Electrical cardioversion uses a brief electric shock to reset an abnormal heart rhythm (like atrial fibrillation).
What to Expect
- The Setup: The doctor places patches on your chest (and sometimes your back).
- The Shock: These patches send a brief electric current to your heart to restore normal rhythm.
- The Sensation: You will be given medicine to make you sleep, so you should not feel any pain.
- The Timing: The shock itself lasts only a few seconds, but plan to be at the hospital for several hours to allow time for preparation, sedation, monitoring, and recovery.
Preparation Checklist
Planning Ahead
- The Ride: You CANNOT drive yourself home due to the sedation. Arrange a driver.
- Medications: Ask your doctor specifically about blood thinners (aspirin, anticoagulants). Tell them about all supplements and herbs.
- Documents: Bring a copy of your Advance Directive and your ID.
Day of Procedure
- Fasting: Stop eating and drinking exactly when instructed. (If you must take meds, use only a small sip of water).
- Hygiene: Shower beforehand. Do not apply lotions, perfumes, or deodorants (these affect the patches).
- Items: Remove all jewelry, piercings, and contact lenses.
Important: Medication Review
Some medicines or supplements can increase risks during the procedure. Make sure you understand exactly what your doctor wants you to stop taking and when.
When to Call Your Doctor
Contact your provider before the procedure if:
- You become ill (fever, flu, or cold).
- You have questions about how to prepare.
- You need to reschedule.
