Arrhythmia is a problem with the rhythm of the heartbeat—beating too fast, too slow, or with an irregular rhythm. Many arrhythmias are harmless, but some can be life-threatening, especially since a lack of blood flow to the body can damage the brain, heart and other organs.
Noticeable symptoms of arrhythmia include fainting, dizziness, heart palpitations, weakness, fatigue, shortness of breath and chest pain. Common causes of arrhythmias are heart disease, stress, smoking, heavy alcohol use and certain medications.
Treatment for arrhythmias depends on the type and severity of irregular heart rhythm. In most cases, people with arrhythmias can live normal, healthy lives. Always discuss irregular heart beat symptoms with your doctor.
