%A Dr Valery Mukhin %T AMPLITUDE OF HEART RATE MODULATION WITH THE PERIOD OF 3 CARDIOCYCLES DEPENDS ON THE PHYSIOLOGICAL AROUSAL OF THE BRAIN %X Amplitude of the 3-cardiocycle modulation of heart rate in records of 300 cardiointervals depends of the physiological arousal of brain. As arousal is a physiological component of stress, the amplitude of this heart rate modulation may be used as a diagnostic parameter on the arousal in stress related studies. %D 2009 %K heart rate variability, mental status, arousal of the brain, meditation, sleeping %P 36-37 %L cogprints6838
