心房纤颤(简称房颤)是一种重要而常见的心律失常。绝大部分房颤患者都患有器质性心脏病。在一个患病的心脏出现了房颤,往往意味着心脏病变比较严重,心脏功能已减退到一定程度。根据病理生理学研究,房颤一旦出现,心脏排血量则比其正常心律时要降低30％左右,另在房颤出现后,在心房内易于形成血栓,从而增加了栓塞的潜在性危险,加之房颤患者往往心室率明显增快,易于促进心衰的出现。所以,对每个临床医生都应正确掌握房颤的诊断和治疗。临床实践证明,在适当的治疗下,有的房颤病人可以恢复窦性心律,心脏功能也相应的恢复。而另一些病人,房颤虽然未被纠正,但在适当的治疗下,心脏功能得以保持,可多年坚持工作。
Atrial fibrillation (atrial fibrillation) is an important and common arrhythmia. Most patients with AF suffer from organic heart disease. Atrial fibrillation in a diseased heart often means more serious heart disease and diminished heart function to some extent. According to the study of pathophysiology, once the occurrence of atrial fibrillation, cardiac output is lower than the normal cardiac rhythm of about 30%, and the other in the occurrence of atrial fibrillation, thrombosis in the atrium tends to form, thereby increasing the potential risk of embolism, combined with Atrial fibrillation patients often significantly increased ventricular rate, easy to promote the emergence of heart failure. Therefore, for each clinician should correctly grasp the diagnosis and treatment of atrial fibrillation. Clinical practice has proved that under the appropriate treatment, some patients with atrial fibrillation can restore sinus rhythm, heart function corresponding recovery. In other patients, atrial fibrillation is uncorrected, but with proper treatment, heart function can be maintained for many years.
