Cardioversion is a procedure that uses electrical shocks to reset an abnormal heartbeat to a normal rhythm. It is a generally safe procedure that is used to treat atrial fibrillation, atrial flutter, and other abnormal heart rhythms. While the procedure is not painful, as it is performed while the patient is asleep, there are some risks and complications that can occur. These include blood clots, sedation effects, site pain, burns, and hypotension. In rare cases, lumbar compression fractures have also been reported as a complication of cardioversion, which can result in severe back pain and other neurological symptoms.

Cardioversion is a procedure to correct abnormal heart rhythms
Cardioversion is a procedure used to correct an abnormal heartbeat and restore a normal rhythm. It is performed when the heart is beating too fast or irregularly, a condition known as arrhythmia. This condition can cause serious problems such as fainting, stroke, heart attack, or even sudden cardiac death.
During the procedure, a healthcare provider uses a device or medicine to change the patient's heart rhythm. The procedure can be performed as an emergency if symptoms are severe, or it can be scheduled in advance. Before the procedure, patients are given detailed instructions, including the need to have someone drive them home as they will be unable to drive for 24 hours afterward. Patients may also be instructed to take certain medications, such as blood thinners, and to fast after midnight on the day of the procedure.
During cardioversion, the patient lies on a bed, and an intravenous (IV) line is started in their arm or hand to administer medications and fluids. Electrocardiogram (EKG) patches and adhesive cardioversion pads are placed on the patient's chest and sometimes their back, delivering specific amounts of energy to the heart. The procedure is performed while the patient is asleep, and their oxygen level, heart rhythm, and blood pressure are monitored.
Cardioversion is generally safe and effective, but there are some risks associated with the procedure, including the possibility of a more dangerous heart rhythm developing, blood clots, and a return to an abnormal rhythm shortly after the procedure. Other potential complications include skin rashes or burns, bruising from the IV, and allergic reactions to medications.

It can cause lumbar compression fractures and back pain
Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is generally considered safe and is used when the heart is beating too fast or irregularly (arrhythmia). Cardioversion can be performed as an emergency procedure or as a scheduled operation. During the procedure, the patient is asleep as a machine delivers specific amounts of energy to the heart through cardioversion pads.
Although rare, there are some risks associated with cardioversion. These include:
- Blood clots in the heart breaking loose and causing a stroke
- Allergic reactions to medication
- Skin damage from electrodes or burns
- Bruised skin from an IV
- Worsening of abnormal heart rhythm
In addition to these complications, there is also a rare chance of lumbar compression fractures and back pain. Lumbar compression fractures are typically caused by osteoporosis or trauma, such as from falls or accidents. However, in very rare cases, they have been associated with electrical energy from defibrillation.
A case study describes a 46-year-old man who experienced a lumbar compression fracture and severe back pain after undergoing synchronized cardioversion. The pain was so severe that he was unable to sleep or tolerate pressure against the L1 vertebra. He also developed progressive L1-L2 bilateral sensory neuropathy, which spread to his thighs and testicles. The pain eventually subsided after seven weeks of treatment with gabapentin.
This case highlights a potential major adverse effect of cardioversion that should be considered in the consent process and differential diagnosis of post-procedural back pain. While lumbar compression fractures from cardioversion are rare, they can have significant consequences and require appropriate recognition and management.

Cardioversion may lead to clot dislodgement, stroke, and heart failure
Cardioversion is a procedure used to return an abnormal heartbeat to a normal rhythm. This procedure is generally safe and is used when the heart is beating too fast or irregularly, a condition called arrhythmia. Arrhythmias can cause serious problems such as fainting, stroke, heart attack, and even sudden cardiac death. While cardioversion is a safe and commonly used procedure, it does carry some risks, including the possibility of clot dislodgement, stroke, and heart failure.
During cardioversion, a high-energy shock is delivered to the heart to reset its normal rhythm. This shock can dislodge any existing clots in the heart, which could potentially lead to a stroke. To mitigate this risk, a transoesophageal echocardiogram is typically performed before the procedure to ensure that no clots are present within the heart. Additionally, patients are often given medications before and after the procedure to help prevent clotting.
Cardioversion can also lead to heart failure in rare cases. This can occur if the procedure results in a more dangerous heart rhythm, which can further deteriorate heart function. In such cases, healthcare providers may administer additional medications or a stronger electric shock to restore a normal heart rhythm and prevent heart failure.
Furthermore, cardioversion can increase the risk of stroke, especially in patients with atrial fibrillation (AFib). AFib is a condition where the atria of the heart quiver instead of beating correctly, leading to an increased risk of stroke. Cardioversion is often recommended for patients experiencing AFib for the first time to reduce this risk. However, it is important to note that the procedure may not always be successful in resetting the heart rhythm, and the abnormal rhythm may return shortly after the procedure.
In conclusion, while cardioversion is a safe and effective procedure for treating abnormal heart rhythms, it carries a small risk of clot dislodgement, stroke, and heart failure. Healthcare providers carefully monitor patients and take necessary precautions to minimise these risks. Patients are also typically given detailed instructions before the procedure and may need to continue certain medications before and after the cardioversion to prevent complications.

Sedation effects, burns, and skin damage are potential risks
Cardioversion is a procedure that uses a cardioverter machine (defibrillator) to deliver specific amounts of energy to the patient's heart through cardioversion pads. This process restores a normal heart rhythm by interrupting the abnormal electrical rhythm. Cardioversion is performed while the patient is asleep, so they do not experience any pain during the procedure.
Sedation effects are a potential risk of cardioversion. The patient needs to be unaware of the procedure as it is painful and distressing. The drugs used should induce a rapid loss of consciousness and should not have cardiovascular, respiratory, or other side effects. Anaesthetic or sedative agents are used to achieve this state, with some common drugs being propofol, etomidate, and midazolam. However, the specific drug choice depends on the patient's condition and the clinician's preference, as there are currently no standard guidelines for drug selection in cardioversion. While few people recall the procedure, the advantage of amnesia should be weighed against the increased risk of airway problems and respiratory or cardiovascular instability.
Burns and skin damage are also potential risks of cardioversion. Cutaneous burns are a common complication, and their incidence and severity have been quantified in studies. Patients may experience pain, with 84% of patients in one study reporting some pain, and 23% experiencing moderate to severe pain. The pain and severity of burns are related to the total energy delivered and the number of shocks. To minimise burns, operators should apply equal paddle force to both paddles, ensuring even contact along their edges. Starting with lower energy shocks can also reduce the risk of burns. Additionally, topical steroid creams may be used to mitigate the severity of cutaneous burns.

Cardioversion is generally safe and effective for treating atrial fibrillation
Cardioversion is a procedure that can be used to treat atrial fibrillation and restore a normal heart rhythm. It involves delivering a specific amount of energy to the heart through cardioversion pads, which interrupt the abnormal electrical rhythm and restore a normal one. The procedure is generally safe and effective, and around 30,000 cardioversion procedures are performed annually in the United States for atrial fibrillation alone.
Cardioversion can be performed using medicines or an electric device. In electrical cardioversion, soft electrode patches are placed on the patient's chest and back, and they are connected to a cardioversion machine. The patient is given medication to help them fall asleep during the procedure. The machine then delivers a high-energy shock to the heart, which resets the normal rhythm. It may take several shocks to achieve this, but the patient will not feel any pain as they will be asleep.
Electrical cardioversion is commonly used to treat atrial fibrillation, atrial flutter, and other abnormal heart rhythms. It is particularly useful for those experiencing atrial fibrillation for the first time or those with severe symptoms. The procedure can help to reduce the risk of stroke and is generally successful in 67% to 91% of cases, with variability depending on the amount of energy delivered and the duration of symptoms.
While cardioversion is considered safe, there are some potential risks and complications that can occur. These include clot dislodgement, sedation effects, site pain, burns, hypotension, dysrhythmias, and heart failure. However, these complications are not common, and healthcare providers will closely monitor patients during and after the procedure to ensure their safety. Overall, cardioversion is a valuable treatment option for atrial fibrillation, offering a safe and effective way to restore normal heart function and reduce the risk of serious complications such as heart attack or stroke.
