“…Overall, the system can track the HR during treadmill exercise. The system also shows good results for the IMET on a cycle ergometer [29]. Compared to traditional FFT methods, the proposed algorithm shows significant improvements in the removal of motion artifacts from cardiac physiologic spectra.…”

Photoplethysmography (PPG) is a non-invasive optical technique that can be used to quantify the arterial blood pulse rate. Signal corruption by motion artifacts limits the practical accuracy and applicability of instruments for monitoring pulse rate during intense physical exercise. This study develops and validates an algorithm, which is based on linear filtering and frequency-domain and heuristic analyses, for extracting the heart rate from a PPG signal in the presence of severe motion artifacts. The basis of the hearth beat frequency selection is the observed high harmonic content of movement artifact signals with respect to the PPG-derived heartbeat. The algorithm, implemented in an experimental PPG measurement device, is developed by analyzing a set of PPG data recorded from a group of athletes exercising on a treadmill. An extensive set of tests is carried out during maximal exercise tests on a treadmill to validate the proposed algorithm by comparison with a reference electrocardiography measurement system. The Bland-Altman method is used to compare and evaluate PPG signals. The accuracy of the heartbeat measurement is better than ± 6.5 beats per minute (bpm) ( ≤ 4.2 %) even under maximal exercise conditions.

“…Researchers have designed numerous devices to effectively measure the electrical activity of the heart both invasively and non-invasively. [1,2] Conventional ECG monitors use complex wired structures called leads which are used to pick up the electrical impulses from different positions of the body, It follows the Einthoven triangle and consists of twelve leads for the proper monitoring. [3,4,5] It is not at all cost efficient and requires trained experts for its proper operation.…”

In the field of medical electronics, non invasive techniques for the measurement of different physical and physiological parameters are becoming popular nowadays. The use of different types of sensors is inevitable to design this type of instruments. The present study deals with such a design based on the concepts of Pulse oxymetry. It is an infra red sensor based wireless module which measures pulse rate, maximum heart rate, blood pressure, physical fitness index and maximum oxygen uptake capacity of an individual noninvasively. It provides a graphical representation of the electrical activity of the heart commonly known as Electrocardiograph (ECG) which helps to detect any existing disorders in the cardiac cycle. In this study, the sensor-receiver module is touched with the subject's finger. The output of the receiver is fed to a series of sensitively tuned electronic amplifier circuit which represents the electrical activities of the heart in the form of voltage fluctuations. Then the voltage fluctuation is passed through appropriate filters for precision. The change in the voltage is due to the fluctuation of voltage within the heart muscles (commonly myocardium) which are amplified and displayed in a display unit. The whole measurement is performed by keeping a single finger of the patient between the sensor-receiver modules for twenty seconds. Each change in blood volume has a fixed curve pattern and depicts one cardiac cycle. The total number of change in blood volume in a minute gives the pulse rate of the patient. Several attempts have been made by researchers to measure the electrical activity of the human heart non-invasively, but it was not possible from a single finger, if preceded in the conventional way. This instrument is a portable device and removes the drawbacks of conventional 44 Sayan Dey et alElectrocardiograph machines. It is very much cost effective and is fully sensor based digital device providing complete computer interfacing. This is a low power device, designed to provide full cardiac monitoring and is meant to help the medical experts to diagnose any cardiac disorders very easily and within very less time.
