A.I. Health Assistant Causes for Slow Heart Rate

Updated on Aug. 29, 2018

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

  1. 1.Third Degree Atrioventricular Nodal Block

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

    Indefinite

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

    Unfortunately, chemotherapy has many side-effects, ranging from hair loss to fatigue to nausea. This occurs because the treatment affects not only diseased cells but also healthy cells.

    This is likely to last the duration of your treatment; however, symptoms can be managed with other medications.

    Rarity:
    Uncommon
    Top Symptoms:
    fatigue, loss of appetite, arthralgias or myalgias, dizziness, sore throat
    Symptoms that never occur with side-effect(s) of chemotherapy:
    headache resulting from a head injury
    Urgency:
    Primary care doctor
  3. 3.Heart Attack

    Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart.

    Indefinite

    Rarity:
    Uncommon
    Top Symptoms:
    chest pain, shortness of breath, tight, heavy, squeezing chest pain, being severely ill, nausea
    Urgency:
    Emergency medical service

  4. 4.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.

    Most cases of hypothyroidism require lifelong hormone replacement therapy.

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

    The myocardium is the muscular tissue that makes up the walls of the heart, allowing it to contract and push blood throughout the body. Myocarditis is the condition when this muscular tissue becomes inflamed, often as a result of an infection, causing the heart to struggle to pump blood.

    If myocarditis has not damaged the heart too much, expect a 2-3 week course of medication to treat infection.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, headache, shortness of breath, muscle aches, chest pain
    Urgency:
    Hospital emergency room
  6. 6.Beriberi (Adult)

    A low level of vitamin B1 (thiamin) can cause damage to the heart, brain and nerves. This can result in symptoms like weakness, amnesia, nerve pain and symptoms of heart failure like swelling of limbs and shortness of breath.

    Symptoms may resolve if treatment is started promptly, however some patients will experience persistent symptoms.

    Rarity:
    Ultra rare
    Top Symptoms:
    abdominal pain (stomach ache), shortness of breath, anxiety, chest pain, distal numbness
    Urgency:
    Hospital emergency room
  7. 7.Moderate to Severe Hypothermia

    With prolonged exposure to freezing cold, the body can lose the ability to maintain a safe core temperature. If this continues for long enough, you can become confused or even lose consciousness

    If hypothermia is severe enough, death or permanent disability can occur

    Rarity:
    Ultra rare
    Top Symptoms:
    coldness, alertness level change, pale skin, slow heartrate (under 60bpm)
    Symptoms that never occur with moderate to severe hypothermia:
    shivering
    Urgency:
    Emergency medical service
