Healthcare is most often unaffordable to the average salary earner. Due to this, individuals do not see the required yearly medical examination as a priority. These check-ups would keep people informed of developments in their health as they age and help prevent some avoidable health conditions, especially cardiovascular diseases. With this knowledge, there is a need for an accessible and affordable way for people to regularly check their heart function and make informed decisions that can help evade critical circumstances. The medical sector in Africa still has a great deal to provide optimum health care to individuals. Many factors, such as long wait times, non-affordable medical insurance and misdiagnosis, keep people further away from visiting hospitals until an emergency arises. In this project, a low-cost heart monitoring system using an electrocardiogram (ECG) is designed. Individuals or community clinics can check the heartbeat/rhythm of patients with possible heart problems while saving time and cost spent at hospitals. The device was designed with an analog circuit for amplification and filtering the signal and post-processing on MATLAB. During testing, the signal was gotten and routed through the microphone jack of a PC to MATLAB for digital filtering. The system will be further developed to include sound indicators for the visually impaired.
