摘　　要：目的探讨肌袖性房性心律失常的动态心电图（DEC）特征。方法对比8例肌袖性房性心律失常与10例非肌袖性房性心律失常患者的临床和DEC特点。结果肌袖性房性心律失常有频发房性期前收缩，短阵房性心动过速，心房扑动，均发生短阵心房颤动，发作时间为2～15min不等，诱发心房颤动的房性期前收缩联律间期（0．24±0．03）s，明显短于对照组房性期前收缩联律间期（0．34±0．05）s（P〈0．01）。结论肌袖性房性心律失常的DEC中窦性心律、房性心动过速、心房扑动、心房颤动交替转换，诱发心房颤动发作的房性期前收缩联律间期短，几乎均呈“P-on-T”现象。Objective To analyze the characters of dynamic electrocardiography recorded in atrial arrhythmia related to muscle sleeve. Methods Clinical features and dynamic electrocardiographies for 8 patients with complex Atrial Arrhythmia re lated to muscle sleeve and 10 patients with complex atrial arrhythmia unrelated to muscle sleeve were analyzed. Results There were frequent atrial premature beats and atrial flutter（AF） in the eight patients, all of them occurred atrial fibrillation（M）. The mean duration of their atrial fibrillation was 2-15 rains, The intervals of atrial premature beats related muscle sleeve AF shorter than those of comparison group（ P 〈 0.01）. Conclusion Frequent transition of sinus beats , Af and AF can be seen in dynamic electrocardiography recorded in atrial arrhythmia related to muscle sleeve. They are always accompanied with frequent atrial premature beats, The interval of atrial premature beats related to Af is shorter, Af is mostly triggered by ＂P-on-T＂ atrial premature beats.
