Cordarone

The heart’s pumping action is controlled by electrical signals that pass through the heart muscle. The electrical signals cause the two pairs of heart chambers (left and right atria and ventricles) to contract in a regular manner that produces the heartbeat. If the electrical activity in the heart is disturbed for any reason, irregular heartbeats (arrhythmias) of various types can result. These can seriously undermine the pumping action of the heart and result in inefficient blood circulation around the body. Amiodarone works by slowing down the electrical impulses in the heart muscle. This helps to regulate and restore disturbances in the heart rhythm. Amiodarone is used to treat a variety of different types of fast, abnormal heart rhythms (these are known as tachyarrhythmias). It is used for severe rhythm disorders when other treatments are not effective or cannot be used.
