Ventricular arrhythmias: a perspective on management.

B K Valladares, L Lemberg

    Heart & Lung : the Journal of Critical Care
    |July 1, 1985
    PubMed
    Summary

    Antiarrhythmic drugs can cause dangerous heart rhythm problems and other side effects. Treatment decisions for ventricular arrhythmias should consider arrhythmia type, frequency, and heart disease to prevent sudden cardiac death.

    Area of Science:

    • Cardiology
    • Pharmacology

    Background:

    • Antiarrhythmic drugs are frequently prescribed for cardiac rhythm disorders.
    • These medications carry a risk of significant adverse effects, including proarrhythmia.

    Observation:

    • Ventricular arrhythmias require careful management due to potential for sudden cardiac death.
    • The decision to initiate antiarrhythmic therapy necessitates a thorough evaluation of the arrhythmia and patient's cardiac status.

    Findings:

    • Antiarrhythmic drug therapy is linked to a notable rate of arrhythmogenic effects.
    • Other cardiac and extracardiac side effects are also associated with these drugs.

    Implications:

    • Clinical decisions regarding antiarrhythmic drug use must be individualized.
    • Factors such as arrhythmia frequency, qualitative characteristics, and underlying heart disease are critical in risk stratification.
    • Personalized treatment strategies are essential to mitigate the risk of sudden arrhythmogenic death.
