|June 1, 1979
Summary
This study introduces a novel preprocessor for electrocardiogram analysis, achieving high accuracy in measuring R-wave intervals. This innovation enables the detection of subtle heart rate variations, improving diagnostic capabilities for cardiac conditions.
Area of Science:
- Biomedical Engineering
- Cardiology
- Signal Processing
Background:
- Accurate measurement of the time interval between successive R waves (R-R interval) is crucial for diagnosing cardiac arrhythmias.
- Existing methods may lack the precision required to detect subtle beat-to-beat variations in heart rate.
Purpose of the Study:
- To develop and describe a preprocessor for precise R-R interval determination in electrocardiogram (ECG) signals.
- To enable the detection of abnormal heart rate patterns with minimal beat-to-beat variability.
Main Methods:
- Hardware-based separation of R-wave detection and peak localization functions.
- High-precision R-wave peak identification with an error of less than 0.2 ms.
Main Results:
- The developed preprocessor accurately determines R-R intervals with sub-millisecond precision.
- The device successfully identifies abnormal heart rate patterns characterized by very small beat-to-beat variability.
Conclusions:
- The novel preprocessor offers a significant advancement in ECG analysis accuracy.
- This technology has the potential for improved diagnosis of cardiac conditions and may be applicable to other bioelectric signals.
