Nowadays we have various electrocardiography monitors from different manufactures in the market. Since the data format of one manufacture’s electrocardiography monitor is different from, and not compatible with the other, the way to unified management of electrocardiography data is blocked with so many obstacles. To improve the current situation above, this paper proposes a method, which is parsing of various electrocardiography data and converting from one to another. Thus, the unified management of electrocardiography can be accomplished.
