Top 10 Feeling Completely Normal Before Fainting Causes

  1. 1.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.

    You should visit your primary care physician within the next 24 hours if you are feeling fatigue, weakness, shortness of breath, chest pain, irregular pulse or sensations of a rapid, fluttering heartbeat. Depending on severity, you may or may not need treatment.

    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
  2. 2.Atrial Flutter

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

    You should visit your primary care physician within the next 24 hours. Your doctor will examine your heartbeat with an ECG (electrocardiogram) to confirm the diagnosis. Prescription medication is available to return the heart rhythm back to normal.

    Rarity:
    Common
    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
  3. 3.Long Qt Syndrome

    Long QT syndrome (LQTS) is a disorder of the heart's electrical activity. It can cause sudden, uncontrollable, dangerous arrhythmias in response to exercise or stress. Arrhythmias are problems with the rate or rhythm of the heartbeat.

    You should visit your primary care physician, who will do an ECG to measure the electrical rhythym of your heart, which may identify the diagnosis. Treatment involves stopping meds that could've caused it or a defibrillator.

    Rarity:
    Common
    Top Symptoms:
    racing heart beat, brief fainting episode, not having protected the body during the fall, feeling completely normal before fainting
    Urgency:
    Primary care doctor
  4. 4.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.

    You should visit your primary care physician. Cardiomyopathy is usually treated with prescription medication to slow down the heart rate and make the heart squeeze less forcefully. In severe cases of cardiomyopathy, an operation called myectomy is performed to remove a segment of thickened muscle from the wall dividing the right and left ventricle (the septum).

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, dizziness, racing heart beat, shortness of breath on exertion
    Urgency:
    Primary care doctor
  5. 5.Congenital Long Qt Syndrome

    Congenital Long QT syndrome is a disorder of the heart's electrical activity from birth, causing possibly dangerous rhythm changes.

    You should visit a physician today, who will perform an ECG to look at your heart's rhythms.

    Rarity:
    Rare
    Top Symptoms:
    racing heart beat, brief fainting episode, not having protected the body during the fall, feeling completely normal before fainting
    Urgency:
    In-person visit

  6. 6.Supraventricular Tachycardia

    Supraventricular tachycardia (SVT) is a form of arrhythmia that causes the heart to beat too quickly and begins in the heart's upper chambers. The most common symptoms include a racing heart, lightheadedness and palpitations.

    You should visit a physician today to get an EKG to confirm this diagnosis.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, racing heart beat, lightheadedness, deep chest pain, behind the breast bone
    Symptoms that always occur with supraventricular tachycardia:
    abnormally high heartrate
    Urgency:
    In-person visit
  7. 7.Third Degree Atrioventricular Nodal Block

    3rd degree atrioventricular nodal block is the most severe form of conduction blockage.

    You should visit your primary care physician within the next 24 hours, where an ECG can measure your heart's electrical impulses, which would reveal the diagnosis. Treatment would involve treating reversible causes, medications for acute worsening, and/or cardiac pacing.

    Rarity:
    Rare
    Top Symptoms:
    racing heart beat, shortness of breath, lightheadedness, deep chest pain, behind the breast bone, tight, heavy, squeezing chest pain
    Symptoms that never occur with third degree atrioventricular nodal block:
    swelling of one leg, swelling of one foot, swollen ankle
    Urgency:
    Primary care doctor
  8. 8.Stress - Induced Cardiomyopathy

    In this recently recognized heart problem, extreme emotional stress can lead to severe (but often short-term) heart muscle failure. Broken heart syndrome is also called stress-induced cardiomyopathy.

    You should visit your primary care physician within the next 24 hours. Your doctor will likely prescribe heart medications to reduce the workload on the heart while you recover.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, deep chest pain, behind the breast bone, excessive sweating, muscle aches
    Urgency:
    Primary care doctor
  9. 9.Eisenmenger Syndrome (Tardive Cyanosis)

    Eisenmenger syndrome is a complication due to a heart defect. The defect causes increased blood flow to the lungs instead of the body.

    You should visit your primary care physician, who can prescribe medications that improve your quality of life. Surgery is usually not recommended when the syndrome has developed.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, shortness of breath on exertion, shortness of breath when lying down, lightheadedness
    Urgency:
    Primary care doctor
  10. 10.Ebstein Anomaly of the Tricuspid Valve

    Many heart conditions are present from birth (congenital), and some can cause the valves to function improperly, resulting in symptoms such as poor blood circulation, fatigue, and difficulty breathing.

    You should visit your primary care physician. You may need to be treated by a heart specialist (cardiologist). It is likely that your physician will want to perform imaging or tests to determine if surgery is appropriate.

    Rarity:
    Rare
    Top Symptoms:
    shortness of breath, racing heart beat, severe fatigue, lightheadedness, deep chest pain, behind the breast bone
    Urgency:
    Primary care doctor
