Fact Sheets

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.
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.
Implantable Cardioverter Defibrillator
A battery-operated device that is surgically implanted in the chest to detect and correct life-threatening heart arrhythmias.
Atrial Flutter
A type of abnormal heart rhythm in which the heart beats too quickly.
Cardiac Pacemaker
A cardiac pacemaker is an implantable device that sends electrical pulses to the heart to correct a slow heart rate.
Minimally Invasive Surgery
Minimally invasive surgery is a type of surgery that involves smaller incisions and shorter recovery time. Learn more about these procedures.
Atrial Fibrillation
Atrial fibrillation is a heart rhythm problem that causes irregular heartbeat (arrhythmia) and abnormal blood flow.
Atrioventricular Block
A malfunction in the heart's electrical system that causes the heart to beat slower than it should.
Anesthesia for Atrial Fibrillation
Patients with A-fib benefit from specialized anesthesiology. Learn more about this treatment.
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.
