摘　　要：设计了一种多功能心脏电生理刺激记录仪,该设备以嵌入式系统为核心,前端电路包含除颤电压保护电路和静电防护电路,高压电路采用变压器耦合单端他激式MOS开关升压电路及高压稳压电路,用达林顿光耦开关进行脉冲控制,保证了脉冲输出波形的平稳。该设备可通过USB接口与计算机联机,同步实时采集并显示、存储体表十二导联及食管导联心电图;还集成了临床医师惯用的众多操作分析功能,有效优化了心脏电生理检查及记录工作流程。This paper introduces the design and implementation process of a multifunctional recorder for cardiac electrophysiology stimulation based on an embedded system. The front-end circuit which is composed of a defi brillation voltage protection circuit and an electrostatic protection circuit and highvoltage circuit which is composed of a boosted circuit of transformer-coupled and single-ended fl yback MOS switch and a high voltage regulator circuit are controlled with Darlington optocoupler switch to maintain the stable pulse output waveform. The isochronous and real-time collection, displaying and storage of 12 lead and esophageal lead electrocardiogram can be implemented through the connection between the computer and the recorder with the USB interface. The examination and recording process of cardiac electrophysiology has been optimized effectively with the recorder which has integrated various operation and analysis functions for clinician.
