Mayer waves
Mayer waves
Mayer waves (pronunciation: /ˈmaɪər weɪvz/), also known as Traube-Hering-Mayer oscillations, are spontaneous oscillations in arterial blood pressure occurring at a frequency of approximately 0.1 Hz (6 cycles per minute). These waves are named after the German physician Julius Friedrich Cesar Mayer, who first described them in 1876.
Etymology
The term "Mayer waves" is derived from the name of Julius Friedrich Cesar Mayer, a German physician who first described these oscillations in arterial blood pressure. The term "Traube-Hering-Mayer oscillations" also includes the names of two other physicians, Ludwig Traube and Karl Ewald Konstantin Hering, who made significant contributions to the understanding of these waves.
Description
Mayer waves are characterized by rhythmic oscillations in arterial blood pressure, typically occurring at a frequency of approximately 0.1 Hz. These oscillations are believed to be a result of fluctuations in the activity of the sympathetic nervous system, which regulates blood pressure. Mayer waves are often observed in conditions of increased sympathetic activity, such as during physical stress or disease states.
