What is Cardioversion?

Cardioversion is a medical procedure that is done to restore a normal heart rhythm in people with an abnormal rhythm, also known as arrhythmia. It is done by providing electrical shocks to the heart through electrodes placed either on the chest or through paddles held against the chest. This shocks the heart and helps to reset the rhythm. It can be done in an emergency room or in the hospital with the patient being sedated or unconscious.

Cardioversion is used to treat many different types of arrhythmias. It can be used to treat atrial fibrillation (AFib), atrial flutter, supraventricular tachycardia (SVT), ventricular tachycardia (VT), and some forms of ventricular fibrillation (VF). All of these arrhythmias can cause symptoms such as a rapid or irregular heartbeat, or palpitations. Cardioversion can help restore a normal rhythm in these cases.

What Does the Procedure Involve?

When a patient is undergoing cardioversion, they are usually sedated to help make sure that they don’t feel any discomfort. Then, two electrodes will be placed on the chest. These electrodes are used to deliver an electrical shock, similar to the shock you would feel if you touched an outlet. This shock helps to reset the heart’s rhythm.

In some cases, a medication, such as amiodarone or ibutilide may be given before the shock to help convert the rhythm. After the shock, the patient’s heart rate and rhythm will be monitored to make sure the procedure is successful.

Is Cardioversion Safe?

Cardioversion is generally a safe procedure, but like any medical procedure there can be some risks. These risks include bleeding, infection, tissue damage, and cardiopulmonary arrest. It is important to talk to your doctor about any concerns before the procedure is performed.

In addition, cardioversion may not always be successful. Sometimes, the heart rhythm will revert back to the arrhythmia after the procedure. In these cases, if it is determined by your doctor, medication or another procedure such as ablation may be used to help restore the normal rhythm.

Conclusion

Cardioversion is a safe, effective way to restore a normal heart rhythm in people with an irregular rhythm. It is usually done as an outpatient procedure with the patient being sedated. While there can be some risks involved, these can be discussed with your doctor before the procedure is performed. If cardioversion is successful, it can help reduce symptoms and improve quality of life.
