See what is next in human behavior research. Renal diseases (such as chronic kidney insufficiency). View source a measurement of the variation in time between each heartbeat. The Poincar plot therefore shows how well each RR interval predicts the next a greater spread of values would mean an increased HRV, while the closer they bunch together, the less HRV there is. Measurements of high-frequency (HF; 0.15 Hz to 0.4 Hz) and very-low-frequency (VLF) are also used. When we have several heartbeats next to each other, then the distance (in milliseconds) between each R is defined as the RR interval (or sometimes the NN interval to emphasize that the heartbeats are normal). Researchers have found that an increase in HRV is related to increased self-control abilities, greater social skills, and better abilities to cope with stress, among other findings.
