Adult Congenital Heart Disease
Adult congenital heart disease is a type of defect in one or more structures of the heart that occurs before birth. Learn about symptoms and treatment.
Bundle Branch Block
Condition in which electrical signals in the heart are blocked, causing the heart to beat out of sync.
Premature Ventricular Contraction
An occasional extra heartbeat that temporarily changes the heart's regular rhythm. The extra heartbeat originates in one of the heart's lower chambers.
Atrioventricular Block
A malfunction in the heart's electrical system that causes the heart to beat slower than it should.
Atrial Flutter
A type of abnormal heart rhythm in which the heart beats too quickly.
Sudden Cardiac Arrest
Sudden cardiac arrest occurs when the heart stops pumping, and is a leading cause of death in the United States. Learn about symptoms and treatment.
Atrial Fibrillation
Atrial fibrillation is a heart rhythm problem that causes irregular heartbeat (arrhythmia) and abnormal blood flow.
Tachycardia
Tachycardia occurs when the heart beats faster than 100 beats per minute. It can occur as a normal response to exercise, fever, stress, or other stimuli. Tachycardia that occurs abruptly and without a clear cause, or when the heart rate increases out of proportion for a given activity is considered abnormal.
Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy is an inherited condition in which the heart muscle grows thicker than it should be.
Anesthesia for Atrial Fibrillation
Patients with A-fib benefit from specialized anesthesiology. Learn more about this treatment.
