Insights
Cardiac event recorders are useful for diagnosing pediatric arrhythmia symptoms like palpitations and syncope. This study found a 39% symptom-rhythm correlation, supporting their use as a primary diagnostic tool in children.
Area of Science:
- Pediatric Cardiology
- Cardiac Electrophysiology
- Diagnostic Tools
Background:
- Cardiac event recorders are increasingly utilized in pediatric care.
- Assessing the efficacy of these recorders in diagnosing pediatric cardiac conditions is crucial.
Purpose of the Study:
- To evaluate the experience and diagnostic utility of cardiac event recorders in pediatric patients.
- To determine the symptom-rhythm correlation in children experiencing potential arrhythmia-related symptoms.
Main Methods:
- A cohort of 460 pediatric patients (mean age 12.8 years) fitted with cardiac event recorders for 15-30 days was analyzed.
- Patients underwent electrocardiograms, Holter monitoring, and echocardiography prior to event recording.
- Exclusion criteria included no recorded events or artifact-contaminated records.
Main Results:
- Palpitations were the most common indication (73%), followed by chest pain and palpitations (21%), and syncope (6%).
- Sinus tachycardia (25%) and supraventricular tachycardia (8%) were the most frequent recorded events.
- A symptom-rhythm correlation of 39% was observed, leading to electrophysiology study/ablation in 46 patients.
Conclusions:
- Cardiac event recorders serve as a valuable primary diagnostic method for children with possible arrhythmia-related symptoms.
- Further research is warranted to fully elucidate the role of event recorders in pediatric cardiac diagnostics.
Background:
In this study, we reported our experience with the use of cardiac event recorders in pediatric patients.
Methods:
We evaluated 583 patients fitted with an event recorder (15-30 days) between March 2010 and November 2014 at our clinic. Excluded from the study were 117 patients with no recorded events and six with records contaminated by electrocardiogram artifacts. All of the patients received electrocardiograms, Holter monitoring, and echocardiography before the cardiac event recording.
Results:
The patient sample consisted of 460 patients (64% female). The mean age was 12.8 ± 4.1 years. The median number of recorded events was 7. The indications included palpitations in 336 (73%) patients, syncope in 27 (6%) patients, and chest pain and palpitations in 97 (21%) patients. Whereas 64 patients (14%) had structural heart disease according to echocardiographic examination, the remaining patients had normal echocardiographic examination results. The most frequent cardiac comorbidities were mitral valve prolapse (6%), operated tetralogy of Fallot (1.5%), and complicated congenital heart diseases with single ventricle physiology (1%). The recorded events were sinus tachycardia in 113 (25%) patients, supraventricular tachycardia in 35 (8%) patients, ventricular extrasystole in 20 (4%) patients, supraventricular extrasystole in nine (2%) patients, and ventricular tachycardia in two (0.4%) patients. Based on the event recorder and follow-up electrocardiogram findings, 46 patients received an electrophysiology study/ablation. The symptom-rhythm correlation was 39%.
Conclusion:
In the presence of possible arrhythmia-related symptoms in children, a cardiac event recorder can be considered a useful primary diagnostic method. More research on this topic is needed.
