In this paper, Based on Rough sets, the algorithm of decision form reduction algorithm of Rough sets is studied, and is applied to the recognition of characteristic points in electrocardiogram. Finally the reduction rules are obtained.

• 本文在粗糙集理论的基础上，对粗集决策表的简化理论进行了研究，并将粗集决策表简化方法用于心电图特征点的识别，得到了心电图特征点识别的简化规则，利用这些简化规则可以有效地识别出心电图特征点。
