Establishing Standards of Orthostatic Measurements in Normovolemic Adolescents

Orthostatic Heart Rate and Blood Pressure in Adolescents: Reference Ranges

“…Horam and Roscelli found no significant difference in orthostatic heart rate changes in children aged 12 to 18 years with respect to age, ethnicity, gender, or body habitus. 6 We, too, did not find a significant difference in heart rate change with respect to ethnicity and body habitus, confirming the results of this earlier study. However, we did find a significant difference with respect to gender, with males having greater heart rate changes than females.…”

“…One study found a range of À3 to þ50 beats per minute and remarked that ''a healthy adolescent may have an orthostatic heart rate increase of 40 to 50 beats per minute.'' 6 Another study found an orthostatic heart rate change with active standing of 34 (+9) beats per minute. 18 The focused age group and large number of participants in our study are different from previous studies.…”

“…This was also found in other adolescent studies. 6,16 It appears that pronounced orthostatic heart rate changes and orthostatic symptoms are common in adolescents. In the population of adolescents we tested, 25% (76/307) would have met the adult diagnostic heart rate change criterion for postural orthostatic tachycardia syndrome with 31 of these adolescents also having acute orthostatic symptoms.…”

A cross-sectional study on upright heart rate and BP changing characteristics: basic data for establishing diagnosis of postural orthostatic tachycardia syndrome and orthostatic hypertension

“…Some studies showed that the change in heart rate from supine to upright position in children and adolescents was up to 40–50 bpm. 5 7 24 For instance, Skinner et al 5 showed that 307 adolescents aged between 15 and 17 years had a heart rate change from −1 to +48 bpm at 5 min standing. Furthermore, Yamaguchi et al 25 found that the development maturity influenced heart rate change from supine to upright position.…”

Emergency Nursing Resource: Orthostatic Vital Signs

“…In a contrasting population, different blood pressure changes were found in a convenience sample of 100 normovolemic adolescent patients, ages 12 to 19 years, in a study by Horam and Roscelli (1992). The mean SBP change ranged from a 17 mmHg decrease to a 19 mmHg increase, and diastolic blood pressure change ranged from a 7 mmHg decrease to a 24 mmHg increase.…”
