Cardioversion is a procedure that uses medicine or electrical shocks to correct arrhythmias. An arrhythmias is a heartbeat that is too slow, too fast, or irregular. 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.

Medicines:

You may need any of the following:

• Heart medicines help control your heart rate and rhythm.
• Blood thinners help prevent blood clots. Clots can cause strokes, heart attacks, and death. Many types of blood thinners are available. Your healthcare provider will give you specific instructions for the type you are given. The following are general safety guidelines to follow while you are taking a blood thinner:
  • Watch for bleeding and bruising. Watch for bleeding from your gums or nose. Watch for blood in your urine and bowel movements. Use a soft washcloth on your skin, and a soft toothbrush to brush your teeth. This can keep your skin and gums from bleeding. If you shave, use an electric shaver. Do not play contact sports.
  • Tell your dentist and other healthcare providers that you take a blood thinner. Wear a bracelet or necklace that says you take this medicine.
  • Do not start or stop any other medicines or supplements unless your healthcare provider tells you to. Many medicines and supplements cannot be used with blood thinners.
  • Take your blood thinner exactly as prescribed by your healthcare provider. Do not skip a dose or take less than prescribed. Tell your provider right away if you forget to take your blood thinner, or if you take too much.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Self-care:

• Rest as directed. Do not drive for at least 24 hours. Ask your provider when you can return to your normal activities.
• Check your heart rate and blood pressure as directed. Ask your provider what your heart rate and blood pressure should be.
• Do not smoke. Nicotine and other chemicals in cigarettes and cigars can cause heart and lung damage. They can also increase your risk for another arrhythmia. Ask your provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your provider before you use these products.
• Eat heart healthy foods. These include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish. Replace butter and margarine with heart-healthy oils such as olive oil and canola oil.
• Maintain a healthy weight. Ask your provider how much you should weigh. Ask him or her to help you create a weight loss plan if you are overweight.

Follow up with your doctor as directed:

Write down your questions so you remember to ask them during your visits.
