Electrophysiology is the branch of cardiology that deals with the electrical impulses, or the rhythms of your heart. If you have an abnormal heart rhythm (an arrhythmia), your heart rate is abnormally fast, slow or even irregular. “Normal” heart rates differ dependent upon your age, activity level, medications you may be taking, as well as any preexisting heart conditions that you may have.

There are a variety of symptoms that may be caused by arrhythmias ranging from a simple awareness of your heart beating, to lightheadedness, blurred vision, or cardiac arrest. Other symptoms include chest pain, shortness of breath, dizziness and fainting. The symptoms that occur depend on your heart rate during the arrhythmia, your activity at the time of the arrhythmia, and the possibility of structural heart problems. Your physician will discuss your symptoms with you extensively. Testing and treatment will be determined based on your doctor’s assessment of your symptoms.

There are many types of arrhythmias and their significance and treatment depends on the exact type. To better understand the different types of arrhythmias, it would be helpful to first understand how the heart works and the heart's normal electrical system.
