摘　　要：在心率变异分析中,不仅要可靠地检测出 R 波,而且要对 R 波的峰值点进行准确定位。本文提出一种简单有效的 R 波检测方法,它不仅能够有效地抑制心率变异分析中的基线漂移、工频噪声、肌电、运动伪迹等干扰,提高实时检测 R 波准确率,并且能够对 R 波的峰值点准确定位。由于算法简单,适用于便携式心率变异分析仪。It is necessary to achieve reliable R wave detection performance and accu- rate peak point of R wave for the analyse of heart rate variability(HRV).In this paper we present a simple effective algorithm,which can not only effectively attenuate various noise components such as baseline wander,power—line interference,EMG and motion artefact in order to achieve improved real-time detection reliability,but also get accurate peak point of R wave.The algorithm can be used in the ambulatory device for HRV because of simpleness.
