摘　　要：目的　比较经食管心房调搏中两种刺激方法转复心房扑动的疗效。方法　将 83例AF患者分为连续频率递增刺激组 (n =5 6 )和猝发起搏组 (n =2 7) ,前者输出电压 2 0～ 30v,脉宽 10ms,调搏起始频率以高于AF频率 10次 min ,频率以 10次 min递增 ,直到AF中止或调搏频率达到 4 0 0次 min为止 ;后者输出电压至 30～ 35v ,脉宽 10ms,用S1S1刺激法 ,频率 5 0 0次 min ,起搏时间 1s。结果　两组患者有效率分别为 75 %和 88 9%。结论　采用猝发起搏可能是经食管心房调搏转复心房扑动中的较好的方法。Objective To compare the efficacy of two methods to converting Atrial Flutter by transesophageal atrial pacing in 83 patients.Methods 83 patients were divided into two groups.The one (56) was paced in increase of frequency by degrees.The other (27) was by burst pacing.The former: the pacing voltage set at 20～ 30 v ,the pulse width set at 10 ms, the rate set 10～ 20 bpm greater than the patient's atrial rate and increase every degree by 10 bpm.The pacing was terminated until AF was converted to sinus rhythm or until the pacing rate of 400 bpm was achieved.The latter: burst pacing, the voltage set at 30～ 35 v , the pulse width set at 10 ms, the rate set at 500 bpm, the continuance set at 1s.Results The effective rates were 75% and 88.9%, respectively.Conclusions Burst pacing may be a better approach to converting AF to sinus rhythm.
