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.

Atenolol Drug Center
Medical Editor: Charles Patrick Davis, MD, PhD
Tenormin (atenolol) (and Tenormin IV) is a beta blocking drug used mainly for control of hypertension, angina, for management of acute myocardial infarction and occasionally for thyroid storm management. Tenormin is available as generic atenolol in tablets and IV. Side effects of Tenormin may include dizziness, lethargy, mild bradycardia, depression, and mild shortness of breath for both preparations. Patients with bronchospastic disease, in general, should not take Tenormin or other beta-blockers.
Tenormin is available in 25, 50 and 100 mg strength tablets; it is also available vials of 5 mg atenolol in ten ml of citrate-buffered solution for intravenous injection. The IV preparation should only be administered by trained personnel. The usual dose for tablets begins at 25 mg once or twice per day and is modified by patient response to the medication. The following information applies to both the tablet and IV forms of atenolol. Serious side effects of Tenormin may include heart arrhythmias, hypotension, pulmonary emboli, chest pain, and bronchospasm. Use with calcium channel blockers (CCBs) may precipitate bradycardia. This medication should be used during pregnancy only when clearly needed. It may harm an unborn baby. This medication passes into breast milk and may have undesirable effects on a nursing infant. Consult the doctor before breastfeeding. Women taking Tenormin should discuss the risks and benefits with their doctor. Safety and effectiveness has not been established in pediatric patients.

Atenolol Consumer Information: Uses
Atenolol is used with or without other medications to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This medication is also used to treat chest pain (angina) and to improve survival after a heart attack.
Atenolol belongs to a class of drugs known as beta blockers. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart.
