摘　　要：心电图在临床诊断中应用广泛,心电图机只能即时记录心电信号而无法保存数据。本文将心电信号进行A/D转换,通过数据缓存,将数据送入USB数据传输接口,再和计算机等设备的USB接口相连,可以把心电信号数据输入到计算机等设备中,为心电信号的保存、分析、参数计算等提供了必要的手段。An electrocardiogram （ECG） is a clinical essential way in heart diseases diagnoses. Electrocardiograph is the instant record of ECG, but we cannot save ECG data through it. We put forward a new method in this paper to convert the analogy ECG signal to data and send the data to USB interface. That will bring us conveniences to introduce the data into computer. It also brings us a way to store the ECG data, to analyze the data and to calculate ECG characteristic parameters.
