Pulse and heart rate variability
The pulse describes the pressure wave that spreads in the blood vessels as a result of the contraction of the heart. Rest pulse is understood to be the frequency of the heartbeat when the body is at rest. For the correct measurement of the resting heart rate, it is necessary that the measurement does not take place immediately after physical exertion and that the subject has come to rest before the measurement.
Heart rate variability (HRV) is a spontaneous variation of the heart rate (heartbeat) and describes the ability of the heart to adapt to different performance situations.
A healthy heart doesn't beat steadily like a clock. There are time differences in the range of milliseconds between two contractions of the heart chamber, which are shown in the ECG as so-called R-waves. The difference in distance between two R waves reflects the size of the HRV.
Heart rate variability is the physiological phenomenon of the variation in the time interval between successive heartbeats in milliseconds. If we look at the time in milliseconds between heartbeats, there is usually a constant fluctuation. You can get a picture of your HRV by feeling your pulse and taking a few deep breaths: as you breathe out, the intervals between beats get longer and the pulse slows down, and when you breathe in, your pulse gets faster.
A lack of magnesium, for example, can lead to a racing heart. In turn, cinnamon can help lower blood pressure. If you are stressed or nervous, your heart rate can also increase.
It shows the number of times the heart contracts without stress / per minute to pump blood around the body. The resting heart rate is also known as the normal pulse or normal resting pulse.
The resting heart rate is the number of heartbeats in the resting state. That is when the body is not under any strain. In general, the resting heart rate is understood to be the resting heart rate.
