Key result
Implantable loop recorder captures asymptomatic polymorphic VT in Brugada syndrome, prompting ICD implantation.
Why the study?
Arrhythmic risk stratification and management of asymptomatic patients or those with syncope in Brugada syndrome remain challenging.
Case Report (n=1)
Implantable loop recorder monitoring in select asymptomatic patients with Brugada syndrome can identify unrecognized, life-threatening ventricular arrhythmias that warrant primary prevention ICD placement.
ILR may detect occult VT prompting ICD in asymptomatic Brugada; leaves open its role in routine risk stratification.
Brugada syndrome (BrS) is an inherited disease that heightens the risk of developing ventricular arrhythmias (VAs) and sudden cardiac death (SCD) in individuals with structurally normal hearts. Although patients presenting with aborted SCD or documented spontaneous sustained ventricular tachycardia (VT) have a clear indication for an implantable cardioverter-defibrillator (ICD),1 arrhythmic risk stratification and management of asymptomatic patients or those with syncope remain challenging. An implantable loop recorder (ILR) may have a significant role in this subgroup of patients.

Lima et al. (2024) conducted a case report in Asymptomatic Brugada syndrome (n=1). Implantable loop recorder (ILR) was evaluated on Detection of ventricular arrhythmias. An implantable loop recorder successfully detected a 9-second run of polymorphic ventricular tachycardia at 20 months in an asymptomatic patient with Brugada syndrome, prompting ICD implantation.
