Description: Electrocardiogram (ECG) is used in order to discover
the heart disease early. Especially, R-R interval gives
an useful information for the heart condition. The purpose
of this study is the detection of an accurate R
wave position zn order to extract the R-R interval of
the ECG. Recently, a method for detecting the position
of an R wave was proposed using moving averaged
magnitude difference(MAMD). Since there is individual
difference in the ECG waveform, however, improvement
of the approach is necessary. We proposed the
R/S wave enhancement filter(RSEF) in preprocessing
and an R wave detection algorithm which adaptively
decides search region. The algorithm searches for only
the short time duration estimated from the most recent
R-wave position in order to detect the next R-wave eficiently.
We call this duration a Window. In this paper,
the comparison between the MAMD and the RSEF is
also znvestigated. Platform: |

Description: 心电图(ECG)是临床上诊断心血管疾病的重要方法。
数字滤波作为数字信号处理技术的重要组成部分，广泛应用于诸如信号分离、恢复、整形等多种场合中。为了使信号不失真及在可编程逻辑器件中容易实现，采用具有严格线性相位特性的FIR滤波器进行低通滤波（0-150Hz），用整系数梳状滤波器来去工频干扰及基线漂移,从而达到对心电信号进行预处理的目的。(Electrocardiogram (ECG) is an important method for clinical diagnosis of cardiovascular diseases.
As an important part of digital signal processing technology, digital filtering is widely applied to many occasions, such as signal separation, recovery, shaping and so on. In order to make the signal undistorted and easy to be realized in programmable logic device, the FIR filter with strict linear phase characteristics is used for low pass filtering (0-150Hz), and the entire coefficient comb filter is used to get the interference of the power frequency and the baseline drift, thus the purpose of preprocessing the ECG signal is achieved.)
