Abstract

Research conducted by the World Health Organisation (WHO) in 2018 demonstrated that the worldwide threat of cardiovascular diseases (CVDs) has increased compared to previous years. CVDs are very dangerous: if timely treatment is not performed, these conditions could become irreversible and lead to sudden death. Prescriptive measures include physical exercises and monitoring of the heart rate (HR). Despite the existence of various HR monitoring devices (or HMDs), a major challenge remains their availability, particularly to people in lower-income countries. Unfortunately, it is also this segment of the population that is the most vulnerable to CVDs. Accordingly, this led the authors to propose the design for an easily constructible state-of-the-art HMD that attempts to provide a highly accessible, lower-cost, and long-lasting solution that would be more affordable and accessible to these low-income communities.

Highlights

An investigation conducted around the world by the WHO demonstrated that cardiovascularrelated disease has become the number one killer worldwide (World Health Organisation (WHO), 2017)
The results indicated that the difference in wavelength affects the Component Ratio (CR) and that the CR affects the correlation coefficients of the heart rate and pulse rate, especially at skin temperatures above 38°C
Taking advantage of the PPG technology, the present work essentially seeks to contribute to the improvement of the world health condition by proposing a state-of-art working prototype heart rate (HR) monitoring device

Summary

INTRODUCTION

An investigation conducted around the world by the WHO demonstrated that cardiovascularrelated disease has become the number one killer worldwide (World Health Organisation (WHO), 2017). Detection of CVDs is an advantage because some of them can be treated Left untreated, they can lead to serious adverse health problems including hypertension, atrial fibrillation, and stroke. This is one further reason which motivated the invention of the Photoplethysmography (PPG) based HR monitoring. PPG technology is a non-invasive optical technique that measures blood volume changes (Allen, 2007) In this concept, light is shone at the tissue and the backscattered light is measured by a photodetector. In PPG, the photodetector collects the light that is absorbed in tissue and the resulting signal represents the absorption changes due to the variations in blood volume (Allen, 2007). The main intention is to contribute to the improvement of world health by enabling lower-income revenues and third world countries to be able to take control of their HR monitoring at cheaper costs with the reproduction of the current proposal
