Electrocardiograms in school-aged healthy Polish children - an observational study.

Background: Electrocardiographic (ECG) examination has long been used to assess cardiovascular function in clinical practice. Age-related ECG changes are observed as the cardiovascular system matures from the neonatal period to adolescence.

Aim: This study aimed to evaluate effects of sex and age on ECG parameters in healthy schoolchildren.

Normative Values for Heart Rate Variability Parameters in School-Aged Children: Simple Approach Considering Differences in Average Heart Rate.

Heart rate variability (HRV) analysis is a clinical tool frequently used to characterize cardiac autonomic status. The aim of this study was to establish normative values for short-term HRV parameters by considering their main determinants in school-aged children. Five-minute electrocardiograms were taken from 312 non-athlete children (153 boys) at age of 6 to 13 years for computation of conventional time- and frequency-domain HRV parameters.

Bland-White-Garland syndrome - a rare and serious cause of failure to thrive.

Patient: Male, 0 FINAL DIAGNOSIS: Bland-White-Garland syndrome Symptoms: Cardiomegaly, feeding problems Medication: - Clinical Procedure: Reimplantation of the left coronary artery to the aorta Specialty: Pediatrics and Neonatology.

Objective: Rare disease.

Background: Bland-White-Garland syndrome (BWGS) is a very rare disease characterized by anomalous origin of the left coronary artery from the pulmonary trunk (ALCAPA).

[Parainfluenza type 3 virus infection in neonates with cardiac arrhythmia].

The aim of the study was to assess the frequency of the occurrence of parainfluenza type 3 virus infection in neonates with cardiac arrhythmia. In 12 (17%) out of 70 of neonates parainfluenza type 3 virus infection was recognized basing on serologic hemagglutinin inhibition test. Ten of them were diagnosed with mild course of myocarditis.
