Cardioversion is a medical procedure used to restore a normal heart rhythm in individuals who have certain types of abnormal heart rhythms, particularly atrial fibrillation (AFib) or atrial flutter.
There are two main types of cardioversion:
Electrical cardioversion: In this procedure, a controlled electric shock is delivered to the heart through pads or paddles placed on the chest. This shock briefly stops the heart’s electrical activity, allowing the heart’s natural pacemaker to regain control and hopefully establish a normal rhythm.
Chemical (or pharmacological) cardioversion: Instead of using electric shocks, medications are administered intravenously to help restore a normal heart rhythm. These medications, such as anti-arrhythmic drugs, work by affecting the electrical activity of the heart and promoting the restoration of a normal rhythm.
Cardioversion is typically performed in a hospital setting under monitored conditions to ensure safety and effectiveness. The choice between electrical and chemical cardioversion depends on various factors including the patient’s overall health, the type and duration of the abnormal rhythm, and the presence of other medical conditions.
While cardioversion can be highly effective in restoring normal heart rhythm, it’s important to recognize that it may not be a permanent solution. In many cases, additional treatments such as medications or procedures may be necessary to maintain a normal rhythm over the long term.
