The need for an easily generated, simulated QRS complex to facilitate preimplantation sensitivity testing of ventricular programmed pacemakers has led to the adoption of the sine squared waveform as the standard test pulse, by the Pacemaker Standards Subcommitte of the Association for the Advancement of Medical Instrumentation (AAMI). A simple circuit is presented that provides an accurate sine squared pulse with easily adjustable pulse width (base frequency). A suggested circuit for incorporating this sine squared pulse generator into a complete pacemaker test waveform generator/cardiac simulator is also presented.
为便于进行心室程控起搏器植入前的敏感性测试，需要一种易于生成的模拟QRS复合波，这导致美国医学仪器促进协会（AAMI）的起搏器标准小组委员会采用正弦平方波作为标准测试脉冲。本文介绍了一种简单电路，该电路可提供脉宽（基频）易于调节的精确正弦平方波脉冲。还介绍了一种将此正弦平方波脉冲发生器纳入完整起搏器测试波形发生器/心脏模拟器的建议电路。
