Can you exercise with atrial fibrillation?
For many people, the answer is yes.
Regular exercise can be an important part of managing cardiovascular health with AF, and research suggests it can help improve exercise capacity, symptoms and quality of life.
What can be different is how we interpret the exercise response.
Because AF produces an irregular rhythm, heart rate may fluctuate more than expected and may not always provide the clearest picture of exercise intensity on its own.
That is why things like how hard the exercise feels, workload, breathing, symptoms and recovery can all provide useful additional information.
Some people with AF have very few symptoms. Others may notice palpitations, breathlessness, fatigue or reduced exercise tolerance — and the experience can vary from day to day.
At Heartworks, the aim is not simply to chase a particular heart-rate number. It is to understand the overall response and help find an exercise level that is appropriate for the individual.
If you are new to exercise or returning after a change in your AF, start gradually and discuss your exercise plan with your healthcare team.
AF may change the rhythm — but it doesn’t necessarily mean movement has to stop. ❤️
