A personal computer with a digital-to-analog converter is used as an electrocardiogram simulator. A TurboPascal procedure, given the heart rate, rhythm, and ST segment levels, generates the voltages for Leads II and V5. A simple circuit reduces the voltages to the physiologic range and smoothes the waveforms, removing the staircase effects of digitalization. The procedure can be manually controlled using a software interface or driven by other programs for use in a full-scale operating room simulator.
一台带有数模转换器的个人计算机被用作心电图模拟器。一个TurboPascal程序，根据心率、心律和ST段水平，生成导联II和V5的电压。一个简单的电路将电压降低到生理范围并平滑波形，消除数字化的阶梯效应。该程序可以通过软件界面手动控制，也可以由其他程序驱动，用于全尺寸手术室模拟器。
