What happens after the device has been implanted?
After the implant you will be required to stay in the hospital for 1-2 nights. This is so you can be monitored and the device can be checked to ensure that it is functioning properly.
You will notice some bruising, swelling and tenderness around the insertion site. This is because the implanting doctor had to make some room under your skin for the device to fit into. These symptoms will resolve in a couple of weeks following the implantation procedure. The site itself will be stitched together to help the healing process. The stitches used are dissolvable and should dissolve within one month following the implant. Until the site has healed you should not play vigorous sports such as tennis, golf or swimming. It is important however that you start moving your shoulder gently from the day after your implant. This will keep your arm and shoulder flexible.
You will be sent an ICD identification card 6-8weeks after your ICD implantation. This card is very important and should be kept with you at all times. It has information about your device and who should be contacted about the device in the event of an emergency.
Follow up – How do I know my device is working properly?
You will be required to have your wound and device checked 4-6weeks after the implant at either the RMH defibrillator clinic or with the cardiologist who implanted the device. At this appointment your wound will be checked to ensure it is clean and healthy and is healing properly. The ICD will also be checked. The doctor or a Cardiac Technologist will perform this testing using a computer that has been made especially to communicate with your ICD. This is a non-invasive test to check the battery and leads of the device and how it is interacting with your heart. Information about any arrhythmias you may have had since the implant will be obtained during testing. The ICD program may also be altered at this appointment if necessary.
You must have your device checked regularly to ensure it is working appropriately.
These appointments will occur every 1-6 months at the discretion of your cardiologist.
It is important to bring a list of your medications and the doses you are taking.
How will the device affect my daily activities?
You should remember that this device has been implanted to ensure you can keep on living a normal, active life. There are a few activities that you will be unable to perform however most of your life will continue just as it had before the ICD was implanted. It is important to follow the advice your cardiologist has given you in relation to returning to certain activities.
Medications – The ICD is implanted to terminate abnormal rhythms. It can not prevent these abnormal rhythms from starting. Your cardiologist will have prescribed specific medications to try to prevent these arrhythmias from starting. It is very important to take all of the medications your cardiologist has prescribed. Any changes to your medications should be made in consultation with your cardiologist.
Driving – You should discuss with your cardiologist as to when you can resume driving and you should not recommence driving until you have been advised to do so by your cardiologist. In general, transport regulations do not permit commercial driving (taxi, bus, truck etc) after ICD implantation.
Working – The length of time you will be required to stay off work will vary on an individual basis, depending mainly upon the type of work you do. You may be able to return to light duties as early as two weeks after the implant. Your cardiologist will discuss with you how long until you may return to work.
Exercising and Sexual Activity – Current ICDs are able to distinguish between normal heart rate increases caused by exercise, activity or intimacy and those caused by an abnormal heart rhythm. You should not receive any shocks for normal increases in heart rate.
You should begin gentle arm and shoulder movements as early as possible after the implant. This may cause some discomfort, however it will help to keep this area flexible. Sports such as tennis, golf, boating, swimming and fishing should not be played until your wound has healed, usually about one month post implant. If you participate in hunting or shooting sports, the rifle should be rested on the opposite shoulder to that of your device.
Most patients are able to resume normal sexual activities when the wound has healed. If you receive a shock during intercourse your partner may feel a tingle or your muscle spasm however they should not be harmed.
Travelling – You must remember to take your ICD identification card when you travel. This provides information to any medical or security staff that you may encounter in your travels. The walk-through security gates at airports may detect the metal of your device and sound an alarm. . You can show your ID card and ask for a hand search. The security gates should not affect the functioning of the device, however it is recommended that you walk briskly through these gates. The hand-held security wands may temporarily interfere with the function of the device. Always show security staff your ID card and ask for them not to hover over your ICD with these hand-held devices. Alternatively you may ask for a hand search.
Medical Procedures – It is very important that your doctors (and dentists) are aware of your ICD before any procedure. Sometimes your device may need to be reprogrammed, or you may be required to take antibiotics.
Emotions – You are likely to experience many different emotions as a result of your condition and the implantation of an ICD. Feelings of depression, anxiety, anger and fear are common but may be eased by learning about your condition and your device, preparing for emergencies and by talking to your family, ICD clinic staff and your doctors about your concerns.
What can’t I do?
For the safety of yourself and those around you, there are some restrictions to your activities. ICDs use electrical signals to detect your heart rhythm. There are external sources of electromagnetic signals that may interfere with your device and are safest to avoid. Equipment and situations that may cause a problem with your ICD include: electric welding, industrial equipment, poorly grounded electrical appliances, lithotripsy, therapeutic ultrasound and electrosurgical instruments. Mobile and portable telephones should be used with caution. It is recommended that you use the ear on the opposite side to your device and do not carry the phone in your breast pocket above the ICD.
You must not, under any circumstances, have an MRI scan.
How long does the battery last?
Batteries in these devices typically last for 4-6 years however this is dependent on the amount that the device is used. The more the device is used, the shorter the life of its battery. When the battery does run down, an ICD replacement procedure will be organised for you. This procedure is similar to the implant although in most cases the original leads are left in position and connected to the new device.
The battery status is monitored every time you come to get your ICD checked.
How can my family help?
Your family and friends are able to help you adjust to your ICD in many ways. As your driving abilities have been restricted it is helpful to have someone to drive you or organise transport when necessary. Those you live, work or socialise closely with should know how to respond if you do develop an arrhythmia or get a shock
What support is available?
The Royal Melbourne Hospital Department is developing an ongoing education and discussion session. This will be run every 6 months and will provide a forum for you to learn about your ICD and to meet others with these devices. You will be able to share your experiences and learn from those who have been through the procedure before you. Information about these sessions will be sent to patients with an ICD.
