抗心动过速起搏器是新发展的起搏治疗技术。本文首次报道我院对两例患者使用Telectronics公司PASAR4171起搏器,(程控自动扫描复律起搏器),它可判断心动过速,自动发放1～7个脉冲,作期前刺激。如心动过速不终止,则反复发放,而且配对间期逐渐缩短,形成扫描刺激,以终止心动过速。 Anti-tachycardia pacemaker is a newly developed pacing therapy technology. This paper reports for the first time in our hospital the two patients using Telectronics PASAR4171 pacemaker, (programmable automatic pacemaker pacemaker), which can determine tachycardia, automatically release 1 to 7 pulses, pre-stimulation. If the tachycardia does not terminate, then repeatedly distributed, and the pairing interval gradually shortened to form a scanning stimulus to terminate tachycardia.
