Premature ventricular beats in a previously healthy child
Insights
A 12-year-old experienced chest pain and irregular pulse due to frequent premature ventricular contractions. Diagnostic tests confirmed the cardiac dysrhythmia was benign, resolving without medication.
Area of Science:
- Pediatric Cardiology
- Cardiac Electrophysiology
Background:
- Chest pain is a common presenting complaint in pediatric emergency departments.
- Premature ventricular contractions (PVCs) can occur in children and warrant thorough investigation.
Observation:
- A 12-year-old female presented with left-sided chest pain and an irregular pulse.
- Electrocardiogram (ECG) showed 30-50 premature ventricular contractions per minute with bigeminy.
- Antiarrhythmic medication failed to resolve the PVCs during intensive care unit admission.
Findings:
- Comprehensive diagnostic workup included echocardiogram, Holter monitoring, and exercise stress testing.
- The cardiac dysrhythmia was characterized as unifocal premature ventricular contractions with a specific ECG pattern.
- The unifocal premature ventricular contractions were determined to be benign in nature.
Implications:
- Benign premature ventricular contractions in children do not necessitate antiarrhythmic therapy.
- This case highlights the importance of a detailed diagnostic approach to pediatric arrhythmias.
- Accurate diagnosis prevents unnecessary medical interventions and associated risks.
Abstract:
A 12-year-old girl presented to the emergency department with a chief complaint of left-sided chest pain. On physical examination she was noted to have an irregular pulse, and an electrocardiogram revealed 30 to 50 premature ventricular contractions per minute with periods of bigeminy. The patient was admitted to the intensive care unit and treated with antiarrhythmic medication without resolution of her premature ventricular contractions. A diagnostic workup, including echocardiogram, Holter monitoring, and exercise stress testing, was performed. It was determined that the cardiac dysrhythmia, consisting of unifocal premature ventricular contractions with a characteristic configuration on the electrocardiogram, was benign in nature and did not require antiarrhythmic therapy.
