A Microcontroller Based Heart Rate Monitoring and Conditions Detection System

Cardio Vascular Disease is one of the leading causes of deaths in Nigeria with a staggering number of about 150,000 deaths annually as compiled by the Nigerian Heart Foundation (NHF). A good number of these deaths are a result of wrong observation and late detection of the disease. This system provides a means of reducing the number of deaths caused by cardiovascular diseases through the design and implementation of a portable and cost-effective device for the detection and monitoring of heart rate conditions. System performance testing was carried out by measuring the pulse rate and detecting the state of the heart at 5-minute intervals for 50 minutes. The produced results of the system show an average error of 2.8% in comparison to the data measured by the application of Cardiac diagnosis and an error of 2.2% in comparison to the traditional means of measuring heart rate. Hence the designed system can be used effectively to monitor and detect cardiovascular diseases.
