Possible triggers
- alcohol, especially binge drinking
- large amounts of caffeine or energy drinks
- lack of sleep, stress and illness
- smoking
Keeping a diary of when symptoms happen can help you spot patterns.
Exercise
Regular, moderate exercise is good for your heart and can reduce AF. Ask your doctor what level is right for you.
Taking blood thinners safely
- take them at the same time every day
- carry an anticoagulant alert card
- check with a pharmacist before taking other medicines, herbal remedies or supplements
Driving
You do not usually need to tell the DVLA about AF if you drive a car, unless it causes symptoms such as dizziness or fainting that could affect your driving. Different rules apply to lorry and bus drivers.
Travel
Take enough medicine and a list of your medicines. On long journeys, move around and drink water.
Support
The AF Association and the British Heart Foundation have helplines and information.
