Background: Changes in QT interval is one of the important electrocardiographic parameters which are reported in many clinical conditions not only in adults but also among the pediatric age group. Diseases with a high risk of sudden deaths in the pediatric age group have initiated the interests among the researchers to focus on electrocardiographic studies. Aims and Objectives: This pilot study was done to obtain the normal QT values for the various age groups and both the genders of pediatric subjects. Materials and Methods: A cross-sectional study was conducted which included 162 healthy children (93 males and 69 females) and electrocardiographic recordings were taken. Subjects with congenital or acquired cardiovascular diseases were excluded from the study. Results: All the participants were divided into three age groups of 1-5 years, 6-10 years, and 11-15 years. It was found that heart rate was inversely proportional to QT/QTc interval while RR interval was directly proportional to both QT and QTc interval. With age, heart rate decreases but other electrocardiograms parameters increase progressively. Although the heart rate is inversely correlated with QT/QTc interval, there is positive correlation of QT/QTc with RR interval. Conclusion: Electrocardiography should be started as a routine investigation in pediatric subjects for the diagnosis of congenital and acquired cardiac diseases and arrhythmias which can be evident from QT interval determination.
Introduction: Acute under-five wheezers are the most suitable group for targeting focus aimed at reducing unnecessary use of antibiotics. Viral bronchiolitis is an important cause of wheezing in under-five children. Rationality behind antibiotic usage has rarely been reported from Odisha. Aim: The aim of the present study is to look into the decision of private practitioners of Bhubaneswar, Odisha, for an antibiotic prescription to under-five wheezers. Materials and Methods: Hundred prescriptions of private practitioners for under-five patients suffering from acute wheeze were analyzed between January and June 2016. The prescriptions were grouped as with antibiotics (Group A) and without antibiotics (Group B). The groups were compared for the presence of clinical, hematological, and radiological signs and results were statistically analyzed. Result: The number of prescriptions with antibiotic inclusion is higher (67%). Antibiotics are mostly prescribed to younger patients. Antibiotic administration was significantly higher with the symptoms of fever, tachypnea, crepitation’s and leukocytosis, and X-ray findings. (p<0.05) The average recovery period was almost the same in both the groups. The prescription patterns in the present study show rational usage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
