Change in Heartbeat - Check Your Symptoms

Call 911 anytime you think you may need emergency care. For example, call if:

  • You passed out (lost consciousness).
  • You have symptoms of a heart attack. These may include:
    • Chest pain or pressure, or a strange feeling in the chest.
    • Sweating.
    • Shortness of breath.
    • Pain, pressure, or a strange feeling in the back, neck, jaw, or upper belly or in one or both shoulders or arms.
    • Lightheadedness or sudden weakness.
    • A fast or irregular heartbeat.
    After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
  • You have signs of a stroke. These may include:
    • Sudden numbness, paralysis, or weakness in your face, arm, or leg, especially on only one side of your body.
    • New problems with walking or balance.
    • Sudden vision changes.
    • Drooling or slurred speech.
    • New problems speaking or understanding simple statements, or feeling confused.
    • A sudden, severe headache that is different from past headaches.

Call your doctor now or seek immediate medical care if:

  • You have heart palpitations and:
    • Are dizzy or lightheaded, or you feel like you may faint.
    • Have new or increased shortness of breath.

Watch closely for changes in your health, and be sure to contact your doctor if:

  • You continue to have heart palpitations.
