Abnormal Heart Rhythms (Heart Rhythm Disorders) »
The heart is a two stage electric pump whose job it is to circulate blood through the body. There is a group of cells that serve as an automatic pacemaker located in the atrium that generates an electrical current that spreads to the heart muscle cells to generate a coordinated squeeze, so that the pump can function.
The heart has four chambers, the right and left atria (singular= atrium) and the right and left ventricles. The right side of the heart pumps blood to the lungs while the left side pumps it to the rest of the body.
Blood from the body is collected in the right atrium and is pushed into the right ventricle with a small beat of the upper chamber of the heart. The right ventricle then pumps the blood to the lungs to pick up oxygen. They oxygen-rich blood returns to the left atrium where the small atrial beat pushes it to the left ventricle. The left ventricle is much thicker than the right because it needs t...

Cordarone (amiodarone) is used for many serious arrhythmias of the heart including ventricular fibrillation, ventricular tachycardia, atrial fibrillation, and atrial flutter. A generic version is available. Side effects of Cordarone include nausea, vomiting, constipation, weight loss, fatigue, pulmonary fibrosis, heart block, and heart failure.
Dosing varies depending on indication. Cordarone may interact with beta-blockers and certain calcium channel blockers resulting in an excessively slow heart rate or a block in the conduction of the electrical impulse through the heart. Cordarone increases the blood levels of digoxin, flecainide, phenytoin, and procainamide. Cordarone interacts with warfarin and increases the risk of bleeding. Amiodarone can interact with simvastatin , atorvastatin , and lovastatin , increasing the risk of severe muscle breakdown and kidney failure or liver disease. Cordarone is harmful to the fetus and to infants. It should not be administered during pregnancy and women should not breast feed while taking Cordarone.
Our Cordarone Drug Center provides a comprehensive view of available drug information as well as related drugs, user reviews, supplements, and diseases and conditions.
