生理性起搏的临床应用与心功能评价(附8例报告)

Physiological Pacing: Clinical Application and Cardiac Function Evaluation

为８例严重房室传导阻滞和病窦患者成功安置了生理性起搏器，心房按起搏和双腔起搏各４例，占我院三年来安置起搏器总数３８例的２１．１％．生理性起搏患者心功能显著优于非生理性起搏患者，每搏容量和心输出量分别增加２０％～７６％和２２％～７７％，为推广应用生理性起搏提供了依据。

Physiological pacemakers have been implanted successfully in 8 patients with severe AVB and SSS. There are 4 cases of AAI and 4 cases of DDD. The 8 cases of physiological pacing make up 21.1 % of all 38 pacemakers implanted in our hospital in recent 3 years. The cardiac function in patients with physiological pacing is much better than in patients with unphysiological pacing,the SV and CO are increased by 20-76% and 22-77% respectively. This work offers the base of wide application of physiological pacing.
