Heart Rate Variability - Heart Rate Variability Phenomena

Heart Rate Variability Phenomena

There are two primary fluctuations:

  • Respiratory arrhythmia (or Respiratory sinus arrhythmia). This heart rate variation is associated with respiration and faithfully tracks the respiratory rate across a range of frequencies.
  • Low-frequency oscillations. This heart rate variation is associated with Mayer waves (Traube–Hering–Mayer waves) of blood pressure and is usually at a frequency of 0.1 Hz or a 10-second period.

Famous quotes containing the words heart, rate, variability and/or phenomena:

    A man is relieved and gay when he has put his heart into his work and done his best; but what he has said or done otherwise shall give him no peace.
    Ralph Waldo Emerson (1803–1882)

    You are more than entitled not to know what the word ‘performative’ means. It is a new word and an ugly word, and perhaps it does not mean anything very much. But at any rate there is one thing in its favor, it is not a profound word.
    —J.L. (John Langshaw)

    The grand points in human nature are the same to-day they were a thousand years ago. The only variability in them is in expression, not in feature.
    Herman Melville (1819–1891)

    War seems to be one of the most salutary phenomena for the culture of human nature; and it is not without regret that I see it disappearing more and more from the scene.
    Karl Wilhelm Von Humboldt (1767–1835)
