Overview

• Findings were presented at ESC Congress 2025 in Madrid by a Chaim Sheba Medical Center team led by Dr. Amit Moses.
• Arrhythmia odds rose about 9% per year for atrial events and 4% for ventricular events, with a marked uptick starting at ages 50–54.
• Lower aerobic fitness independently predicted higher atrial ectopy and complex atrial arrhythmias, while age also related to ventricular ectopy.
• Continuous monitoring identified complex rhythms in the cohort: 32% supraventricular tachycardia, 4% atrial fibrillation, and 6% nonsustained ventricular tachycardia.
• The authors proposed considering age-based screening from about 50 and underscored the observational design and male-heavy sample as key limitations requiring further study.
