What is the procedure for cardioversion?

As a medical professional with expertise in cardiology, I can provide you with an overview of the procedure for cardioversion, which is a treatment used to restore the normal rhythm of the heart in patients with certain types of abnormal heart rhythms, known as arrhythmias. Procedure for Cardioversion: 1. Preparation: The patient is prepared by obtaining informed consent and conducting a thorough medical history and physical examination. The patient is also instructed to fast for a certain period before the procedure. 2. Medication: Sedation is often administered to ensure patient comfort. The choice of sedative can vary, but it is typically given intravenously. 3. Monitoring: The patient is connected to an ECG monitor to continuously track the heart's electrical activity. 4. Positioning: The patient is positioned on an examination table, usually lying on their back. 5. Application of Electrodes: Electrodes are applied to the patient's chest to deliver the electrical shock. 6. Synchronization: The device is synchronized with the patient's heartbeat to ensure the shock is delivered during the refractory period of the heart cycle. 7. Delivery of Shock: The electrical current is delivered in a controlled manner to depolarize the heart muscle, allowing the heart's natural pacemaker to resume control. 8. Post-Procedure Monitoring: After the procedure, the patient is monitored for any immediate complications and to ensure the heart rhythm has been restored to normal. 9. Follow-up: The patient is typically required to have a follow-up appointment to check the effectiveness of the treatment and to discuss any necessary lifestyle changes or medications to prevent recurrence.

Cardioversion is a medical procedure that restores a normal heart rhythm in people with certain types of abnormal heartbeats (arrhythmias). Cardioversion is usually done by sending electric shocks to your heart through electrodes placed on your chest. It's also possible to do cardioversion with medications.
