摘　　要：为了观察慢快综合征患者植入起搏器后对心功能,心房高频事件的影响,将植入具有自动化功能双腔起搏器的39例患者分为2组,A组起搏心率55次/分,B组起搏心率65次/分,术后1年内程控获取心房起搏百分比(Ap)、心室起搏百分比(Vp)、高频心房事件发生率(AHRE)、左房内径(LAD)、左室舒张末内径(LVEDD)、左室射血分数(LVEF)、血脑钠肽(BNP)。结果显示,A组相比B组Ap、Vp明显降低,LVEDD、LVEF明显改善,BNP明显降低,LAD、AHRE两组无差异。故对于慢快综合征患者,适当降低起搏频率可明显改善LVEDD、LVEF,使BNP明显降低。This is to observe the effect of cardiac function rapid atrial arrhythmia with bradycardia--tachycardia syndrome after the auto AV search algorithm. Thirty--nine patients implanted with two types of DDD/R pacemakers were investiga- ted in one year of follow--up study. The percent of atrial/ventricular pacing, atrial high frequence event, plasma brain na- triuretic peptide level and echocardiograph were recorded. The results is patients of low pacing rate 55 beats/min had a sig- nificant decrease in percentage of atrial/ventricular pacing3, 6 and 12months after implantation. The left ventricular end di- astolic diameter and the left ventricular ejection fraction was increased . The plasma BNP was decreased. The left atrial di- ameter and atrial high rate events were all identical. For patients with bradycardia--tachycardia syndrome, appropriate to reduce the pacing frequency can significantly improve left ventricular end diastolic diameter, left ventricular ejection fraction, the plasma brain natriuretic peptide decreased significantly, thus reducing the percentage of ventricular pacing.
