[Ventricular extrasystole: prognostic value and therapeutic indication].

P Voiriot, E Aliot, J M Gilgenkrantz

    Annales De Cardiologie Et D'Angeiologie
    |February 1, 1984

    Summary

    Ventricular extrasystoles (VEBs) in healthy individuals generally pose no risk. However, in patients with heart disease, specific VEB patterns indicate a high risk of sudden cardiac death.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Internal Medicine

    Context:

    • Ventricular extrasystoles (VEBs) are common arrhythmias detected in both healthy individuals and cardiac patients.
    • Distinguishing the prognostic significance of VEBs is crucial for patient management.
    • Modern recording techniques facilitate frequent detection of VEBs.

    Purpose:

    • To analyze the prognostic implications of ventricular extrasystoles in various clinical settings.
    • To identify subgroups of patients with heart disease at high risk of sudden death due to VEBs.
    • To discuss the clinical relevance of VEB morphology versus clinical context.

    Summary:

    • In healthy subjects without coronary artery disease risk factors, VEBs have no adverse prognostic implication.
    • High-risk subgroups with underlying heart disease include ischemic cardiomyopathy, hypertrophic cardiomyopathy, symptomatic mitral valve prolapse, and long QT syndrome.
    • VEBs lack prognostic significance in idiopathic hypokinetic cardiomyopathies and aortic valvular disease.
    • The clinical context, rather than VEB morphology, primarily determines prognostic implications.
    • Treatment with anti-arrhythmics is recommended for high-risk groups, though treatment effectiveness requires further evaluation.

    Impact:

    • Provides a framework for stratifying sudden cardiac death risk based on VEBs in patients with heart disease.
    • Highlights the importance of clinical assessment over mere arrhythmia detection for prognosis.
    • Suggests the need for further research into ventricular stimulation therapies for high-risk patients.
