Premature ventricular contractions in normal children.

J R Jacobsen, A Garson, P C Gillette

    The Journal of Pediatrics
    |January 1, 1978
    PubMed
    Summary

    Premature ventricular contractions (PVCs) in children without heart disease generally have a benign prognosis. Most children with PVCs remained asymptomatic and their condition resolved with light exercise.

    Area of Science:

    • Pediatric Cardiology
    • Electrophysiology
    • Clinical Outcomes

    Background:

    • Premature ventricular contractions (PVCs) are common in children.
    • The long-term prognosis of pediatric PVCs without structural heart disease is not well-established.
    • Previous studies suggest a benign course, but long-term follow-up data are limited.

    Purpose of the Study:

    • To evaluate the long-term prognosis of premature ventricular contractions (PVCs) in children.
    • To determine if PVCs in children without other cardiac conditions are benign.
    • To identify clinical factors associated with the prognosis of pediatric PVCs.

    Main Methods:

    • A cohort of 17 children with PVCs and no other heart disease was followed for a mean of 7 years.
    • Data collection included medical history, physical examination, 15-lead electrocardiogram (ECG), and treadmill exercise testing.
    • Clinical data and ECG findings were analyzed at baseline and during follow-up.

    Main Results:

    • Eight of the 17 children (47%) continued to have PVCs at the most recent follow-up.
    • Seven of these eight children remained asymptomatic.
    • PVCs were unifocal in all patients and disappeared with light exercise in all cases. One child developed mitral valve prolapse.
    • Physical examinations remained normal in all but one child.

    Conclusions:

    • Unifocal premature ventricular contractions (PVCs) in children without underlying heart disease appear to have a benign prognosis.
    • A normal clinical examination, unifocal PVCs, and resolution with exercise suggest no further cardiovascular evaluation is needed.
    • These findings support the assumption of a benign course for pediatric PVCs under specific clinical conditions.
