[High frequency component of heart rhythm]

S A Dudin, V V Boronoev

    Biofizika
    |November 1, 1996
    PubMed
    Summary

    Autocorrelation analysis revealed a distinct heart rhythm with a period of two cardiointervals. This finding suggests a connection to a lower-level cardiac governing system.

    Area of Science:

    • Cardiology
    • Physiology
    • Biomedical Engineering

    Context:

    • The study analyzes the heart rhythmogram derived from electrocardiogram (ECG) R-R peaks and sphygmograms.
    • Investigates the high-frequency component of the heart rhythmogram using autocorrelation analysis.

    Purpose:

    • To identify and characterize rhythmic patterns within the heart rhythmogram.
    • To explore the significance of rhythms with a period of two cardiointervals.

    Summary:

    • Autocorrelation analysis of the high-frequency component of the heart rhythmogram identified a rhythm with a period of two cardiointervals (approximately 27 beats).
    • This rhythm manifested as a negative correlation coefficient at the first shift on the autocorrelation function curve.
    • Wave dispersion calculations indicated that rhythms with a 2T period possess significant power, comparable to higher-order rhythms (10-20s and 30-50s).

    Impact:

    • The identified rhythm with a two-cardiointerval period is likely associated with a lower-level cardiac governing system.
    • This research contributes to understanding the complex regulatory mechanisms of heart rate variability.
    • Findings may inform diagnostic tools for cardiac autonomic function assessment.
