What is atrial fibrillation?
Atrial fibrillation (AF) is the most common, abnormal rhythm of the heart.
The heart contracts (beats) and pumps blood with a regular rhythm, for example,
at a rate of 60 beats per minute there is a beat every second. The heart may
beat faster or slower with a shorter or longer interval between beats, but at
any one rate the interval between beats is constant. This regular rhythm occurs
as a result of regular electrical discharges (currents) that travel through the
heart and cause the muscle of the heart to contract. In atrial fibrillation, the electrical
discharges are irregular and rapid and, as a result, the heart beats irregularly
and, usually, rapidly.
Atrial fibrillation is common; half a million new cases are diagnosed yearly
in the U.S., and billions of dollars are spent annually on its diagnosis and
treatment.

Medical Editor: John P. Cunha, DO, FACOEP
Tikosyn (dofetilide) is used to help keep the heart beating normally in people with certain heart rhythm disorders of the atrium (the upper chambers of the heart). Tikosyn is used in people with atrial fibrillation or atrial flutter. It is an antiarrhythmic drug. Common side effects include headache, dizziness, or nausea.
The usual recommended dose of Tikosyn is 500 mcg twice daily. When starting, restarting, or increasing the dose, you will need to stay in the hospital for at least 3 days for monitoring. Tikosyn may interact with diuretics (water pills), HIV/AIDS medicine, drugs that can affect heart rhythm, narcotics, antibiotics, antidepressants, medicines to treat psychiatric disorders, or heart rhythm medicine. Tell your doctor all medications you are taking. During pregnancy, Tikosyn should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.

Tikosyn Consumer Information: Uses
This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as atrial fibrillation/flutter). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Dofetilide is known as an anti-arrhythmic drug. It works by blocking the activity of certain electrical signals in the heart that can cause an irregular heartbeat. Treating an irregular heartbeat can decrease the risk for blood clots, and this effect can reduce your risk of heart attack or stroke.
