and coronary heart disease due to population ageing and
stressful modern life. If proper medical care can be given to
the patients at the right time their lives can be saved, for that
we need is a system that continuously monitors ones ECG
signal, so this system is develop. This system can be used by
patient for self-diagnosis, and remote-diagnosis for chronic
heart disease patients before sudden outbreaks. This system
will continuously monitor the ECG signal the body and if
any deviation is found will generate an alert. This system is
mainly useful for patient living alone and has disability. The
System will measure the ECG (EKG) signal using three lead
electrocardiography and transmit these signals to Smartphone
via Bluetooth for processing and generating proper alert. -It is

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.)
