Electrical Cardioversion: Helping Restore a Normal Heart Rhythm
Cardioversion uses a controlled electrical shock to reset selected abnormal rhythms. It may be planned in advance or used urgently when the circulation is affected.
Preparing for treatment
Safety checks
Cardioversion
Observation
Follow fasting instructions and ask exactly how to take your medicines. Tell the team about any missed anticoagulant doses. Arrange an adult to take you home after sedation.
Points to discuss
Use these points to prepare for your consultation.
- Is the rhythm documented on an ECG?
- Have you taken prescribed anticoagulants without missed doses?
- Has the team explained whether a clot-checking heart scan is needed?
Stroke symptoms, chest pain, collapse or severe breathlessness require emergency care.
About this treatment
Electrical cardioversion delivers a brief, synchronised shock through pads on the chest. For a planned procedure, short-acting anaesthesia or sedation is used so you are not aware of the shock. It can restore normal rhythm, but it does not guarantee that the rhythm problem will not return.
Ask your cardiologist whether cardioversion is appropriate and what preparation your rhythm requires.
When it may be recommended
Your assessment helps establish whether this option suits your condition and overall health.
- Selected atrial fibrillation where rhythm restoration is appropriate
- Certain other rapid rhythms after medical assessment
- An urgent rhythm disturbance affecting blood pressure or circulation
Your care journey
Safety checks
The team confirms the rhythm, reviews anticoagulation and checks whether additional imaging is needed.
Cardioversion
Monitoring continues while sedation or anaesthesia is given and the controlled shock is delivered.
Observation
Your rhythm and recovery from sedation are checked before the discharge and medicine plan is explained.
“Ask your care team to explain each step and the follow-up you will need.”
Benefits and risks
May restore normal rhythm and ease related breathlessness or palpitations. The electrical treatment itself is brief.
Skin irritation, sedation-related problems or a different abnormal rhythm can occur. Clot movement can cause stroke. Appropriate anticoagulation and assessment reduce this risk but do not eliminate it.
Recovery and follow-up
Many planned patients go home the same day after observation.
Follow instructions on supervision, driving and work after sedation. Continue prescribed anticoagulation for the advised duration, even if you feel better. Attend the rhythm review because AF can recur.
Stroke symptoms, chest pain, collapse or severe breathlessness require emergency care.
Questions for your consultation
- 1.What preparation reduces my clot risk?
- 2.What happens if the rhythm returns?
- 3.How long should I continue each medicine?
Not Sure What You Need?
Ask your cardiologist whether cardioversion is appropriate and what preparation your rhythm requires.
