Microcontroller-Based Heart-Rate Meter

Prof. K. Padmanabhan

introduction

Heart rate can be measured either by the ECG waveform or by the blood flow into the finger (pulse method). The pulse method is simple and convenient. When blood flows during the systolic stroke of the heart into the body parts, the finger gets its blood via the radial artery on the arm. The blood flow into the finger can be sensed photoelectrically. To count the heart beats, here we use a small light source on one side ....etc

ABSTRACT
This paper presents a new measure of heart rate variability (HRV) that can be estimated using Doppler ultrasound techniques and is robust to variations in the angle of incidence of the ultrasound beam and the measurement noise. This measure employs the multiple signal characterization (MUSIC) algorithm which is a high-resolution method for estimating the frequencies of sinusoidal signals embedded in white noise from short-duration measurements. We show that the product of the square root of the estimated signal-to-noise ratio ....etc

ABSTRACT
HEART RATE DISPLAY USING 8051 MICROCONTROLLER
AIM:
The aim of this project is to implement an ECG and Digital Heart Rate counter. The main challenges include amplifying the desired weak signal in the presence of noise from other muscles and electrical sources. A display of the heart rate will be obtained by measuring the time between signal peaks and then calculating the frequency of the peaks in units of beats per minute.
PURPOSE:
The heart is one of the most vital organs within the human body. ....etc

Extraction Of Heart Rate Variability

Introduction

Heart Rate Variability (HRV)


HRV is the physiological phenomenon where the time interval between heart beats varies.

Dependant on the extrinsic regulation of the heart rate.

Useful for understanding the status of Autonomic Nervous System (ANS).

ABSTRACT
This project presents the optimal design of a health monitoring device worn during exercise--the
body heart rate monitor. The product provides the time and duration of exercise session, heart
rate of user, and calories burned during the session. The primary target market includes fitness
enthusiasts, professional and armature runners and cyclists, and heart patients.
The objective from an engineering viewpoint was to minimize overall size and weight, resulting
in an optimal size being 21 cm3 and weight being 143 g. The ....etc

Heart Rate Monitor
Abstract
The aim of this project is to implement an ECG and Digital Heart Rate counter. amplifying

the desired weak signal from the heart and isolating this from the noise signal from the

muscles were the main challenges. A display of the heart rate will also be implemented.The

time between signal peaks will be calculated and then the frequency of the peaks will be

obtained. Attempt is made to make the device portable. low cost amplifier and filter

components were used and it also includes ....etc
