The 5 Hz signal is well within the spectrum of the normal EKG (0-100 Hz), so a bandstop or other frequency-selective filter is inappropriate, as it will remove some of the EKG energy. The best option is to use a Savitzky-Golay filter (sgolayfilt) to eliminate most of the noise while keeping the essential parts of the EKG signal. .

The output ECG signal is the voltage difference between the two electrodes on the body with a total gain of 300, very low noise, and almost no DC offset. This output ECG signal will be used to amplitude-modulate the radio carrier frequency in Section 3-C. Figure 4. ECG Processing Circuit on Printed Circuit Board

the ECG signal from the body and the signal is amplified to 1 V level by the ECG preamplifier circuit. The output of the amplifier is directly connected with the Codec input of the DSK system. The Codec sampled the ECG signal at the sampled of 1 kHz. The data is stored in DSK buffer memory for processing. 3. Description Of the DSK Environment

The Sound Card ECG program provides a simple interface to view and measure ECG signals obtained through the sound card (using a line-in or microphone jack). The screenshot shows my heartbeat rate as I comfortably used the computer, then took a few minutes to watch a scary video (which elevated my heartrate for a few minutes in the middle). Download

ECG / EKG Signal Electrocardiography (ECG or EKG) is the study of the heart's electrical activity, most commonly recorded via placement of electrodes on the skin. Human and animal ECG signals can be recorded for easy processing of heart rate, heart rate variability, analysis of the waveform morphology, and similar functions.

ECG signals vary from the microvolt to the millivolt range. Due to this small range, the signals measured need to be amplified in order to be better interpreted. Typical biopotential amplifiers have high input impedance and are designed for safety first.
