Electrocardiogram

5.1K
An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...

    Area of Science:

    • Biomedical Engineering
    • Medical Devices
    • Signal Processing

    Background:

    • Conventional electrocardiograph (ECG) measurements typically require direct skin contact using wet electrodes.
    • Existing methods can be uncomfortable and may not be suitable for continuous or long-term monitoring.
    • There is a need for non-invasive and convenient ECG monitoring solutions.

    Purpose of the Study:

    • To develop and validate a non-contact ECG measurement system using capacitive coupled electrodes.
    • To assess the system's performance in both contact and non-contact (through clothing) scenarios.
    • To evaluate the effectiveness of a real-time ECG denoising algorithm.

    Main Methods:

    • A non-contact ECG system was designed, incorporating capacitive coupled electrodes and a reference electrode.
    • A real-time ECG denoising algorithm based on wavelet transform with a moving window was implemented.
    • System performance was experimentally compared against traditional Ag/AgCl electrodes in contact and non-contact conditions.

    Main Results:

    • The capacitive coupled electrodes demonstrated superior performance compared to Ag/AgCl electrodes when in direct skin contact.
    • Clear ECG waveforms were successfully obtained even when measurements were taken through thin clothing.
    • The real-time denoising algorithm effectively improved signal quality.

    Conclusions:

    • The proposed non-contact ECG system using capacitive coupled electrodes is feasible for high-resolution measurements.
    • The system offers a promising non-invasive approach for ECG monitoring, even through clothing.
    • This technology has the potential to enhance patient comfort and monitoring accessibility.
