Key result
Orthostatic tilt significantly increased heart rate and diastolic blood pressure, with changes in blood pressure variability being inversely related to resting heart period variability.
Why the study?
How does orthostatic tilt affect blood pressure variability in relation to resting cardiac autonomic control in healthy individuals?
Observational (n=22)
How does orthostatic tilt affect blood pressure variability in relation to resting cardiac autonomic control in healthy individuals?
Cardiac autonomic control appears to buffer blood pressure variability during sympathetic stress induced by orthostatic tilt.
No takes yet. Share an insight, caveat, or question.
Supports autonomic buffering of BP variability during orthostatic stress in healthy adults; leaves open extension to clinical populations.
Sloan et al. (1997) conducted an observational in Healthy (n=22). Orthostatic tilt was evaluated on Blood pressure variability (BPV) response. Orthostatic tilt significantly increased heart rate and diastolic blood pressure, with changes in blood pressure variability being inversely related to resting heart period variability.
