Chemical Cardioversion

You had cardioversion today. In this procedure, a medicine was put into one of your veins. Or it was given to you to take by mouth (orally). This caused your heart to go back to a normal rhythm. In most cases, you should feel back to normal by the time you go home.

Home care

Follow these guidelines when caring for yourself at home:

• You can go back to your usual activities once you feel back to normal.

• Your healthcare provider may prescribe medicines to stop the abnormal heart rhythm from coming back. Take these medicines as directed. If you have certain rhythm problems such as atrial fibrillation or atrial flutter, you may need take blood thinners for at least 4 weeks after a cardioversion. If possible, don't schedule any surgeries or dental procedures during this time. This is so you won't have to stop taking the blood thinners. Stopping the medicines can raise your risk for stroke.

Follow-up care

Follow up with your healthcare provider, or as advised. You may need more testing. This might be an echocardiogram or event monitor. An event monitor checks your heart rhythm. Not all people with irregular heart rhythms have symptoms.
