Spectral analysis of blood pressure and heart rate

Parameter	MSA	PAF	Healthy controls	P value
LF SBP, mmHg²	1.9 (0.8 to 4.7)	1.1 (0.6 to 2.7)	5.8 (3.3 to 7.9)	0.010^*
BRS, ms/mmHg	5.5 (2.5 to 9.6)	3.3 (1.7 to 8.3)	7.2 (4.9 to 9.4)	0.098
LF _RRI, ms²	42.9 (20.7 to 143.5)	19.1 (3.2 to 77.3)	320.1 (201.4 to 352.5)	<0.001^**
HF _RRI, ms²	15.9 (6.8 to 32.4)	11.8 (4.9 to 28.2)	102.6 (64.5 to 310.3)	0.008^**

Values represent median (interquartile range, IQR). RRI, R-R interval; SBP, systolic blood pressure; DBP, diastolic blood pressure; BRS, baroreflex slope; LF, low frequency; HF, high frequency.
