What is arrhythmia and what are the symptoms?
An arrhythmia is an abnormal heart rhythm that occurs when the heart’s electrical system malfunctions, causing the heart to beat irregularly or too fast. The symptoms usually include fatigue, inability to exercise, weakness, breathlessness, dizziness, fainting, and the sensation of irregular heart beat described as “palpitations.” The most common arrhythmia is atrial fibrillation (AF). Until recently treatment options were limited, leaving many patients resigned to living without their previous vigor and unable to engage in physical activities they previously enjoyed.
