  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.

    Rarity:
    Rare
    Top Symptoms:

  3. 3.Atrial Flutter

    Atrial fibrillation or flutter is a common type of abnormal heartbeat. The heart rhythm is fast and irregular in this condition.

    Mitral valve prolapse (MVP) occurs when the valve between the heart's left upper chamber (left atrium) and the left lower chamber (left ventricle) doesn't close properly because the flaps of the valve are "floppy." Most people who have the condition are born with it.

    Without surgery, this is a lifelong condition.

This happens sometimes as a result of long-term elevated blood pressure, and sometimes without any particular reason. The thickened heart muscle can make it harder for the heart to pump blood.
