Cardiovascular disease is detrimental to people’s health and economy of the family and government. To reduce the cardiovascular mortality rate, this article designs a novel wearable micro-intelligent electrocardiogram equipment. The device can be 105cm3 with a small size. Meanwhile, it can collect five-lead electrocardiograph (ECG) data and analyze and diagnose ECG data using pattern recognition support vector machine (SVM) algorithm, the cardiovascular disease therefore could be found early. This paper is meaningful and conducive to the research of relevant equipment for the cardiovascular disease.
