生理性起搏器的应用

CLINICAL APPLICATION OF PHYSIOLOGICAL PACING

对17例生理性起搏器的患者进行临床疗效及随访观察。结果：在手术后3-45个月经随访未发现起搏器综合征；无1例再发心房纤颤；除1例扩张型心肌病患者死于急性左心衰外，其余历例患者心功能均较以前有明显改善，平均提高1－2级。生理性起搏的优点就是可维持正常的房室收缩顺序和心室激动顺序，保持较高的心排血量，避免了房颤的发生。心房起搏（AAI）应积极推广，使更多患者受益。

We observed the clinical and follow-up curative effecy of physiogical pacing for 17 patients.The ve-sults shown that during the postoperation and follow-up for 3-45 months there were no pacemaker syndrime, no atrial fibrillation vecurrence, and all patients cardial function iniproved except for one expansile myocardiosis patient who died of acute left heart failuve. on average, they improved 1-2 grade .The benefit of physiological pacing is that it can keep the normal A-V excitement sequence and normal A-V excittment sequence, that can maitain the cardiac output and can avoid the occur of atrial fibrillation. The technique is more fit for our province and should be recommended for further application.
