本文报导应用超声心动图观察150例心房颤动病人的左房大小。结果表明:(1)左房内径<40mm,大多为窦性心律;40—55mm,呈发作性或持久性房颤;>55mm,常呈持久性房颤。然而,孤立性房颤病人多呈发作性,其左房内径均在正常范围。(2)左房内径>45mm,房颤持续1年以上者,除颤难以奏效,但还须考虑到房颤的病因和病人的年龄,某些左房内径正常者,即使房颤持续时间较长,仍可试以电击复律并积极治疗原发病。
This article reports the application of echocardiography observed 150 cases of atrial fibrillation in patients with left atrial size. The results showed that: (1) left atrial diameter <40mm, mostly sinus rhythm; 40-55mm, was episodic or persistent atrial fibrillation;> 55mm, often persistent atrial fibrillation. However, patients with isolated atrial fibrillation are mostly seizures, the left atrial diameter are in the normal range. (2) left atrial diameter> 45mm, atrial fibrillation for more than 1 year, defibrillation difficult to work, but must also take into account the cause of atrial fibrillation and the patient’s age, some left atrial normal diameter, even if the duration of atrial fibrillation Long, can still try to shock cardioversion and active treatment of the primary disease.
