US EditionMiddle-Aged Folks At Risk For Irregular Heartbeat, Especially If They Don't Work Out
The study involving 1,151 healthy adults aged 40-65 found that irregular heartbeat risk increases 9% annually with age and low aerobic fitness, urging early screening after age 50.
- On August 27, 2025, researchers presented at the 2025 European Society of Cardiology Congress, Madrid, linking older age and low aerobic fitness to arrhythmia burden in 1,151 healthy adults aged 40–65.
- Age-Stratified analysis showed arrhythmia prevalence rose markedly from age groups 50–54, with atrial risk increasing 9% and ventricular risk 4% annually; older age linked to ventricular arrhythmias.
- Frequency and type analysis found about 32% had supraventricular tachycardia, 4% atrial fibrillation, and 6% non‑sustained ventricular tachycardia; adults 40–65 with low fitness faced 52% higher arrhythmia risk.
- The researchers urged age-based rhythm checks from around age 50, emphasizing that exercise like walking, running, and cycling should suit individual capacity, as Dr Amit Moses said.
- The team cautioned that as an observational study in a not-very-diverse population, findings remain preliminary until peer-reviewed journal publication, and future research must test interventions for arrhythmia risk.

Older age and low fitness identified as independent risk factors for heart rhythm disorders
New research has revealed that older age and low aerobic fitness levels are strong and independent risk factors for a high burden of heartbeat irregularities, known as arrhythmias, that indicate future cardiovascular risk.

Older age and low fitness levels associated with heartbeat abnormalities that increase future cardiovascular risk
New research has revealed that older age and low aerobic fitness levels are strong and independent risk factors for a high burden of heartbeat irregularities, known as arrhythmias, that indicate future cardiovascular risk. The research was conducted in healthy participants between the ages of 40 and 60 years old with no heart symptoms.
