Abstract
The Pulse Rate Variability (PRV) is a very valuable quantitative method for studying the reactions of the two departments (sympathetic and parasympathetic)..
Highlights
The first HRV measurement was taken at rest 45 minutes after consuming 1 cup of instant coffee in the morning after sleep
The third measurement was performed after the second study. It includes measurement of Pulse Rate Variability (PRV) parameters at rest and a metronomic breathing test. All these data show the changes in PRV after consuming 1 cup of instant coffee and after 3 cups of instant coffee
From this one can get an idea of how instant coffee affects PRV [1-8]
Summary
Measurement of the Parameters of Pulse Rate Variability (Resting Test, Orthostatic Test, Metronomic Breathing Test) After Intake of 1 and 3 Cups of Instant The Pulse Rate Variability (PRV) is a very valuable quantitative method for studying the reactions of the two departments (sympathetic and parasympathetic) of the autonomic nervous system to various factors and substances.
