摘　　要：目前关于R波检测的算法有很多,但大多运算比较复杂且存在浮点运算,运算量比较大。使得这些算法不适合在那些不具在有浮点运算功能的MCU(microprocessor controlunit)上运行。提出一种简单快速实时R波检测算法,其绝大部分是加减运算,不但避免了浮点运算,而且还能滤除50Hz的工频干扰,基线漂移和低频高频干扰,同时还具有对心电信号进行差分并将R波波峰转换成正负极值对的功能。实验结果表明,所提出的R波检测算法具有较好的鲁棒性,能够较好地抑止或消除基线漂移、高频干扰等外部因素对R波检测产生的影响。At present, most of the R wave detection algorithms cannot be applied on the MCU without float operation because many of them are very complicated and focus on the float operations. A new simple fast realtime R wave detection algorithm is presented in detail to avoid the disadvantages of most R wave detection algorithms. The new algorithm can remove or restrain the noise of 50 Hz, baseline drift and high or low frequency noise, can transform R wave to a couple of extremums. Additions and subtractions are the primary operations in the algorithm. Test results show that the R wave detection algorithm is robust, can remove or restrain the influence of extem noise such as baseline drift, high frequency, low frequency.
