A.I. Health Assistant Causes for Racing Heart Beat

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced racing heart beat. This list does not constitute medical advice.

  1. 1.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.

    Uncommon
    Top Symptoms:
    fatigue, anxiety, rib pain, shortness of breath, racing heart beat
    Urgency:
    Primary care doctor
  2. 2.Panic Disorder

  3. 3.Premature Ventricular Contractions

    Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a feeling of a skipped beat in your chest.

    This condition is considered irreversible, but it often does not require treatment and will not prevent you from living a healthy life.

    Rarity:
    Uncommon
    Top Symptoms:
    racing heart beat, deep chest pain, behind the breast bone, racing heart beats that lasts for seconds, irregular heart beat, racing heart beat that lasts for minutes

  4. 4.Vitamin B12 Deficiency

    Vitamin B12 is a vitamin crucial to healthy neurological and cardiovascular functioning. If deficient, symptoms include trouble thinking, anxiety, stomach issues, and weakness.

    Symptoms resolve completely when B12 levels return to normal.

    Rarity:
    Common
    Top Symptoms:
    fatigue, depressed mood, difficulty concentrating, history of headaches, racing heart beat
    Symptoms that never occur with vitamin b12 deficiency:

  5. 5.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:
    fatigue, chest pain, shortness of breath, racing heart beat, lightheadedness
    Urgency:

  6. 6.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
  7. 7.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

    Folic acid (folate) is a vitamin that is needed to make new cells in the body, including red blood cells which carry oxygen through the blood and into various tissues throughout the body. Folate deficiency refers to a condition when there is not enough folic acid in the body, and can lead to symptoms such as tiredness, low energy, faintness, and difficulty breathing.

    People recover with no long-term effects within weeks.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, depressed mood, irritability, nausea or vomiting, diarrhea
