Did you know that in a study, the cardioversion rate of procedural success was 98.3% and the cardioversion death rate was 0.05% or less? This shows how effective direct current cardioversion (DCC) is for treating specific heart conditions.
The heart’s rhythm is orchestrated by an electrical system that can sometimes go awry. This can lead to atrial fibrillation, atrial flutter, and ventricular tachycardia. DCC acts as a tool in the restoration of normal heart rhythms.
In this post, we will be discussing the basics of DCC. This includes its purpose, procedure, and potential risks. So, let’s get started!
What is DCC?
DCC is a medical procedure that uses an electrical shock to restore the heart’s rhythm. It’s used to treat arrhythmias, which are abnormal heart rhythms.
During DCC, an external defibrillator or cardioverter delivers an electric shock to the chest. It’s done through paddles or patches placed on the skin. This briefly stops the heart’s electrical activity, allowing it to reset and resume its normal rhythm.
Why is DCC Done?
DCC is commonly used to treat atrial fibrillation (AFIB), where the heart’s upper chambers beat irregularly and rapidly. This can cause symptoms such as heart palpitations, shortness of breath, and fatigue.
Also, a lot of people wonder, is AFIB genetic? The short answer is yes. AFIB can be caused by genetics, as well as other factors such as age, high blood pressure, and heart disease.
DCC also be used for other types of arrhythmias. This can include atrial flutter or ventricular tachycardia. The goal is to restore a normal heart rhythm in patients with persistent arrhythmias.
Benefits of DCC
DCC has several benefits, including its high success rate and quick procedure time. Other benefits include:
Non-invasive
DCC does not require any incisions or surgery. This makes it a non-invasive procedure. This means that there is less risk of infection.
Quick Recovery
Since DCC is non-invasive, the recovery time is quick. Patients can usually go home the same day and resume normal activities within a few days.
Alternative to Medication
DCC can be used as an alternative to long-term medication. In some cases, patients may not respond well to medication or may experience side effects. DCC offers a more immediate solution.
Minimizes Stroke Risk
One significant benefit of DCC is its potential to reduce the risk of stroke. By restoring the heart’s normal rhythm, DCC can help prevent the formation of blood clots. This is a common complication in patients with atrial fibrillation.
Cost-Effective
DCC is a cost-effective option for treating persistent arrhythmias. It is a one-time procedure that can eliminate the need for ongoing medication and doctor visits. It can also help improve a patient’s quality of life by reducing symptoms and hospitalizations.
Risks of DCC
While DCC has its benefits, like any medical procedure, there are also risks involved. Some potential risks include:
Skin Irritation
The patches or paddles used during DCC may irritate the skin. This can manifest as redness, rashes, or burns. It can also lead to discomfort during the procedure.
Blood Clots
DCC can increase the risk of blood clots. This is why patients may be given blood-thinning medication before and after the procedure. It ensures that the blood flows smoothly and reduces the risk of clots.
Heart Damage
In rare cases, DCC can cause damage to the heart muscle. This can lead to scarring or weakening of the heart muscles. However, this is a very rare occurrence.
It’s important to have a skilled medical team performing the procedure to minimize this risk. Your doctor will also evaluate your medical history. They will assess any potential risks before recommending DCC.
Sedation-Related Complications
During DCC, patients are often sedated to ensure comfort and stillness. However, sedation carries its suite of risks. This can include allergic reactions, respiratory issues, and variations in blood pressure.
Thyroid Dysfunction
In some cases, DCC has been associated with the onset or exacerbation of thyroid dysfunction. The exact mechanism remains under investigation.
Patients must have their thyroid function monitored closely after undergoing DCC. This is especially important for those with a history of thyroid disease.
Procedure
The DCC procedure usually takes about 30 minutes. It is typically done under sedation to minimize any discomfort.
Preparation
Before the procedure, you may be asked to avoid food and drink for a certain amount of time. Your doctor will also review your medical history and any medications you are taking. This will help them determine the best sedative to use.
Equipment Used
The equipment for DCC includes a defibrillator and the appropriate electrodes. This can be monophasic or biphasic. The choice of monophasic or biphasic defibrillation depends on hospital protocols and the patient’s needs.
During the Procedure
During the procedure, you will lie on a table. Patches or paddles are placed on your chest and your back. The doctor will deliver the electric shock in a controlled way. They will monitor your heart rhythm throughout the procedure.
The successful execution of DCC involves choosing the appropriate energy level. It synchronizes the shock to the cardiac cycle to minimize the risk.
Unsynchronized cardioversion can also be used in emergencies. This involves delivering the shock at random times during the cardiac cycle.
After the Procedure
After DCC, your doctor will monitor you for a short period before being discharged. This is to ensure that your heart rhythm is stable. Your doctor may also prescribe medication to prevent further arrhythmias.
Post-Procedure Care
After DCC, you may experience some side effects such as fatigue or mild discomfort in the chest. This is normal and should go away within a few days.
To ensure a smooth recovery, follow your doctor’s instructions. This may include continuing any medication prescribed and avoiding strenuous activities for a short period. Be sure to attend any follow-up appointments as scheduled.
Understanding Direct Current Cardioversion
Direct current cardioversion is a common and effective procedure for treating arrhythmias. It has several benefits. This includes its high success rate and quick recovery time.
However, it’s important to understand the potential risks involved. Make sure to choose a skilled medical team for the procedure. They will provide you with all the information you need and minimize any complications.
