Cardioversion
Cardioversion is a common and effective procedure used to restore a normal heart rhythm in people with certain types of irregular heartbeat (arrhythmia), such as atrial fibrillation or atrial flutter.
At CardioOne Brisbane, our cardiologists perform cardioversion in a safe and controlled hospital environment, ensuring comfort and precision at every step.
What Is Cardioversion?
Cardioversion involves using either electrical energy or medications to reset the heart’s rhythm back to normal (known as sinus rhythm). It’s typically recommended when an irregular rhythm is causing symptoms or reducing the heart’s efficiency.
Electrical cardioversion delivers a brief, carefully timed current to the heart through patches placed on the chest and back. The procedure is done under light sedation, so you remain asleep and comfortable.
Chemical cardioversion, by contrast, uses antiarrhythmic medication to achieve the same effect over a longer period.
Why Might Cardioversion Be Needed?
When the heart beats irregularly, it can lead to symptoms such as palpitations, breathlessness, fatigue, or dizziness. In some cases, the irregular rhythm can also increase the risk of complications such as stroke or heart failure.
Your cardiologist may recommend cardioversion if:
- You have persistent atrial fibrillation or flutter
- Symptoms are impacting your quality of life
- Other treatments (such as medications) haven’t restored a regular rhythm
Restoring normal rhythm can help your heart pump more effectively and improve overall wellbeing.

What to Expect During the Procedure
Cardioversion is usually performed in a hospital or day procedure unit. You’ll be given sedation through an intravenous line, so you’re asleep but breathing on your own. The electrical impulse is delivered through adhesive pads placed on your chest and back. The process itself takes only a few seconds.
After the procedure, your heart rhythm will be closely monitored for a short time before you go home the same day. Most patients can resume normal activities within 24 hours.
Preparing for Cardioversion
Before the procedure, your cardiologist will review your medical history and medications. You may be asked to take blood thinners (anticoagulants) for several weeks beforehand to reduce the risk of clots. In some cases, a transoesophageal echocardiogram (TOE) may be performed beforehand to check for clots in the heart.
You’ll receive clear pre-procedure instructions, including fasting and medication guidance.
After Cardioversion
It’s normal to feel a little tired or have mild skin redness where the pads were placed. Your heart rhythm will be checked before discharge, and you’ll be given a follow-up plan to monitor your heart and prevent recurrence.
Some people may need ongoing medications or other treatments to help maintain normal rhythm.
Comprehensive Arrhythmia Care
Cardioversion is just one part of managing arrhythmias. At CardioOne, our cardiologists provide ongoing assessment and care for all rhythm disorders, including long-term monitoring, medication management, and ablation procedures when needed.
If you’ve been diagnosed with atrial fibrillation or another arrhythmia, your cardiologist can help determine whether cardioversion is an appropriate next step.
