Signs of Problems Related to Atrial Fibrillation

Complications Associated With Atrial Fibrillation

In addition to the symptoms explained previously, there are a number of other symptoms that can occur due to atrial fibrillation complications. Some of these complications include:
If any of the following symptoms happen suddenly, you may be having a stroke:
  • Weakness or numbness in the face, arms, or legs, especially if it's only on one side of your body
  • Loss of vision or other visual difficulties, especially if it's only in one eye
  • Difficulty speaking or understanding speech
  • Developing a severe headache for no apparent reason
  • Feeling dizzy, losing your balance, or falling for no apparent reason, especially if it happens along with the other symptoms mentioned.
If you experience any symptoms that you think are the result of a stroke, call either your doctor or 911.
Heart Attack
While atrial fibrillation by itself is rarely life-threatening, there are a few warning signs that you should be aware of that may mean you are having a heart attack (known medically as a myocardial infarction) and need urgent medical attention. The more common signs of a heart attack include:
  • Pain, pressure, tightness, heaviness, or another uncomfortable feeling in the center of your chest that lasts for more than a few minutes
  • Pain in your chest that spreads to the shoulders, neck, or arms
  • An uncomfortable feeling in your chest, along with feeling lightheaded, fainting, sweating, feeling nauseated, or having trouble breathing.
Less common symptoms of a heart attack include:
  • Pain in your neck, jaw, back, or abdomen (stomach)
  • Vomiting or feeling dizzy or nauseated
  • Feeling short of breath or having difficulty breathing
  • Feeling anxious or a sense of impending doom
  • Weakness or fatigue for no reason
  • Heart palpitations (feeling like your heart is fluttering)
  • Sweating profusely or going into a cold sweat
  • Paleness.
Some of these symptoms may also occur if you are having severe atrial fibrillation symptoms. If you experience any symptoms that you think are the result of a heart attack, call either your doctor or 911.
Serious Bleeding
Warfarin (Coumadin®) is a medicine that may be prescribed for atrial fibrillation treatment. Like all medicines, Coumadin can have side effects. The risk of experiencing side effects is higher if you are not taking the right Coumadin dosage. This is why regular blood tests and talking often with your healthcare team are so important.
Contact your healthcare provider right away if you have any unusual bleeding, for example:
  • Increased bleeding when you brush your teeth
  • Nosebleeds
  • Menstrual bleeding that's heavier than usual or unexpected
  • Blood in your feces or urine
  • Black feces
  • Vomiting up blood or something that looks like old coffee grounds
  • Coughing up blood
  • Bruising for no reason.
Other unusual symptoms include:
  • Fever
  • Diarrhea
  • Infection
  • Pain or swelling in your joints
  • Dizziness
  • Difficulty breathing
  • Sudden, severe headache
  • Chest pain
  • Feeling more weak and tired than usual.
Some of these can be signs that you have internal bleeding and may need immediate medical attention. Your dose of Coumadin might need to be adjusted as well.
