Development of Low Cost Heart Rate Monitoring Device and Classification Technique Using Fuzzy Logics Algorithm

Heart as one of necessary organs, has been examined profoundly by the heart rate
changes. The heart rate is affected by many factors, such as age, gender, physiological
conditions. Hence, better diagnosis can be made if the interpretation of heart rate signal
would be automated that eliminates the human error while comprising the influential
factors. Subjective readings may lead to imprecise diagnosis. In this project, proposed tool
is designed for medical experts that can reliably interpret the heart signal based on age,
gender and heart condition. PPG sensor was utilized to sense the heartbeats. Furthermore,
the raw signal was transferred through wireless medium using RF Transceivers and
Arduino Uno as a microcontroller to the remote base station. This would let end users
(physicians/Caregivers) to have a real-time heart rate monitoring without a need of
connecting wires from the patient ward/room to the remote station which was designed in
MATLAB GUI. The classification of the signal being obtained is achieved through fuzzy
logics algorithm inside the MATLAB Fuzzy Logic Toolbox. The cost-effectiveness of the
proposed project was another benefits that could be added to an automated heart rate
monitoring device.
