Insights
Pediatric ventricular extrasystole, common in children with healthy hearts, typically shows a good prognosis. Many cases are asymptomatic, with a high rate of spontaneous improvement over time.
Area of Science:
- Pediatric Cardiology
- Electrophysiology
- Rhythm Disorders
Background:
- Ventricular extrasystole is a frequent arrhythmia in children.
- Most pediatric cases occur in structurally normal hearts.
- Understanding the clinical course is crucial for management.
Purpose of the Study:
- To evaluate the clinical course of ventricular extrasystole in children without cardiac structural abnormalities.
- To assess the long-term outcomes and natural history of this condition.
Main Methods:
- Retrospective analysis of 24-hour Holter recordings.
- Inclusion criteria: isolated ventricular extrasystole and absence of structural heart disease on echocardiography.
- Follow-up duration averaged 8.7 years.
Main Results:
- 226 children met the criteria; 81.8% were asymptomatic.
- Palpitations were the most common symptom; syncope occurred in 5 patients.
- 42% showed partial reduction, 22% complete recovery; no cardiomyopathy developed.
Conclusions:
- Pediatric ventricular extrasystole generally has a favorable prognosis.
- High rates of spontaneous regression are observed.
- The condition is typically benign in children with normal cardiac structure.
Objective:
Ventricular extrasystole is one of the most common rhythm disorders in children, and almost all of them are characterized by normal cardiac functions without structural cardiac abnormalities. The aim of this study was to assess the clinical course of ventricular extrasystole in children who did not have cardiac structural abnormalities.
Materials And Methods:
This retrospective study analyzed 24-hour rhythm Holter recordings performed in our clinic in children. Patients diagnosed with isolated ventricular extrasystole in Holter records and without structural heart disease on echocardiography were included in the evaluation.
Results:
A total of 20 160 Holter results were evaluated in the study, and 226 patients (male; 66%) met the criteria. The mean follow-up time was 8.7 ± 3.2 years. While 81.8% of the patients were asymptomatic, the most common symptom was palpitation and 5 patients had syncope. Of the patients, 72 (31.8%) received medical therapy. Beta-blockers were the most often pre- scribed medication. Cardiomyopathy did not develop in any of the patients during the follow- up period. A partial reduction in the frequency of ventricular extrasystole was observed in 42% of the patients, while complete recovery was observed in 22%.
Conclusion:
Ventricular extrasystole in children generally has a good prognosis; most of them are asymptomatic, and the rates of spontaneous regression over time are quite high, regard- less of the origin.
