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.
