    A runaway pacemaker caused syncope by firing rapidly, leading to ventricular arrhythmia. This case highlights a rare, fast-firing ventricular parasystolic focus.

    Area of Science:

    • Cardiology
    • Biomedical Engineering

    Background:

    • Pacemakers are crucial for managing bradycardia.
    • Device malfunction can lead to life-threatening arrhythmias.

    Observation:

    • A patient experienced syncope due to a pacemaker firing at 30 impulses per second.
    • The ventricular arrhythmia included ectopic beats and ventricular tachycardia.

    Findings:

    • The arrhythmia exhibited coupling intervals dependent on preceding cycle length.
    • Characterized as a very rapidly firing, low-intensity, ventricular parasystolic focus.

    Implications:

    • This case underscores the importance of monitoring pacemaker function.
    • Understanding parasystolic foci is vital for managing complex arrhythmias.
