    Preparing for Electrical Cardioversion: What to Expect?

    When faced with a medical procedure like cardioversion, it’s natural to have questions and concerns about its safety and potential risks. One pressing question that often arises is, “Can you die during cardioversion?” It’s a valid query because it deals with matters of the heart. In this comprehensive guide, we will address this important question and provide you with a thorough understanding of the electrical cardioversion process.

    Understanding Electrical Cardioversion

    Electrical cardioversion is a medical process by which a range of heart rhythm disorders are treated. These heart conditions cause the heart to beat faster or with irregularity. The cardioversion procedure delivers controlled electric signals to the heart to regulate the heartbeats. While the thought of an electrical shock to the heart may sound intimidating, cardioversion is a safe and well-established medical intervention performed by trained healthcare professionals like the Cardiovascular Group.

    The heart relies on electric signals generated by the body to beat correctly. However, in some cases, these electrical impulses can lose rhythm and malfunction, leading to irregular heartbeats. These irregular heartbeats, resulting from atrial fibrillation or atrial flutter, can result in other signs and symptoms like shortness of breath, dizziness, and fatigue. Cardioversion is recommended when other treatment options like medications (for example, blood thinners) fail to return the heart to a normal heartbeat pattern (also called sinus rhythm).

    Cardioversion requires specialized equipment that delivers controlled electrical impulses to the heart. These shocks disrupt the malfunctioning electric signals emitted by the heart and “reset” the heart’s electrical system. The result is a return to normal heart rhythms. This procedure can restore the heartbeat pattern to the normal level almost instantly. In addition to this, it also minimizes the risk of stroke and blood clot formation. These factors make cardioversion successful in treating conditions like atrial fibrillation or atrial flutter.

    Contacting Your Doctor or Healthcare Provider

    If you feel you are experiencing irregular heartbeat symptoms (arrhythmia), immediately consult your doctor. They will critically analyze your condition and suggest treatment options, including the possibility of external or internal cardioversion. Contacting a doctor or other healthcare professionals in this situation is always recommended. They provide you with an accurate medical diagnosis, especially in cases where it can overlap with similar conditions. They can personalize special treatment plans for you according to your medical condition, considering factors such as your overall health, medical history, and the severity of your heart rhythm disorder. In addition, they will assess your risk factors and discuss the potential benefits and risks associated with the procedure.

    Before your appointment with the doctor, list all the symptoms you have been facing, their severity, and their timings. Also, note any prior medical conditions, your medical history, and any medications you may be taking. You must ask and thoroughly question your doctor for more clarity. Your doctor is there to provide information, address your worries, and guide you through the decision-making process. Before making a decision, consider any considerations for the cost of the treatment. Contact your health insurance provider to discuss your insurance coverage and any financial aspects of the procedure. Also, consider any alternative treatment and choose the one you feel suits you better.

    Medical Evaluation and Testing

    After consultation with your doctor, the next step is to conduct a comprehensive medical evaluation and testing. This step is critical to assess your general health and the specificities of your heart condition. Or any other conditions that may affect the procedure.

    The importance of these tests and evaluations can’t be stressed enough. They dictate crucial treatment decisions by giving the doctor an accurate idea of your heart condition. The overview of your health and any associated risk factors help your medical team determine the feasibility of the process and the suitable anesthesia or sedation levels. The results of these tests inform the development of a personalized treatment plan. Your healthcare provider can tailor their approach to your unique medical history and condition.

    Here are some of the tests that you may encounter:

    • Electrocardiogram (ECG or EKG): This painless test is used to see the beating patterns of your heart. It provides an idea of your heart’s sinus rhythm or any irregular rhythms.
    • Echocardiogram: This test helps to create an image of your heart using ultrasound waves. This helps see the function and structure of your heart, including some structural abnormalities.
    • Blood tests: Blood tests give an idea of your overall health, including levels of electrolytes, kidney function, and blood clotting factors.
    • Chest X-ray: Help to identify any lung or heart issues that may interfere with the main procedure.
    • Thyroid Function Tests: Thyroid imbalances can contribute to atrial fibrillation. Your thyroid function may be evaluated through blood tests.

    Medication and Health History

    You will be required to provide your current medication routine and a detailed health history before embarking on a cardioversion recovery. This is a crucial step that helps mitigate any side effects of cardioversion and ensures that the treatment plan is tailor-made to cater to your personal health needs.

    Certain medications contain drugs and ingredients that can affect the anesthesia or sedation process. Reviewing the medication schedule helps to make necessary adjustments for the duration of the recovery process and for the time immediately before that. In addition to this, studying your health history may help to flag any underlying conditions that need to be considered before the procedure. These include structural heart diseases, pulmonary conditions, hypertension, diabetes, and some thyroid disorders like hyperthyroidism and hypothyroidism. Therefore, an accurate medication list and health history contribute to the overall safety of the cardioversion process. This information helps doctors in anesthesia, sedation, and post-procedure care decisions.

    NPO Guidelines: Fasting Before Cardioversion

    Fasting before the procedure is a critical step necessary to ensure your safety during the procedure. NPO, which stands for “nil per os,” means “nothing by mouth” in the English language. This is a common requisite for any procedure that requires the use of anesthesia to keep your stomach empty.

    There are many benefits of fasting before anesthesia. It helps to minimize the risk of vomiting and aspiration (inhaling stomach contents into the lungs) while you are sedated or under anesthetics during the process. In addition to this, an empty stomach allows for better visuals during tests and the actual procedure of cardioversion, maximizing the effectiveness of the process. Moreover, fasting can also help you feel better by avoiding any chance of nausea, which is common during the administration of anesthesia or sedatives.

    There are set fasting guidelines that you must follow before going for cardioversion. Normally, patients are advised not to consume any eatables, milk, or opaque liquids 6-8 hours before the procedure. However, clear liquids like water, apple juice (without pulp), and clear broth are usually allowed up to 2 hours before the procedure. In some cases, you may not be allowed to take any medications just before cardioversion; however, exceptions can be made for some essential medicines. Moreover, you may be asked to avoid any alcohol or smoking for as long as 24 hours before the procedure. It is always recommended to drink water as dehydration can complicate the procedure and subsequent recovery.

    Understanding Anesthesia Options

    Anesthesia ensures your comfort during the procedure. The anesthesia and sedation options available may vary according to your specific needs and health status. The type of anesthesia chosen depends on factors such as your health, the complexity of the procedure, and your preferences. The common types of anesthesia options available for this type of procedure are general anesthesia, deep sedation, and conscious sedation.

    Under general anesthesia, you are completely unconscious and unaware of your surroundings. Important medicines may be delivered using an intravenous drip. To support your breathing, a breathing tube may also be installed. This type is generally used for longer or more complex procedures.

    Conscious sedation is a less severe form of anesthesia. You remain awake and are fully aware of your surroundings. You are able to respond to remarks and instructions. However, you are deeply relaxed and may have very little memory of the procedure. This is the type that is generally used for electrical cardioversion. Deep sedation, on the other hand, is the middle way between general anesthesia and deep sedation. It doesn’t render you completely unconscious, and you may be less aware of your surroundings and less responsive generally.

    Preparation in the Cardioversion Room

    On the day of the final procedure, make sure that you arrive at the medical center on time. Punctuality allows the healthcare team to coordinate their efforts efficiently, ensuring that all aspects of the procedure go according to plan. After check-in and some necessary paperwork, you’ll be asked to change into a medical gown, and an intravenous line may be set up on your arm for quick administration of anesthesia and medicines. Arriving at the center can be anxiety-inducing for some patients. If you’re feeling nervous, the healthcare team is there to offer emotional support and reassurance.

    Now you are ready for the main procedure. The cardioversion room is a specialized space where the procedure will take place. It is a sterile environment with the necessary medical equipment and monitoring devices. The room is designed for a comfortable experience, with facilities like adjustable lighting and temperature. A blood pressure monitor and a pulse oximeter will be used to monitor and record your blood pressure and heart rates. In addition to this, final preparation for the process will begin, including the administration of anesthesia or sedation.

    The Cardioversion Process

    Here is how the final procedure happens:

    1. The staff ensures you are correctly positioned for easy access to the medical equipment.
    2. Then, special electrode pads are placed on your chest. These pads are connected on the other end to a cardioversion machine.
    3. The staff will then ensure you are receiving proper sedatives or medicines before the process starts. This is done to minimize any discomfort or awareness during the procedure.
    4. A shock delivery will be done and transmitted using the electrode pads attached to you. The controlled shock signal will disrupt the current heartbeat rhythm and restore the heart’s electrical signals, and the normal rhythm will be restored.
    5. After the initial shock, the staff will monitor your heart activity and ensure that the normal rhythmic pattern has been restored. Any additional shocks will be administered if needed to bring it back to normal.

    A frequently asked question is, “How many times can you have electrical cardioversion?” There is actually no limit, and this can be done until a patient gets frustrated from the process, in which case an alternative treatment must be used. For more information about the steps leading up to the procedure or general queries, contact your doctor.


    In this comprehensive guide, we’ve walked you through the essential steps in preparing for electrical cardioversion. Remember that cardioversion is a well-established and effective treatment for certain heart disorders like atrial fibrillation. Your healthcare team is dedicated to ensuring your safety and comfort throughout the process. Make sure that you follow their instructions before, during, and after the process.
