Terminating ventricular fibrillation by chest thump.

J L Bierfeld, V Rodriguez-Viera, J M Aranda

    Angiology
    |October 1, 1979
    PubMed
    Summary

    A chest thump successfully converted ventricular fibrillation to sinus rhythm in a patient with a history of atrial septal defect. This is the first reported case of mechanical conversion for ventricular fibrillation.

    Area of Science:

    • Cardiology
    • Cardiac Electrophysiology
    • Medical Case Reports

    Background:

    • A 41-year-old male with a surgically repaired atrial septal defect experienced prolonged anginal symptoms.
    • The patient underwent coronary angiography for diagnostic evaluation.

    Observation:

    • During coronary angiography, the patient developed ventricular fibrillation.
    • A precordial thump was administered, successfully converting the ventricular fibrillation to sinus rhythm.

    Findings:

    • This case represents the first documented instance of successful mechanical conversion of ventricular fibrillation using a chest thump.
    • The mechanism may involve interruption of re-entrant pathways or suppression of ectopic impulses by the mechanical stimulus.

    Implications:

    • Chest thump may be a viable, immediate intervention for certain life-threatening arrhythmias.
    • Further research is warranted to elucidate the precise mechanisms and clinical utility of mechanical cardioversion.
