Arrhythmia Alliance (A-A) works to improve the diagnosis, treatment and quality of life for all those affected by arrhythmias. A cardiac arrhythmia is the medical term for an irregular heartbeat or abnormal heart rhythm. Arrhythmias may occur at any age. Some are barely perceptible, whereas others can be more dramatic and can even lead to sudden cardiac death. A-A is a coalition of charities, patient groups, patients, carers, medical groups and allied professionals. Although these groups remain independent, they work together under the A-A umbrella to promote timely and effective diagnosis and treatment of arrhythmias. The Arrhythmia Alliance website contains information for both patients and clinicians about various related conditions and treatments, and has a range of downloadable information sheets and booklets.
