WHAT YOU NEED TO KNOW:
What is a chemical cardioversion?
Chemical cardioversion is a procedure to give you medicine to correct an arrhythmia. An arrhythmia is when your heart beats too fast or irregularly. It may prevent your body from getting the blood and oxygen it needs. Your heart has 4 chambers, called the atria and ventricles. The atria are at the top of your heart, and the ventricles are at the bottom of your heart. Most arrhythmias that need cardioversion start in the atria.
How is a chemical cardioversion done?
You may need blood thinners or other medicines before and during the procedure. These may help prevent a clot caused by an arrythmia. The cardioversion chemical will be put into your IV. You may need more than one dose of the chemical to help your heart rhythm return to normal. If the chemical cardioversion does not work, you may need an electrical cardioversion. Electric pads or paddles are used to give your heart an electric shock. This shock may reset the heart and return it to a normal beat.
What are the risks of chemical cardioversion?
Chemical cardioversion may cause other heart or blood pressure problems. Even with cardioversion, your heartbeat may not return to or stay in a normal rhythm. Some arrhythmias may cause a blood clot to form in your heart. The clot may travel to other parts of your heart or brain and cause life-threatening problems, such as a heart attack or stroke. If untreated, some arrhythmias can increase your risk of heart failure or a heart attack.
