1、工作原理 Working Principle
中文:设备通过主机产生可控的矩形电脉冲,经食道电极或心内电极传递至心脏,在心动周期特定时刻给予电刺激,诱发心脏电活动改变;结合同步采集体表及食道导联心电图,观察心脏对电刺激的电生理应答,以此评估窦房结、房室结、旁路等心脏传导系统功能,完成电生理检查、诱发或终止心律失常、保护性起搏等临床操作。 English:The device generates controllable rectangular electrical pulses from the main unit, delivered to the heart via trans‑esophageal or intracardiac electrodes. Electrical stimuli are applied at specific moments of the cardiac cycle to induce changes in cardiac electrical activity. Synchronously acquire surface and esophageal‑lead ECG signals to observe cardiac electrophysiological responses, so as to evaluate the function of sinoatrial node, atrioventricular node, accessory pathways and other cardiac conduction systems for electrophysiological examination, induction/termination of arrhythmias and protective pacing。
