Abstract：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 defibrillation voltage protection circuit and an electrostatic protection circuit and high-voltage circuit which is composed of a boosted circuit of transformer-coupled and single-ended flyback 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.
