1. Faster walking pace associated with reduced risk of cardiac arrhythmias, including atrial fibrillation.
2. Time spent walking at a brisk pace linked to lower risk of arrhythmias.
3. Metabolic and inflammatory markers partly accounted for the association between slow walking pace and arrhythmia risk.
4. Associations stronger in specific demographic groups, such as women, individuals younger than 60 years, those with a BMI below 30, and participants with at least two long-term conditions.
5. Limitations include reliance on self-reported pace, potential selection bias, and healthy volunteer bias.
