Pre admission preparation
IMPORTANT: You must continue to take all your medications
Anticoagulant (blood thinning tablets): If you are currently taking one of the newer agents for anti-coagulation called a NOAC/ DOAC i.e. (Apixaban, Edoxaban, Rivaroxaban or Dabigatran).
It is paramount not to miss a single dose of it within 4 weeks leading up to the cardioversion. Should this occur please call us and we will reschedule the procedure. If this is the case and you attend we will cancel the procedure due to an increased risk of stroke.
Warfarin, Acenocoumarol, Phenindione: Your INR will be checked, this needs to be between two and three for four consecutive weeks leading up to the Cardioversion. If drops below two your cardioversion will be cancelled and rearranged.
Digoxin: Please stop 2 days prior to procedure if taking
- During the week of the appointment you will receive an appointment date through the post to attend for an ECG at your local Cardiorespiratory Department along with a request to have your bloods taken on the same day. This could be at Doncaster, Mexborough or Bassetlaw Hospital.
- You should arrange transport home with a relative or a friend as you will not be allowed to drive home after the procedure.
- Bring with you a dressing gown, slippers and your medications.
The day of the procedure
You must not eat or drink anything six hours before your admission.
On arrival to the Ward
You will be assessed by a Nurse. You will also be seen by the Anaesthetist and the Doctor in charge of your care.
The Doctor will explain the procedure and ask you to sign a consent form agreeing to the procedure and confirming that you have continued to take your anti-coagulant (blood thinning) tablets for at least four weeks and haven’t missed any doses.
You will be given a gown to wear for the procedure.
What does the procedure involve?
You will lie on a trolley and the nurse will attach you to a defibrillator by three monitor leads and two cold sticky pads (defibrillator pads) to your chest and back.
A blood pressure cuff will be applied to your upper arm. Both are required so that your heart and blood pressure can be monitored throughout the procedure.
A cannula (a Hollow plastic tube) will be inserted into a vein in the back of your hand or in your arm, this is to enable a short-acting sedation to be administered by an anaesthetist.
An Oxygen mask will be placed over your nose and mouth. Once asleep, a low-voltage electrical shock is administered by the Doctor to the chest wall in order to correct the heart rhythm.
A maximum of three shocks can be given. In most cases this procedure is effective, but the abnormal heart beat can recur and your doctor will monitor this.
After the cardioversion, you will be advised on which medications need to be continued. Alternative medication may be suggested if the procedure has not been successful.
You will feel tired and drowsy following the anaesthetic and should expect to rest in hospital for two to three hours.
Will it work?
There is about a 90% chance that this procedure will return your heart to normal rhythm at the time.
However depending on the underlying condition and your drug treatment there is a possibility that even if successful you may revert to your original rhythm within hours, days or weeks after the procedure. If unsuccessful you may remain in your current rhythm and your medication would need to be continued or adjusted.
Your recovery
A nurse will monitor your blood pressure, pulse and oxygen levels every half hour for two hours. You will receive oxygen until back on the Unit or are fully awake.
You may experience a slight ‘sunburn’ sensation on the chest wall. If this does occur, an aftersun lotion may be applied to alleviate your symptoms.
When fully recovered, you will be allowed to eat and drink normally and lunch will be provided.
You will receive a further ECG which will be reviewed by the Doctor who will explain your results and discuss your medications.
The procedure is performed under short acting sedation therefore for the first 24 hours you are advised NOT to:
- Drive any vehicle, operate machinery, or undertake work involving danger to yourself or others.
- Use gas or electric appliances.
- Travel home alone.
- Use public transport.
- Be alone in the house.
- Make important decisions or sign important documents.
- Consume alcohol, sleeping drugs or tranquilisers, unless specifically prescribed.
You must have someone responsible to take you home and a responsible adult to stay with you for 24 hours after your procedure.
Discharge
Providing there have been no complications, you will be allowed home and an appointment will be made for you to have an ECG in three months.
You will be given a copy of your discharge letter to keep and one will be sent to your GP electronically.
