Cardiovascular autonomic function tests in an African population

BMC Endocrine Disorders

Table 3 Cut-off values for cardiovascular autonomic tests based on ≥ 95th or ≥ 5th percentile.

Variable	Category	Resting HR (bpm)	HR in response to deep breathing (bpm)	HR in response to standing (bpm)	Fall in postural SBP (mmHg)	Fall in postural DBP (mmHg)
Age groups (years)	20–29		≤ 13	≤ 14	≥ 17^b
	30–39		≤ 11	≤ 11^a
	40–49		≤ 9
	50–59		≤ 8
	60+		≤ 7
Gender	Men	≥ 89				≥ 2
	Women	≥ 97				≥ 5

The 95th percentile cut-off value applies to resting HR and postural changes in SBP and DBP.
The 5th percentile applies to HR variation in response to deep breathing and to standing.
^aThis cut-off value applies to age groups of 30+ years.
^bThis cut-off value applies to all age groups.
