Key result
Active standing in healthy children transiently lowers BP and increases HR by ~40 bpm.
Why the study?
The magnitude and time course of circulatory adaptation to active standing in healthy premenarchic children aged 10–14 years were not well characterized.
How does active standing affect heart rate and blood pressure in healthy 10-14-year-old children?
Observational (n=24)
No
How does active standing affect heart rate and blood pressure in healthy 10-14-year-old children?
Healthy children aged 10-14 frequently exhibit orthostatic tachycardia and presyncopal symptoms during active standing, with no significant differences in circulatory adaptation between sexes.
No takes yet. Share an insight, caveat, or question.
Similar orthostatic responses by sex in premenarchic children; leaves open pubertal influences on adult syncope differences.
Dambrink et al. (1991) conducted an observational in Healthy (n=24). Active standing vs. Passive head-up tilt / supine was evaluated on Changes in blood pressure and heart rate upon standing. Active standing in healthy 10-14-year-old children caused an initial transient drop in blood pressure and a heart rate increase of 40 ± 7 beats/min, with no important differences between sexes.
