being a condition that may occur in patients with scorpion stings or other triggers.
