Top 6 Irregular Heart Beat Causes

  1. 1.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:
    Common
    Top Symptoms:
    fatigue, shortness of breath, chest pain, racing heart beat, shortness of breath on exertion
    Urgency:
    Emergency medical service

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

    Rarity:

  4. 4.Sick Sinus Syndrome

    Sick sinus syndrome is a series of conditions related to changes of the electrical system in the heart as one ages. This causes a slower heart beat at different times.

    You should visit your primary care physician, where an ECG can measure the electrical rhythms of the heart and potentially identify Sick Sinus Syndrome. Otherwise, your doctor may use a longer term monitoring device. Treatment is only for severe cases and involves a pacemaker.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, racing heart beat, lightheadedness, shortness of breath on exertion
    Urgency:
    Primary care doctor
  5. 5.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.

    If you are an otherwise healthy individual, there's generally no reason for concern as PVC's on themselves are not harmful. However, palpitations can be hard to distinguish from a more serious underlying heart issue, and therefore it is recommended to visit a doctor today to get an EKG done.

    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
    Symptoms that always occur with premature ventricular contractions:
    racing heart beat
    Urgency:
    In-person visit
  6. 6.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
