心房起搏心房感知抑制型起搏(AAI),能保持房室同步舒缩,故属生理性起搏。AAI 与日前临床上多用的心室起搏心室感知抑制型起搏(VVI)比较有许多优越性。我院自1989年5月以来已安置了4例,病人情况良好,摘要报告如下.病例选择:临床和电生理检查确诊为病态窦房给综合征(SSS)有晕厥症状需植入起搏器者;房室传导功能正常(心电图和希氏束电图均正常,心房起搏时文氏阻滞点>130bpm)且无快速心律失常者。随访结果:均呈现良好的房室顺序收缩的血动力学效益,晕厥等症状消失,无心房电极脱位和起搏综合征等合并症。 Atrial Pacing Atrial Sense Suppression Pacing (AAI), can maintain atrioventricular synchronized Shu, it is physiological pacing. AAI has many advantages over ventricular pacing and ventricular-aware inhibitory pacing (VVI). Four cases have been placed in our hospital since May 1989. The patient is in good condition and the summary is reported as follows: Case Selection: Pacemaker Implantation of Pacemaker with Clinical and Electrophysiological Diagnosis of Sick Syndrome in Sick Sinus Syndrome (SSS) ; Atrioventricular conduction function is normal (normal ECG and His bundle test, atrial pacing Wen’s block point> 130bpm) and no tachyarrhythmia. Follow-up results: Both showed good hemodynamic benefit of atrioventricular contractions, disappearance of symptoms such as syncope, absence of atrial electrode dislocation and pacing syndrome.
