Prior : Prior to recieving a cardioversion, your health care provider needs to ensure that there are no clots in the heart. If there is a clot in the heart at the time of the cardioversion, the patient is at high risk for suffering a stroke or a heart attack. Upon the diagnosis of arrhythmia, a patient will be placed on a blood thinning regimen, typically 4-6 weeks prior to undergoing a cardioversion. (a blood test can be performed to ensure your levels are in 'therapeutic' range). However, the presence of clots anywhere in your body and heart could cause the cardioversion procedure to be postposed. Talk to your health care provider about why your procedure has been held.

4 weeks: 4 weeks before and 3 weeks after at a minimum. This is the standard of care. Alternatively, you can undergo transesophageal echo. If that shows no clot, you can proceed immediately but still must take medication for at least 3 weeks afterward.

4 weeks: You must be therapeutically anticoagulated for 4 weeks before undergoing elective cardioversion and then stay on the medication for an additional 3 weeks at a minimum.

Upon : Upon onset of atrial fibrillation, it will be important for you to be on blood thinners for 4 to 6 weeks to ensure there are no blood clots present in the heart prior to procedure. If there is a blood clot in your heart during the cardioversion procedure, the risk for heart attack and stroke are very high. While on blood thinners, you will have regular appointments to have your blood drawn to ensure therapeutic ranges in the blood. The following blood tests will be assessed: protime and inr, which test how think your blood is. If at anytime, your blood levels are not in therapeutic range (too high - high risk of bleeding or too low - high risk for clot), your dosage of blood thinners will be adjusted.
