[The problem of ventricular flutter and fibrillation]

D Weber, D Wittig, B Uhlmann

    Zeitschrift Fur Die Gesamte Innere Medizin Und Ihre Grenzgebiete
    |March 15, 1981
    PubMed
    Summary

    Ventricular flutter and fibrillation are life-threatening heart rhythm disturbances. Immediate electro-shock therapy is crucial for survival, with some patients recovering successfully.

    Area of Science:

    • Cardiology
    • Electrophysiology

    Context:

    • Ventricular flutter and fibrillation cause ineffective heart contractions, leading to circulatory collapse.
    • These malignant arrhythmias are often fatal if untreated, stemming from reentry or rapid impulse formation.

    Purpose:

    • To discuss the electrophysiological mechanisms, etiologies, and therapeutic outcomes of ventricular flutter and fibrillation.
    • To analyze the significance of warning arrhythmias and intraventricular conduction disturbances.

    Summary:

    • Electrophysiological mechanisms include reentry or rapid impulse formation; warning arrhythmias are significant but not always predictive.
    • Etiologies encompass myocardial infarction, myocarditis, ischemic heart disease, and cardiomyopathies.
    • Paroxysmal ventricular fibrillation, often linked to prolonged QTU-time, requires immediate electro-shock therapy for survival.

    Impact:

    • Immediate electro-shock therapy offers the only chance of success for ventricular flutter and fibrillation.
    • Out of 61 patients studied, 26 were successfully treated and discharged, highlighting the importance of prompt intervention.
