Heart Rhythm Disorders

Heart Rhythm Disorders, or cardiac arrhythmias, are caused by the heart beating irregularly. This can cause symptoms of palpitations (a sense that the heart is beating abnormally and uncomfortably), breathlessness, occasionally chest pains, dizziness and even blackouts, although some patients may not be aware of having an arrhythmia. Most forms of heart rhythm disorder are now well understood and effective treatments can be offered for both benign and serious disorders. The different classifications and treatments for arrhythmias are covered by leading heart specialists in this section.
