  1. 1.Atrial Fibrillation

    An arrhythmia is a problem with the speed or rhythm of the heartbeat. The atria comprise two out of the four chambers of the heart. When their beat is disturbed, symptoms such as a racing heart, chest pain, breathlessness, and dizziness may occur.

    More than 1/2 of people with short term atrial fibrillation get their normal heart rhythm back in less than 2 days without any treatment.
