Monitor stroke volume and heart rate

Microcontroller Based Heart Rate Monitor

This paper describes the development of a heart rate monitor system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The paper explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by email every twenty four hours. I...

Heart Rate Monitor and Electrocardiograph Fundamentals

This application note demonstrates fundamental implementations of the cost effective heart hate monitor (HRM) and electrocardiograph (ECG or EKG) devices using Freescale products. The heart rate monitor is implemented on a low cost MC9RS08KA2 ultra low-end 8-bit microcontroller using an analog comparator module (ACMP) and standard IO pins. The electrocardiograph is implemented on the MC9S08JM60...

Intelligent Pillow for Heart Rate Monitor

The aim of the project is to develop intelligent pillow to monitor the heart rate by using fiber optical sensor. The research is focused upon allowing more automation of patient care, an especially important matter for the elder population or bedridden patients, which is a rapidly growing fraction of much of the world population today. The fiber-optical sensor is built into pillow. Patients can...

Heart rate and increased intravascular volume.

The objective was to establish whether an intravascular volume increase leads to a heart rate (HR) increase without increased sympathetic tonus. HR changes at rest and at deep breathing (6/min - simulated increase of atrial filling pressure) were measured in patients after heart transplantation. Evaluation of dependency of HR changes on breathing depth was done through a new time series methodo...
