Mayer waves
Encyclopedia
Mayer waves are waves in arterial
blood pressure
brought about by oscillations in baroreceptor
and chemoreceptor reflex control systems. The waves are seen both in the ECG and in blood pressure
curves and have a frequency about 0.1 Hz (10-second waves). These waves were originally described by Siegmund Mayer
, Ewald Hering and Ludwig Traube
hence originally called "Traube–Hering–Mayer waves".
Mayer waves are correlated with heart rate variability
.
Takalo et al. (1999) state that "the frequency shift of Mayer waves to lower frequencies is associated with an increased risk of developing established hypertension

Artery
Arteries are blood vessels that carry blood away from the heart. This blood is normally oxygenated, exceptions made for the pulmonary and umbilical arteries....

Blood pressure
Blood pressure is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, "blood pressure" usually refers to the arterial pressure of the systemic circulation. During each heartbeat, BP varies...

Baroreceptor
Baroreceptors are sensors located in the blood vessels of several mammals. They are a type of mechanoreceptor that detects the pressure of blood flowing through them, and can send messages to the central nervous system to increase or decrease total peripheral resistance and cardiac output...

Heart rate variability
Heart rate variability is a physiological phenomenon where the time interval between heart beats varies. It is measured by the variation in the beat-to-beat interval....

Hypertension
Hypertension or high blood pressure is a cardiac chronic medical condition in which the systemic arterial blood pressure is elevated. What that means is that the heart is having to work harder than it should to pump the blood around the body. Blood pressure involves two measurements, systolic and...
