RRI Measurement Device, RRI Measurement Method and RRI Measurement Program - A simplified explanation of the abstract
This abstract first appeared for US patent application 18247818 titled 'RRI Measurement Device, RRI Measurement Method and RRI Measurement Program
Simplified Explanation
The abstract describes a measurement device for RRI (R-R interval) calculation in electrocardiogram signals. The device includes:
- R wave detection unit: Detects the peak point of an R wave in the electrocardiogram signal.
- Waveform estimation unit: Estimates the waveform near the R wave based on the detected peak point and surrounding data. It then re-detects the peak point of the R wave using the estimated waveform.
- RRI calculation unit: Calculates the RRI based on the time-series data of the detected R wave peak points.
Potential applications of this technology:
- Medical diagnosis: The device can be used in medical settings to analyze electrocardiogram signals and calculate RRI, which is useful for assessing heart rate variability and diagnosing various cardiac conditions.
- Wearable devices: The technology can be integrated into wearable devices such as fitness trackers or smartwatches to provide real-time monitoring of heart rate and RRI, enabling users to track their cardiovascular health.
Problems solved by this technology:
- Accurate R wave detection: The device improves the accuracy of R wave detection by estimating the waveform near the R wave and re-detecting the peak point. This helps in obtaining reliable RRI measurements.
- Efficient RRI calculation: By utilizing time-series data of R wave peak points, the device calculates RRI efficiently, providing a reliable measure of heart rate variability.
Benefits of this technology:
- Improved accuracy: The waveform estimation and re-detection process enhance the accuracy of R wave detection, leading to more precise RRI calculations.
- Real-time monitoring: The device enables real-time monitoring of RRI, allowing for timely detection of any abnormalities in heart rate variability.
- Non-invasive measurement: The technology utilizes electrocardiogram signals, which are non-invasive and widely available, making it convenient for users to measure RRI without the need for invasive procedures.
