Results AT was induced spontaneously by atrial premature beats in 3 patients, and all other AT was inducible by atrial stimulation.
结果3例房速为房早诱发，其余均为心房电刺激诱发并可终止。
Results showed that long _ cycle leading to atrial fibrillation and flutter were mostly compensating period due to atrial premature beat or obviously sinus bradycardia.
结果显示：心房颤动或心房扑动发生前的长周期多见于房性期前收缩后代偿间歇及明显窦性心动过缓等心律失常；
These patients generally have many atrial premature beats noted on Holter monitoring.
通过动态心电图观察到这些患者普遍存在较多的心房早搏。
In them, sinus tachycardia, myocardial ischemia, atrial and ventricular premature beat were common.
其中以窦速、心肌缺血、房早和室早多见。
Conclusion: atrial overdrive can prevent AF, which may results from accelerating interatrial conduction, inhibiting atrial premature beat, eliminating sinus bradycardia and long short interval.
结论：心脏起搏抑制房颤发生的机制可能与快频率起搏加速心房内传导、抑制了房性期前收缩、消除了窦性心动过缓和心脏长短间歇有关。
The premature beats from lower right atrium and left atrial appendage showed higher inducibility of AF.
低位右心房及左心耳部位的期前兴奋易于诱发房颤。
Atrial fibrillation (Af) is the most commonly cardiac arrhythmia except premature ventricular beats. The therapy of Af with pacemaker is a valid method to the chronic and stubborn Af now.
