    Summary

    Multiple ventricular parasystole, a rare arrhythmia, involves multiple ectopic foci discharging independently. This study describes two cases, highlighting diagnostic challenges and potential mechanisms, suggesting it may be more common than previously thought.

    Area of Science:

    • Cardiology
    • Electrophysiology
    • Cardiac Arrhythmias

    Background:

    • Ventricular parasystole is an uncommon arrhythmia characterized by an ectopic pacemaker that discharges independently of the sinus node.
    • Multifocal ventricular parasystole, involving multiple independent ventricular pacemakers, is exceptionally rare and poorly understood.
