Parent Terms Term With Siblings Child Terms
absolute change in electrocardiographic low frequency R-R spectral component to high frequency R-R spectral component ratio  
absolute change in heart rate  
change in heart rate to change in intracerebroventricular sodium concentration ratio 
change in heart rate to change in mean arterial blood pressure ratio +  
change in heart rate to change in vasoactive chemical dose ratio 
This is a calculated measurement in which the difference in the heart rate recorded between two or more dosages of a drug or chemical which reduces or increases the interior diameter of blood vessels is divided by the difference of the applied dosages and presented as a ratio, fraction, quotient or percentage. The value is calculated as the slope of the curve of the heart rate versus the chemical dose graph.
heart rate variability  
percent change in heart rate 
range of heart rate variation during variation of mean arterial blood pressure +  
rate-pressure product 

Synonyms
Exact Synonyms: beta coefficent of the heart rate/ vasoactive chemical dose curve ;   index of baroreceptor sensitivity ;   slope of the heart rate/ vasoactive chemical dose curve
