Feasibility of P wave Centric Ambulatory Electrocardiogram Monitoring in Infants and Young Children

P wave centric ambulatory electrocardiographic (ECG) monitoring has emerged as an important tool aiding the diagnosis of arrhythmias. However, their efficacy and user experience in infants young children are not well established. A retrospective study was performed to detail clinical ECG using Carnation Ambulatory Monitor (CAM) patch (Bardy Diagnostics Inc., Seattle, WA) patients less than 10 kg. Additionally, 2 different monitor locations (over sternum horizontal over left axilla) were assessed address optimal placement these patients. total 33 CAM reports from 25 patients, aged 0 to15 months included study. Mean patient age 4.2 ± 5.0 mean weight 5.3 kg 2.4. Thirty-six percent (9/25) had known congenital heart disease. Indications for included: tachyarrhythmia (15/33, 45%), bradyarrhythmia (6/33, 18%), ectopic rhythm (9/33, 27%), cardiac tumor (1/33, 1%), prolonged QT interval 1%). All showed clear, identifiable waves which diagnostic lead changes medical management 30% (e.g., medication adjustments or discharge cardiology care). We found upright better axilla small single-lead is helpful providing accurate diagnostics tracings management.
