Why the study?
Does spectral analysis provide comparable baroreflex sensitivity measurements to the phenylephrine test in patients with chronic heart failure?
Population
49 patients with chronic congestive heart failure
Comparison
Spectral analysis of systolic arterial pressure… vs Phenylephrine test (invasive method)

Spectral analysis should not substitute for phenylephrine testing in heart failure; leaves open optimal baroreflex sensitivity standardization for research.
Does spectral analysis provide comparable baroreflex sensitivity measurements to the phenylephrine test in patients with chronic heart failure?
Spectral analysis and the phenylephrine test show poor agreement for assessing baroreflex sensitivity in heart failure patients and cannot be used interchangeably.
COLOMBO et al. (1999) studied this question.
