What are the tests and treatments for atrial flutter?
Your doctor might recommend that you have an ECG or echocardiogram test or an electrophysiological (EP) study to help diagnose atrial flutter.
Once your atrial flutter has been confirmed, your doctor might recommend a cardioversion or ablation treatment, and /or medicines such as beta-blockers, calcium channel blockers and other anti-arrhythmic medicines.
To reduce this risk of having a stroke, you may also need to take an anticoagulant medicine such as warfarin.
