【摘要】 急危重症患者中房颤发生率较高,其发生机制主要有多子波折返与局灶激动、炎症反应、细胞内钙超载及交感神经激活等。房颤患者的抗凝治疗应放在首位,其次是当血流动力学不稳定时,立即电复律;当血流动力学稳定时,主要控制症状,多数房颤患者优先给予心率控制,而新发房颤患者及因可逆性原因出现的房颤患者宜行心律控制。更多还原

【Abstract】 There was high incidence of atrial fibrillation in critically ill patients.The mechanisms mainly include the occurrence of multiple wavelet reentry and focal activation,inflammation,intracellular calcium overload and sympathetic activation,etc.Anticoagulant therapy should be firstly considered in patients with atrial fibrillation.Subsequently,electrical conversion is needed in patients with hemodynamic instability.When the hemodynamics is stable,heart rate should be controlled firstly in most patients with atrial fibrillation in order to reduce the symptoms,but heart rhythm should be controlled for the patients with new onset atrial fibrillation or atrial fibrillation resulting from reversible reasons.更多还原
