Atrial fibrillation (AF)

心房颤动

英文解释

Atrial fibrillation (AF) is the most common arrhythmia encountered in the ICU. Preexisting AF is highly prevalent among older patients with chronic conditions who are at risk for critical illness, whereas new-onset AF can be triggered by accelerated atrial remodeling and arrhythmogenic triggers encountered during critical illness. The acute loss of atrial systole and onset of rapid ventricular rates that characterize new-onset AF often lead to decreased cardiac output and hemodynamic compromise.

中文解释

心房颤动 (AF) 是 ICU 最常见的心律失常。既往房颤在有危重疾病风险的慢性疾病老年患者中非常普遍，而新发房颤可由加速的心房重构和危重疾病期间遇到的心律失常诱发因素触发。新发房颤的特征是心房收缩的急性丧失和心室速率的快速发作，通常导致心排血量减少和血流动力学损害。
