Heart Rhythm Disorders
Heart rhythm disorders can be divided into three broad categories, electrical, circulatory, and structural. Cardiologists are physicians who diagnose and treat disorders of the heart. Electrophysiology is a subspecialty branch of cardiology. An electrophysiologist (EP) is highly trained in the management of electrical properties of the heart, and is the most knowledgeable doctor to deal with the many often complex options for treating heart beat, or heart rhythm, disorders.
Abnormal heart rhythms (arrhythmias) are caused by problems with the electrical system that regulates the steady heartbeat. The heart rate may be too slow or too fast; it may stay steady or become chaotic (irregular and disorganized). Some arrhythmias are very dangerous and cause sudden cardiac death, while others may be bothersome but not life threatening.
High Blood Pressure and coronary artery disease (causing blockages in the pipes (arteries) that supply blood to the heart) are the main causes of blood vessel disorders. They can result in a stroke or heart attack, which can be devastating. Fortunately, there are many preventative and treatment options.
Heart muscle disease (cardiomyopathy) and congenital abnormalities (problems in the development of the heart and blood vessels which are present from birth) are two problems that can damage the heart muscle or valves.
