Cardioversion is a procedure used to help restore a regular heart rhythm in people with certain abnormal heart rhythms, including atrial fibrillation or atrial flutter. When the heart rhythm becomes irregular or too fast, the heart may not pump blood as efficiently. Cardioversion can help the heart return to a more regular rhythm when it is considered appropriate for the patient.

Procedure
Cardioversion
A specialized cardiac intervention performed under careful medical supervision to help manage certain abnormal heart rhythms.
Understanding the Heart Rhythm
A regular heart rhythm helps the heart pump blood effectively throughout the body. When an abnormal rhythm develops, the heartbeat may become irregular or unusually fast. Before cardioversion, the cardiologist evaluates the heart rhythm and reviews the patient’s condition to determine whether cardioversion is an appropriate treatment option.
The evaluation may include:
- Reviewing the heart rhythm
- Monitoring the heartbeat with an ECG
- Assessing the patient’s overall condition
- Identifying the type of abnormal rhythm
- Determining the appropriate approach to treatment
How Cardioversion Is Performed
1. Preparing for the Procedure
Before cardioversion begins, the medical team prepares the patient and monitors important vital signs, including heart rate, blood pressure, and heart rhythm. The patient is positioned comfortably, and the necessary monitoring equipment is connected.
2. Preparing the Chest
For electrical cardioversion, electrode pads are placed on specific areas of the chest. These pads allow the electrical energy to be delivered to the heart in a controlled manner.
3. Providing IV Sedation
Before the electrical shock is delivered, medication is given through an IV to provide sedation and keep the patient comfortable. The medical team continuously monitors the patient’s heart rhythm and vital signs throughout the procedure.
4. Delivering the Electrical Shock
Once everything is prepared, a carefully timed electrical shock is delivered through the electrode pads. The shock is synchronized with the heart’s rhythm and is intended to help interrupt the abnormal electrical activity and restore a regular rhythm.
5. Checking the Heart Rhythm
After the electrical shock, the heart rhythm is closely monitored using ECG equipment. The medical team evaluates whether a regular rhythm has been restored and continues monitoring the patient’s vital signs.
What Happens After Cardioversion?
After the procedure, the patient remains under observation while the heart rhythm and vital signs are monitored. The cardiologist evaluates the result of the cardioversion and determines the appropriate follow-up based on the patient’s condition and underlying rhythm disorder.
After Cardioversion
Following cardioversion, the patient remains under observation while the heart rhythm and vital signs are monitored. The cardiologist evaluates whether a regular rhythm has been restored and determines the appropriate next steps based on the patient’s condition and underlying rhythm disorder.
Monitoring and Follow-Up Care
Restoring the heart rhythm is an important part of treatment, but continued care may also be necessary. Depending on the underlying condition, the cardiologist may recommend medications and ongoing follow-up to help maintain a regular rhythm and manage the risk of future episodes.
Follow-up care may include:
- Monitoring the heart rhythm
- Medication management when appropriate
- Follow-up appointments with the cardiologist
- Continued evaluation of the underlying rhythm disorder
- Additional care based on individual needs
What Can Cardioversion Help Achieve?
When successful and appropriate for the patient’s condition, cardioversion can help restore a more regular heart rhythm. The result is evaluated through heart rhythm monitoring after the procedure.
The outcome may include:
- Restored regular rhythm: The heart returns to a regular rhythm after cardioversion.
- Continued monitoring: The heart rhythm may need to be monitored after the procedure.
- Medication recommendations: Medications may be prescribed depending on the underlying rhythm disorder.
- Ongoing follow-up: Continued cardiology care may be recommended to monitor the rhythm and overall heart health.
Restoring Rhythm, Continuing Care
Cardioversion is designed to help restore a regular heart rhythm when certain abnormal rhythms occur. Care does not end with the procedure. Ongoing monitoring and follow-up allow the cardiologist to evaluate the heart rhythm and provide an individualized plan for continued cardiovascular care.
