基于FRDM-KL25Z及简单运放（LM324）设计出了一套小巧、低成本的心电监测装置。它不但能够结合上位机实时显示心电图而且能够将采集的心电信号储存于SD卡，用于24h心电监护，以备观察不同时间段心血管疾病的症状。(FRDM-KL25Z and simple operational amplifier (LM324) based on the designed ECG monitoring device with a set of small, low cost. It can not only combine with the real-time display of the host computer and can store the collected ECG signals in SD card for 24h ECG monitoring for the observation of the symptoms of cardiovascular diseases at different time periods. )
