“…Parents'/guardians' informed and written consents were obtained. The sample size was calculated using WHO sample size calculator considering the 34.5% frequency of arrhythmia , 11 95% confidence level at a 10% margin of error the minimum sample size was 100 patients. The approach of nonprobability sequential sampling was used.…”

Objective: To determine the frequency and clinical profile of arrhythmia and its immediate outcome in children presenting to a tertiary care center. Study Design: A cross-sectional study. Duration and place of study: July 2021 to June 2022, the National Institute of Cardiovascular Diseases, Karachi. Methodology: A total of 100 children of both gender , ranging in age from 1 day to 18 years, who presented with the symptoms of syncope, decreased or increased heart rate, chest discomfort, breathlessness were included in this study. Children who presented with cardiac arrhythmias had varying proportions of several criteria of relevance, such as clinical characteristics, age and gender distribution. In patients with unexplained arrhythmias or syncope, a thorough history, general physical exam, and cardiac examinations—including 12-lead electrocardiograms, 2-D echocardiograms, and Holter studies—were conducted. Results: A total of 100 children were included in this study among them 70 children presented with tachyarrhythmia and 30 children presented with bradycardia. The average age was 8.13± 4.45 years. Among the tachyarrythmias group the most frequent initial symptoms recorded in 45 (64.28%) and 15 (21.42%) youngsters, respectively, were palpitation and chest pain. A total of 19 (27.14%) children were discovered to have acyanotic CHDs. SVT was found to be the most common type of arrhythmia in 25 (30.1%) children, followed by ventricular tachycardia and atrial fibrillation in 15 (21.42%) and 10 (14.28%) of the same age groups. A total of 3 (4.28%) of the hospitalized children died. Among the bradycardia group 80% of children were found with complete heart block, 53.3% syncope, 26.7% were asymptomatic, and 20% were with multiple findings of irritability, poor feeding, breathlessness, and syncope. 20% of them developed LV dysfunction. Conclusion: The most frequent presenting symptoms were palpitations and chest discomfort. The other most common types of arrhythmia were supraventricular tachycardia, atrial fibrillation, ventricular tachycardia and bradycardia. Children's hospital stays were generally short and the therapy for arrhythmias had favorable overall results, however, 4.28% of children in the tachyarrhythmia’s group died of heart failure, while there was no expiry in the bradycardia group. Keywords: Arrhythmias, palpitations, supraventricular and ventricular tachycardia, bradycardia and heart Block

Objectives: The role of screening cardiac arrhythmias provides continuum of care to rediscover the causes and prevention strategies. This study was taken up to screen women working in the information and technology sector for cardiac rhythm disorders using continuous ambulatory cardiac monitoring and asses various risk factors along with work-related stress. Materials and Methods: A cross-sectional study was taken up at the workplace to screen women for cardiac rhythm disorders using wireless continuous ambulatory cardiac monitoring. Various risk factors and work-related stress were assessed using a standardized questionnaire. Differences in ECG parameters such as heart rate, heart rate variability (HRV), and frequency corrected QT (QTc) were compared on working and non-working days. Results: A total of 109 women were screened to find a proportion of 4.58% having cardiac arrhythmias. We found two cases of second-degree AV block (type 1), two cases of atrial tachycardia in the age group of 21–30 years, and one case of sinus pauses. Risk factors such as alcohol usage were statistically associated with cardiac arrhythmias. Others included a sedentary lifestyle, being underweight, a lesser number of sleep hours, no physical activity, work-related stress, and the presence of past-COVID-19 infection, but these were not statistically significant. There were significant changes in heart rate, HRV, and QTc prolongation on working day compared to non-working days. Among the domains of work-related stress, the influence at work and perceived stress due to individual demands and commitments contributed the highest mean score. Moreover, those with higher work-related stress scores were at 3.66 times the increased risk of QTc prolongation. Conclusion: The present study implies the combination of the need for the screening tool in younger age groups and lifestyle factors with more elucidation of work-related stress on autonomic cardiac function.
