    The study involved 106 male endurance athletes aged 50 and older, tracking their exercise patterns and monitoring for ventricular arrhythmia.

  • 2

    Ventricular arrhythmia occurred in 23.5% of athletes, with 94.5% of events classified as non-sustained ventricular tachycardia (NSVT).

  • 3

    Myocardial fibrosis was significantly more prevalent in athletes with ventricular arrhythmia compared to those without (76% vs. 38.3%).

  • 4

    Acute exercise exposure was linked to a higher risk of ventricular arrhythmia, while chronic exercise load showed no significant association.

  • 5

    The findings suggest that myocardial fibrosis may be a critical factor in triggering arrhythmias during intense exercise in older male athletes.
