Brugada syndrome is an arrhythmogenic disease characterized by a pattern of ST segment elevation in the right precordial leads on an electrocardiogram with an increased risk of sudden cardiac death. It is primarily reported in adults with limited data about the prevalence, prognosis, and long-term management in children. We describe a 10-year-old boy with a family history of sudden cardiac death, who had near syncope associated with a febrile illness. A screening electrocardiogram revealed ST segment elevation in the right precordial leads consistent with Type-1 Brugada syndrome. An electrocardiogram after recovery from his illness showed Type-2 "saddle-back" ST segment changes. An echocardiogram and a cardiac magnetic resonance imaging revealed a normal heart without myocardial fibrofatty infiltration, scar, or ischemia. A tilt-table test was negative. Implantable cardioverter-defibrillator placement remains the only effective treatment for patients with symptomatic Brugada syndrome; however, risk stratification of asymptomatic patients continues to remain a challenge. Although some investigators have reported the use of electrophysiological studies for distinguishing between high and low risk patients with Brugada syndrome, there are no precise predictors of risk for sudden cardiac death in pediatric patients. After careful discussion, this patient was considered intermediate to high risk for sudden cardiac death and had successful implantation of a transvenous defibrillator. Although Brugada syndrome is a rare diagnosis in the pediatric population, such patients should be referred for further evaluation and management.
Brugada综合征是一种致心律失常性疾病,其特征为心电图上右胸前导联出现ST段抬高模式,且心脏性猝死风险增加。该病主要在成人中报道,关于儿童的患病率、预后及长期管理的数据有限。我们描述了一名有心脏性猝死家族史的10岁男孩,他在发热性疾病期间出现近乎晕厥的症状。筛查心电图显示右胸前导联ST段抬高,符合1型Brugada综合征。病愈后的心电图显示为2型“马鞍形”ST段改变。超声心动图和心脏磁共振成像显示心脏正常,无心肌脂肪浸润、瘢痕或缺血。倾斜试验结果为阴性。对于有症状的Brugada综合征患者,植入式心脏复律除颤器仍是唯一有效的治疗方法;然而,无症状患者的风险分层仍然是一个挑战。尽管一些研究人员报告了使用电生理检查来区分Brugada综合征高危和低危患者,但在儿科患者中尚无心脏性猝死风险的精确预测指标。经过仔细讨论,该患者被认为心脏性猝死风险为中到高危,并成功植入了经静脉除颤器。尽管Brugada综合征在儿科人群中是一种罕见的诊断,但此类患者应转诊进行进一步评估和管理。
