Key result
An active standing test established diagnostic thresholds for POTS (ΔHR ≥38 bpm or max HR ≥130/125 bpm) and OHT (ΔSBP ≥20 mm Hg or ΔDBP ≥25/20 mm Hg) in children and adolescents.
Why the study?
What are the normative upright heart rate and blood pressure changes during an active standing test in Chinese children and adolescents?
Cross-Sectional (n=1,449)
Yes
What are the normative upright heart rate and blood pressure changes during an active standing test in Chinese children and adolescents?
The study provides normative data for heart rate and blood pressure changes during active standing in Chinese children, proposing specific diagnostic thresholds for POTS and orthostatic hypertension.

May inform pediatric POTS/OHT thresholds in Chinese youth; leaves open prospective validation before clinical use.
Zhao et al. (2015) conducted a cross-sectional in Postural orthostatic tachycardia syndrome (POTS) and orthostatic hypertension (OHT) (n=1,449). Active standing test was evaluated on Upright heart rate and blood pressure (BP) changes. An active standing test established diagnostic thresholds for POTS (ΔHR ≥38 bpm or max HR ≥130/125 bpm) and OHT (ΔSBP ≥20 mm Hg or ΔDBP ≥25/20 mm Hg) in children and adolescents.
