    Electrical cardioversion (ECV) is effective for restoring sinus rhythm in atrial fibrillation and atrial flutter.

  • 2

    Serum potassium levels influence myocardial excitability and electrical conduction, impacting arrhythmia occurrence.

  • 3

    The study evaluated low-normal versus high-normal potassium levels' effect on immediate ECV success in atrial fibrillation.

  • 4

    A total of 647 patients were analyzed, with 48.5% having low-normal potassium and 51.5% having high-normal potassium.

  • 5

    No significant difference in ECV success rates was observed between patients with low-normal and high-normal potassium levels.
