48例AAI起搏临床随访观察

Follow-up Observation of 48 Cases of AAI Pacing

AAI起搏器是近年来逐渐引起国内外重视的一种生理性起搏,我院自1993年1月～1998年9月共安置48例此种起搏器,均为病态窦房结综合征(SSS)患者。其中单纯窦缓、窦停30例,慢快综合征18例。安置后临床症状均有不同程度改善。仅1例发生早期电极脱位,1例1年后发生Ⅱ度AVB。结论:AAI起搏方式具有简单、经济、实用的特点,并可预防和减少阵发房颤的发生,不会发生起搏器综合征,是一种良好的生理起搏。

Methods:Since January 1993 to December 1998,48 patients with sick sinus syndrome had received atrial pacing-atrial sensin-inhibited (AAI) pacing system. In them,30 patients had sinus bradycardia and sinus arrest,and 18 patients had bra-dy-tachycardia syndrome.Results:Follow up 6 to 61 months (mean 25 months) all patients had improvement in clinical symptom,only 1 case had lead displacement in early phase and 1 case had Ⅱ°atrioventricular block. Conclusion:AAI pacemaker has advantages of simplicity and reliability, which can prevent the occurrence of proximal atrial fibrillation and avoid complication of pacemaker syndrome. AAI pacemaker is a better physiological pacing instrument.
