Unfortunately, their ‘slope parameters’ do not correspond to the graph’s actual slope which complicates the analysis and bears the risk of misreporting. Variants of the 4-parameter Boltzmann sigmoidal equation are widely used for curve fitting. After fitting the parameters of a sigmoidal function to the data, the graph’s characteristics represent a rather comprehensive quantitative reflex description. In an X-Y plot the data points scatter around a sigmoidal curve. These data pairs relate intervals between heartbeats or sympathetic neural activity to blood pressure values. 4Division of Clinical Pharmacology, Department of Medicine, Autonomic Dysfunction Center, Vanderbilt University Medical Center, Nashville, TN, United StatesĪrterial baroreflex assessment using vasoactive substances enables investigators to collect data pairs over a wide range of blood pressures and reflex reactions.3University of Cologne, Cologne, Germany. ![]()
