Area of Science:
- Biomedical Engineering
- Cardiology
- Medical Device Design
Background:
- Continuous electrocardiogram (ECG) monitoring is crucial for diagnosing cardiac arrhythmias.
- Existing Holter monitors can be expensive and less portable.
- There is a need for cost-effective and accessible ECG monitoring solutions.
Purpose of the Study:
- To design and describe a low-cost, portable Holter monitor.
- To utilize off-the-shelf components for ease of implementation and reduced cost.
- To provide a functional device for extended continuous ECG data acquisition.
Main Methods:
- Development of a portable ECG recorder using commercially available components.
- Integration of a battery power source, graphical display, and keyboard interface.
- Implementation of data acquisition capabilities for continuous ECG recording.
Main Results:
- A functional low-cost portable Holter recorder was successfully designed.
- The device is battery-powered and features a user-friendly interface with a graphical display and keyboard.
- The recorder can acquire up to 48 hours of continuous ECG data at a sample rate of up to 250 Hz.
Conclusions:
- The described Holter monitor design offers a viable, low-cost alternative for portable ECG monitoring.
- The use of off-the-shelf components facilitates accessibility and potential widespread adoption.
- This portable ECG device supports extended monitoring periods, aiding in cardiac diagnostics.
