  • Heart rate variability is the variability in heart rate from heartbeat to heartbeat. This can be calculated and specified by suitable mathematical methods, for example by a standard deviation, in particular the time interval between individual heart beats.
  • heart rate variability is the mathematical correlate to the permanent adaptation of the heart rate to changing requirements in the human organism and, in particular, is also an expression of the neurovegetative regulatory capacity of a human body.
  • the calculation of heart rate variability is performed on the one hand via a 24-hour ECG, which is recorded by means of a portable ECG recorder.
  • This procedure is usually used in cardiology issues and is relatively expensive. In particular, it also means a significant burden on the patient, since it must be connected to the portable ECG recorder for 24 hours. Targeted stimulation of heart rate variability does not occur in this procedure.
  • heart rate variability is determined as the result of various neurophysiological functional tests that specialize in it
  • Short term heart rate variability measurement at rest as testing procedures.
