Mayer waves are waves in arterial blood pressure brought about by oscillations in baroreceptor and chemoreceptor reflex control systems.[1][2] 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."[3]
