Abstract

Background: Brugada phenocopy (BrP) refers to reversible electrocardiographic (ECG) patterns that mimic Brugada syndrome (BrS) in the absence of an underlying congenital channelopathy. Fever is a recognized trigger that can unmask Brugada-like ECG changes, particularly in older adults. Case Report: An 83-year-old man presented to the emergency department with fever and respiratory symptoms. Initial ECG demonstrated a type 1 Brugada-like pattern. Laboratory evaluation revealed inflammatory markers consistent with infection. Following antipyretic treatment and normalization of body temperature, repeat ECG showed complete resolution of the Brugada-like changes. The patient was monitored in the cardiology unit without arrhythmic events. Conclusion: This case highlights fever as a reversible cause of Brugada phenocopy in an elderly patient. Prompt recognition and treatment of the underlying trigger are essential to avoid unnecessary invasive interventions such as implantable cardioverter-defibrillator implantation.

Özet

Arka Plan: Brugada fenokopisi (BrP), altta yatan doğuştan gelen bir kanalopatinin yokluğunda Brugada sendromunu (BrS) taklit eden geri dönüşümlü elektrokardiyografik (EKG) paternleri ifade eder. Ateş, özellikle yaşlı yetişkinlerde Brugada benzeri EKG değişikliklerini ortaya çıkarabilen bilinen bir tetikleyicidir. Vaka Raporu: 83 yaşında bir erkek hasta, ateş ve solunum semptomlarıyla acil servise başvurdu. İlk EKG'de tip 1 Brugada benzeri bir patern görüldü. Laboratuvar değerlendirmesi, enfeksiyonla uyumlu inflamatuar belirteçler ortaya koydu. Ateş düşürücü tedavi ve vücut sıcaklığının normale dönmesinin ardından, tekrarlanan EKG'de Brugada benzeri değişikliklerin tamamen düzeldiği görüldü. Hasta, aritmi olayları olmaksızın kardiyoloji ünitesinde izlendi. Sonuç: Bu vaka, yaşlı bir hastada Brugada fenokopisinin geri dönüşümlü bir nedeni olarak ateşi vurgulamaktadır. Gereksiz invaziv müdahalelerden (örneğin implante edilebilir kardiyoverter-defibrilatör implantasyonu) kaçınmak için altta yatan tetikleyicinin hızlı bir şekilde tanınması ve tedavi edilmesi şarttır.
