History of Heart Rate Variability

Abstract

The concept of heart rate variability is very old. Already early physicians observed variation in heart frequency, but only in the last 150 years more specific methods and ideas appeared. Rather than a comprehensive review, we offer here a sketch of the history of HRV. We mention names knowing that to relate a complex concept like HRV to single scientists is entirely wrong. In 1935, Ludwik Fleck was probably the first to describe scientific progress as collective work, arguing that to relate results to single scientists is not appropriate (Fleck 2012). We are convinced that his approach and interpretation could be easily used in the history of HRV. Thus, if we use specific names, this is not to highlight them at the expense of others who are similarly important. The authors are rather examples that stand for emerging concepts and discussions, while many more scientists and physicians also deserve credit. Therefore, we dedicate this chapter to the large historical community of clear-sighted and curious humans who have developed and are still developing the concept of heart rate variability in permanent collective interaction.
