BRASH syndrome is characterized by bradycardia, renal failure, use of an atrioventricular nodal blocker (AVNB), shock, and hyperkalemia. These symptoms represent an ongoing vicious cycle in a patient with a low glomerular filtration rate taking an AVNB. Decreased clearance of the medication and hyperkalemia associated with renal failure synergize to cause bradycardia and hypoperfusion. This reaction causes renal function to worsen, thereby perpetuating the cycle of BRASH syndrome.
BRASH综合征的特征为心动过缓、肾衰竭、使用房室结阻滞剂(AVNB)、休克和高钾血症。这些症状在肾小球滤过率低且正在服用AVNB的患者中代表着一个持续的恶性循环。药物清除率降低以及与肾衰竭相关的高钾血症共同作用导致心动过缓和灌注不足。这种反应会使肾功能恶化,从而使BRASH综合征的循环持续下去。
