When to see a doctor. Arrhythmias may cause you to feel premature or extra heartbeats, or you may feel that your heart is racing or beating too slowly. Other signs and symptoms may be related to your heart not pumping effectively due to the fast or slow heartbeat. These include shortness of breath, weakness, dizziness, lightheadedness, fainting or near fainting, and chest pain or discomfort.
If the abnormal heart rhythm (arrhythmia) comes and goes (is intermittent), the symptoms develop suddenly, and can go just as suddenly. Symptoms can include: An abnormal awareness of your heartbeat (palpitations). But note: sensations of palpitations are also common in people who do not have an arrhythmia.
