Brugada syndrome (BS) may be "unmasked" by several pharmacological and/or physiological agents in an otherwise normal electrocardiogram. Once diagnosed the possibility of persistent ventricular tachycardia/fibrillation exists. Although this is treated with various antiarrhythmic agents, there remains a cohort of patients who fail to respond to conventional antiarrhythmic therapy therefore, amplifying the electrical storm. We report a case of a BS diagnosed via procainamide challenge, the resultant near fatal electrical storm aggravated by amiodarone and the eventual resolution with isoproterenol.
Brugada综合征(BS)在原本正常的心电图中可能会被多种药理和/或生理因素“诱发”。一旦确诊,就存在持续性室性心动过速/心室颤动的可能性。尽管使用了各种抗心律失常药物进行治疗,但仍有一部分患者对传统抗心律失常治疗无反应,从而加剧了电风暴。我们报告一例通过普鲁卡因胺激发试验诊断为BS的病例,胺碘酮加重了由此引发的近乎致命的电风暴,而异丙肾上腺素最终使其得到缓解。
