CARDIOVERSION

Your physician has recommended that you have a cardioversion to correct an abnormal rhythm known as atrial fibrillation.  This heart rhythm irregularity, also known as an arrhythmia, has continued despite use of medications to control it.  Cardioversion uses specific doses of energy in the form of a shock to the outside of your chest to correct the arrhythmia.  The energy flow will attempt to reset your heart into normal rhythm.

 Preparation

• Do not eat or drink anything for 12 hours prior to the cardioversion.
• Take you medications as usual with sips of water unless directed otherwise.
• Arrange to have a family member or friend drive you home after the procedure.

 Procedure

• You register as an outpatient and will be taken to the catheterization laboratory in the hospital.
• You will sign a consent form prior to the procedure.
• A heart monitor with ECG electrodes is connected to your chest, a blood pressure cuff is applied to your arm and an oxygen monitoring device is placed on your finger for the procedure and during your recovery.
• An intravenous (IV) line will be started and you will be given sedation to help you relax and sleep during the procedure.
• Two large patches will be applied to your chest.
• The patches are connected to a machine, called a defibrillator, which delivers the energy.
• Your electrocardiogram, heart rate, blood pressure and oxygen levels are monitored during the entire procedure.
• Once you are asleep, the physician will program the defibrillator to deliver the appropriate amount of energy to correct your arrhythmia.  It may require more than one shock to reset your heart rhythm to normal.  You will not feel anything during the procedure.
• A nurse from the hospital will call you the day before the procedure to review all instructions.

 Recovery

• You begin to awaken very shortly after the cardioversion.
• You will continue to be closely monitored in the recovery area after the procedure for approximately 2 hours.

 Results

• Your physician will speak with the person(s) who accompanied you to the hospital and to you once you are fully awakened.
• You will receive instructions regarding medications and follow-up office appointments.
• You should not plan on driving or making any legal decisions for twenty-four hours after receiving intravenous sedation.
• If you have any questions or experience any heart rhythm irregularities after the cardioversion, call the physician’s office.
