During electrical cardioversion, a controlled electric shock is delivered to the heart through adhesive electrodes placed on the chest. This shock interrupts the abnormal electrical activity in the heart and allows the heart's natural pacemaker to regain control, hopefully restoring a normal heart rhythm. The procedure is typically performed in a controlled medical environment, and the patient is under anesthesia or sedation to ensure comfort and safety. It's important to note that electrical cardioversion is a well-established and effective treatment for certain types of irregular heart rhythms.

How is it done?

During an electrical cardioversion procedure, here's what typically happens:

1. Preparation:

• You will be asked to fast for a few hours before the procedure. This is to ensure that your stomach is empty, which reduces the risk of aspiration (inhaling stomach contents) in case you vomit during sedation.

2. Informed Consent:

• Your healthcare provider will explain the procedure, including its purpose, risks, and benefits. You'll have an opportunity to ask any questions you may have, and you'll be asked to provide your informed consent.

3. IV Line:

• An intravenous (IV) line will be started in your arm. This allows for the administration of medications and fluids during the procedure.

4. Monitoring:

• You'll be connected to monitors that continuously measure your heart rate, blood pressure, and oxygen levels. This helps ensure your safety throughout the procedure.

5. Sedation or Anesthesia:

• You may receive a sedative medication through the IV to help you relax and potentially fall asleep. In some cases, you may be under general anesthesia, which means you will be completely unconscious.

6. Electrode Placement:

• Small adhesive electrodes (pads) will be placed on your chest. These electrodes are connected to a defibrillator or cardioverter machine.

7. Setting the Machine:

• The healthcare provider will set the machine to deliver an electric shock with a specific energy level. The shock is synchronized with a specific point in your heartbeat cycle.

8. Shock Delivery:

• Once everything is prepared, the machine will deliver a controlled electric shock to your heart. This shock momentarily stops all electrical activity in the heart.

9. Monitoring and Observation:

• After the shock, the healthcare team will closely monitor your heart rhythm to see if it has returned to a normal pattern. They will also continue to monitor your vital signs.

10. Repeat Procedure (if necessary):

• In some cases, multiple shocks may be required to successfully restore a normal heart rhythm. This will be determined by your healthcare provider.

11. Recovery:

• After the procedure, you'll be closely monitored as the effects of the sedation or anesthesia wear off. Once you're awake and stable, you may be moved to a recovery area.

12. Post-Procedure Care:

• You'll receive instructions on how to care for yourself after the procedure. This may include restrictions on certain activities for a period of time.

Remember, the specifics of the procedure may vary based on individual patient circumstances and the preferences of the healthcare provider. Always follow the instructions provided by your healthcare team. If you have any concerns or questions about the procedure, be sure to discuss them with your healthcare provider.

What can I expect?

1. Medical History Review: The cardiologist will go over your medical history, including any existing heart conditions, family history of heart disease, medications you're currently taking, and any symptoms you may be experiencing.

2. Physical Examination: The doctor will perform a physical examination, which may include checking your blood pressure, listening to your heart and lungs, and examining other relevant areas.

3. Discussion of Symptoms: If you're experiencing any symptoms related to your heart, such as chest pain, shortness of breath, palpitations, or fatigue, you'll have the opportunity to discuss them in detail.

4. Diagnostic Tests: Based on your medical history and symptoms, the cardiologist may order specific tests. These could include an electrocardiogram (ECG), echocardiogram, stress test, or other specialized cardiac tests.

5. Interpretation of Test Results: The cardiologist will review the results of any tests and discuss their implications for your heart health.

6. Diagnosis: Based on the gathered information and test results, the cardiologist will make a diagnosis. This could range from confirming a previously known heart condition to identifying a new issue.

7. Treatment Plan: If necessary, the cardiologist will discuss treatment options. This could involve medications, lifestyle modifications, procedures, or surgeries.

8. Education and Recommendations: The cardiologist will provide you with information about your condition, explain any necessary lifestyle changes, and offer guidance on managing your heart health.

9. Follow-Up Plan: Depending on your diagnosis and treatment plan, you may be advised to schedule follow-up appointments for further evaluation and monitoring.

10. Addressing Questions and Concerns: You'll have the opportunity to ask any questions or express concerns you may have about your heart health.

11. Referrals: If specialized care is required, the cardiologist may refer you to other healthcare professionals, such as cardiac surgeons or electrophysiologists.

12. Medical Records: Your visit and the details discussed will be documented in your medical records.

Remember, each visit may vary based on your specific situation, and the cardiologist's approach. It's important to be open and honest about your symptoms and medical history. This will help the cardiologist make the most accurate assessment of your heart health and provide you with the best possible care.
