7 Potential Racing Heart Beat Causes

Disclaimer: The article does not replace an evaluation by a physician. Information on this page is provided as an information resource only, and is not to be used or relied on for any diagnostic or treatment purposes.

  1. 1.Panic Disorder

    Panic disorder is a type of anxiety disorder. It causes panic attacks, which are sudden feelings of terror without true danger. One may feel as if they are losing control or have physical symptoms like sweating or a racing heart.

    Chronic with relapses

    Rarity:
    Common
    Top Symptoms:
    anxiety, abdominal pain (stomach ache), nausea, stomach bloating, depressed mood
    Symptoms that always occur with panic disorder:
    anxiety
    Symptoms that never occur with panic disorder:
    agoraphobia
    Urgency:
    Primary care doctor
  2. 2.Aortic Valve Regurgitation

    Aortic valve regurgitation is a condition that occurs when your heart's aortic valve doesn't close tightly. This allows some of the blood that was just pumped out of the lower left chamber (left ventricle) to leak back into it.

    Can be severely acute or chronic.

    Rarity:
    Common
    Top Symptoms:
    shortness of breath, racing heart beat, shortness of breath on exertion, shortness of breath when lying down, brief fainting episode
    Urgency:
    Primary care doctor
  3. 3.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:
    Common
    Top Symptoms:
    fatigue, shortness of breath, chest pain, racing heart beat, shortness of breath on exertion
    Urgency:
    Emergency medical service

  4. 4.Coxsackie b Virus Infection

    Coxsackie B Virus usually doesn't cause any symptoms but can be the cause of nonspecific fever and, in rare cases, lung or heart infections. The disease is most common in children but adults are susceptible too.

    3-4 days

    Rarity:
    Uncommon
    Top Symptoms:
    fever, fatigue, headache, nausea, loss of appetite
    Symptoms that always occur with coxsackie b virus infection:
    fever
    Urgency:
    Self-treatment
  5. 5.Atrial Flutter

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

    If the flutter only occurs once and there is no underlying heart disease, it is likely to never happen again.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, lightheadedness, deep chest pain, behind the breast bone, shortness of breath on exertion
    Urgency:
    In-person visit
  6. 6.Mitral Valve Prolapse

    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.

    Rarity:
    Uncommon
    Top Symptoms:
    fatigue, anxiety, rib pain, shortness of breath, racing heart beat
    Urgency:
    Primary care doctor
  7. 7.Hypertrophic Cardiomyopathy

    Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). 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.

    Hypertrophic cardiomyopathy is a life-long condition, as the heart walls are permanently enlarged.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, dizziness, racing heart beat, shortness of breath on exertion
    Urgency:
    Primary care doctor
