Top 10 Heart Rate Precursor Causes

  1. 1.Ventricular Tachycardia

    Ventricular tachycardia (VT) is a rapid heartbeat that starts in the ventricles. Ventricular tachycardia is a pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row.

    Call 911 immediately for an ambulance now! This is a medical emergency that could be life-threatening!

    Rarity:
    Rare
    Top Symptoms:
    racing heart beat, chest pain, shortness of breath, lightheadedness, irregular heart beat
    Symptoms that always occur with ventricular tachycardia:
    racing heart beat
    Urgency:
    Emergency medical service
  2. 2.Graves' Disease

    The thyroid gland is a butterfly-shaped organ inside the neck that is responsible for making thyroid hormones. These hormones control important body functions, such as heart rate and the rate at which the body turns food into energy. In Grave's disease, the immune system malfunctions and drives the thyroid to produce excessive amounts of hormones, leading to symptoms such as trouble sleeping, irritability and nervousness, heat sensitivity, hand tremors, and weight loss.

    You should visit your primary care physician to get your blood tested. Grave's disease is a complex condition that is managed with prescription antithyroid medications, as well as surgery in rare cases.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, irritability, anxiety, difficulty concentrating, trouble sleeping
    Urgency:
    Primary care doctor
  3. 3.Overactive Thyroid

    The thyroid is a butterfly-shaped gland in the neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid glands control how fast one burns calories and how fast the heart beats. If the thyroid is too active, it makes more thyroid hormones than the body needs. This is called hyperthyroidism.

    You should visit your primary care physician, who might take a blood test to measure your levels of thyroid hormone. The test will tell the doctor whether a referral to an endocrinologist is useful. Treatment plans would likely be set by the specialist and include drugs to reduce your thyroid activation.

    Rarity:
    Uncommon
    Top Symptoms:
    fatigue, anxiety, depressed mood, irritability, trouble sleeping
    Urgency:
    Primary care doctor
  4. 4.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
  5. 5.Hypothyroidism

    Hypothyroidism occurs when the thyroid, a butterfly-shaped organ inside the neck, no longer produces adequate levels of hormones. Thyroid hormones are essential for many bodily functions including breathing, heart rate, and metabolism.

    You should visit your primary care physician. Hypothyroidism is a complex condition that is usually treated with hormone replacement therapy.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, depressed mood, difficulty concentrating, weight gain, muscle aches
    Urgency:
    Primary care doctor

  6. 6.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.

    Call 911 immediately for an ambulance. The symptoms of atrial fibrillation can be hard to distinguish from a heart attack, so better be safe.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, chest pain, racing heart beat, lightheadedness
    Urgency:
    Emergency medical service
  7. 7.Coronary Artery Disease

    Coronary artery disease (CAD) is the most common type of heart disease. CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls.

    You contact your primary care physician today who will coordinate your care with a heart specialist (cardiologist). Treatment for CAD can involve lifestyle changes (eating healthy foods, regular exercise, weight loss, and stress reduction), medications (aspirin, beta blockers, cholesterol medications, and others), as well as surgical procedures (such as a bypass) in more serious cases.

    Rarity:
    Common
    Top Symptoms:
    fatigue, nausea, chest pain, shortness of breath, dizziness
    Symptoms that always occur with coronary artery disease:
    chest pain
    Urgency:
    In-person visit
  8. 8.Wolff - Parkinson - White Syndrome

    Wolff-Parkinson-White syndrome is a heart condition in which there is an abnormal extra electrical pathway of the heart. The condition can lead to periods of rapid heart rate.

    You should visit your primary care physician soon to confirm the diagnosis and discuss treatment options.

    Rarity:
    Rare
    Top Symptoms:
    racing heart beat, shortness of breath, deep chest pain, behind the breast bone, lightheadedness, irregular heart beat
    Urgency:
    Primary care doctor
  9. 9.Bacterial Pneumonia

    Bacterial pneumonia is the infection of the lungs with bacteria (as opposed to a fungus or a virus).

    You should go see a doctor within the next day since this diagnosis requires a chest X-ray in addition to a doctor's assessment. Treatment with antibiotics is important to keeping the infection under control, which can become dangerous if it spreads or worsens within the lungs.

    Rarity:
    Common
    Top Symptoms:
    fatigue, cough, headache, loss of appetite, shortness of breath
    Symptoms that always occur with bacterial pneumonia:
    cough
    Urgency:
    In-person visit
  10. 10.Viral (Norovirus) Infection

    Noroviruses are a group of related viruses that leads to nausea, vomiting, diarrhea, and cramps. These viruses cause gastroenteritis, an inflammation of the stomach and intestines. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids (Gatorade, Pediatlyte) to replace what is lost with diarrhea. If symptoms of dehydration occur or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

    Rarity:
    Common
    Top Symptoms:
    fatigue, abdominal pain (stomach ache), nausea, headache, stomach bloating
    Symptoms that always occur with viral (norovirus) infection:
    hidden: gastroenteritis symptoms
    Symptoms that never occur with viral (norovirus) infection:
    severe abdominal pain, throbbing headache, severe headache, tarry stool
    Urgency:
    Self-treatment
