摘　　要：介绍了一种用于持续静脉滴注声学造影剂定量心肌血流测量研究的、基于单片机的心脏程控触发装置,及其硬件电路设计和基于Keil C51的软件设计流程。该装置运行稳定可靠,为持续静脉滴注声学造影剂定量心肌血流测量研究提供了技术支持。This paper introduces a programming cardiac trigger apparatus used for the study of quantitative measurement of myocardial blood flow with myocardial contrast echocardiography. The design of hardware circuit based on MCU and the scheme of software based on Keil C51 are mainly discussed. With stable and reliable working, this apparatus provides a kind of technical support for the study of quantitative measurement of myocardial blood flow with continuous intravenous injection of sonicated microbubbles.
