    Area of Science:

    • Biomedical Engineering
    • Cardiology
    • Signal Processing

    Context:

    • Modern cardiologic monitoring units often suffer from reduced data reliability during patient motion.
    • Motion artifacts are a significant challenge in acquiring accurate electrocardiogram (ECG) data.

    Purpose:

    • To enhance the noise immunity of cardiologic monitoring units.
    • To introduce and evaluate an R-wave selector circuit for improved signal discrimination.

    Summary:

    • The study proposes an R-wave selector that improves noise immunity by analyzing signal rate and pulse decay duration (RS-slope).
    • Two circuit designs, parallel and series, were considered, with the series version noted for easier implementation.
    • Optimal threshold values for the R-wave selector were determined to be 12 ms for rate and 14 ms for duration.

    Impact:

    • This R-wave selector technology can significantly improve the diagnostic accuracy of cardiologic units in real-world, dynamic patient conditions.
    • The findings offer practical solutions for developing more robust and reliable cardiac monitoring devices.
