以下是关于atrial flutter的详细解释：
Atrial flutter（心房扑动）是一种快速性心律失常，表现为心房内规则、快速的电活动，频率通常为250-350次/分钟。其机制多与心房内单一折返环有关，常见于器质性心脏病患者，如风湿性心脏病、冠心病、高血压性心脏病等，但也可能由非心脏因素（如甲状腺功能亢进、酒精中毒）引发。

"Atrial flutter" is a medical term used to describe an abnormal heart rhythm or arrhythmia. It is a type of supraventricular tachycardia (SVT) that occurs in the atria of the heart. In Chinese, "atrial flutter" can be translated as "心房扑动" (xīn fáng pū dòng).
Atrial flutter occurs when the electrical signals that regulate the heartbeat in the atria become chaotic and too rapid. This causes the atria to contract quickly and irregularly, which can lead to a variety of symptoms, such as palpitations, shortness of breath, chest pain, and fatigue. Atrial flutter is usually diagnosed by a doctor using an electrocardiogram (ECG) test.
Some synonyms for "atrial flutter" include "atrial tachycardia" and "atrial fibrillation." Atrial fibrillation is a similar condition, but it is characterized by a more chaotic and irregular heartbeat. Antonyms for atrial flutter would include a normal, regular heartbeat without any arrhythmia.
