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.
About tachycardia, the fast beat. Tachycardia is a rapid heart rate that is faster than 100 beats per minute, and it causes the heart to work too hard. This means that the heart does not have enough time to fill and that not enough blood is being pumped forward. This results in symptoms including palpitations, chest pain, dizziness and fainting.
