基于USB接口的虚拟心电监护仪设计

摘要

Heart disease is one of the major diseases that seriously threat to human's health and life. ECG monitoring system can have timely access to patients' ECG information and find ECG abnormalities. Taking appropriate treatment measures timely is one of the most effective methods to reduce heart disease. However most ECG equitments are used in hospital and it's very expensive. Developing a low-cost ECG monitor, making convenient to people who need ECG monitor at home will have a large market demand and important research significance.%心脏病是严重威胁人类健康和生命的主要疾病之一.心电监测系统能及时获取患者的心电信息,发现心电异常情况,及时采取相应处理措施,是降低心脏病死亡率有效手段之一.而多数心电监护设备都在医院使用,成本高.开发一种低成本心电监测仪器,使一些有心电方面监测需求的人能在家中检测心电情况,将具有巨大的市场需求和重要的研究意义.
