Use of continuous holter of blood pressure in pediatric population: Single-center experience and review of literature

Introduction: A Holter blood pressure monitoring is a basic method for the diagnosis and evaluation of hypertension therapy. Hypertension in children and adolescents is defined as an increase of systolic/diastolic pressure, which is equal, or above 95th percentile blood pressure for sex, age, and height. Aim: The aim of this study is to analyze the etiology of arterial hypertension (AH) in the pediatric population. Methods: Research had descriptive and retrospective character. During the period from March 2006 to April 2020, 1527 registered continuous Holters of blood pressure were analyzed. Data were taken from the medical documentation of patients that were hospitalized on Pediatric Clinic (register of continuous Holter of blood pressure). Results: Out of the total number of registered and analyzed patients 833 were male (54.5%) with dominant age 15–19 years of life 774 (50.6%), school-age children 660 (43.2%), preschool children 93 (6.1%). We had 902 (59%) first registrations and 626 (41%) control registrations. AH was verified in 52 patients (387 records of continuous Holter of blood pressure were performed to them). Primary AH was verified in 27 patients and secondary AH in 25 patients. Forty patients (76.9%) were treated with monotherapy while combined therapy was used in 12 (23.1%) of cases. Renal cause was in 28% patients, endocrine in 24%, cardiovascular in 24%, neurological in 16%, and rheumatic in 8% of patients with secondary AH. Conclusion: Continuous Holter of blood pressure represents useful diagnostic method and method of control of high blood pressure in children and adolescents. It should be routine method in everyday pediatric clinical practice especially in pediatric cardiology.
