近年来,国内外对阵发性心房颤动诱发因素的研究提示,房性期前收缩是阵发性心房颤动的主要诱发因素之一,也是一个独立危险因素。在无心房颤动病史人群中房性期前收缩的发生率较高,且阵发性心房颤动患者的频发房性期前收缩并不总能诱发心房颤动,有必要分析房性期前收缩与心房颤动发作之间的相关性。对其相关心电图特征进行总结,对预防与控制阵发性心房颤动的发生具有重要意义。
In recent years, domestic and foreign research on the causes of paroxysmal atrial fibrillation prompted atrial contraction is the main predisposing factor of paroxysmal atrial fibrillation, but also an independent risk factor. Atrial fibrillation in the history of atrial premature atrial contraction in patients with a higher incidence, and paroxysmal atrial fibrillation in patients with frequent atrial contraction does not always induce atrial fibrillation, it is necessary to analyze the atrial contraction and Correlation between episodes of atrial fibrillation. To summarize the related ECG features is of great significance in preventing and controlling the occurrence of paroxysmal atrial fibrillation.
