Key result
Computerized autonomic testing correlates strongly with manual methods for measuring heart rate responses.
Why the study?
A standardized, objective, and faster computerized method for measuring heart rate and heart rate response to autonomic function tests was needed to replace the traditional manual method.
Does a computerized data analysis system provide comparable results to the traditional manual method for evaluating cardiovascular autonomic responses in healthy subjects and diabetic patients?
Population
97 healthy subjects and 143 patients with diabetes mellitus
Comparison

Does a computerized data analysis system provide comparable results to the traditional manual method for evaluating cardiovascular autonomic responses in healthy subjects and diabetic patients?
A computerized method for calculating autonomic function test responses is comparable to the traditional manual method, offering advantages of speed and objectivity.
Neumann et al. (1997) conducted an observational in Diabetes mellitus and healthy subjects (n=240). Computerized data analysis system vs. Traditional manual method was evaluated on Heart rate and heart rate response to Valsalva maneuver, standing, and deep breathing. A computerized data analysis system strongly correlated with manual methods; age correlated with heart rate response to standing (r=-0.48, P<0.001) and deep breathing (r=-0.41, P<0.002).
