Symptoms of Atrial Fibrillation
Most everyone has experienced an odd heartbeat—feeling your heart race, pound, flutter, pause or skip a beat. These episodes of unusual heart rhythm, or arrhythmia, caused by abnormal electrical impulses in the heart, are often minor and harmless. Sustained or more serious irregular rhythms, however, can pose a danger and lead to cardiac arrest.
Some people don't notice any symptoms. Others feel palpitations or a galloping or sluggish heartbeat, shortness of breath, chest pain or discomfort, fatigue or weakness, dizziness, unexplained falls or fainting. If you experience any of these symptoms suddenly or frequently, seek urgent care.
