If you have an implantable cardiac device (ICD) you may have some questions, below are some answers to common questions — check them out to see if yours can be answered.
If you can't find the information you need here, please contact the team using the details at the bottom of the page.
How to use - we currently use four different manufacturers for home monitoring. Please see your manufacturer’s specific information sheet for guidance.
Power cuts - don’t worry. We advise that you check that it powers back up when your power is restored.
Holidays and moving - let us know if you’re going away for more than two weeks and keep it plugged in.
Flashing, beeping or it's not working - firstly switch off and on again. If this hasn't solved your issue, contact customer care helpline relevant to your device.
Concerned that your home monitor isn’t working — if it hasn't been connected with your device for a few weeks, it will notify us. We will then contact you to check the connections and that it's still switched on. If these seem okay, we will ask you to contact the manufacturer who will be able to investigate further.
Don’t panic or worry — your device will still work. Please call your manufacturer who will help guide you through the setup.

The DVLA have strict and complex guidelines on driving once you have an implanted cardiac device and can vary from patient to patient. You can find out more at https://www.gov.uk/browse/driving/disability-health-condition.
If you have a cold, flu, chest infections, or shortness of breath, it's unlikely to be a faulty device. If you are uncomfortable, please speak to your GP first who will be able to assess your condition.
Pacemakers only stop your heart rate going too slow so this should not be causing your heart to race.
If you feel unwell you should seek emergency medical help by calling 111 or 999. If you feel okay, contact your GP.
Sometimes, devices can become infected.
If your device shows any signs of infection such as redness, new bruising, becomes swollen, hot to touch or inflamed, contact the arrhythmia nurses on 01268 394 021 so we can look at the device and assess it.
Your battery may beep or vibrate to tell you that the battery is loosing power. If this happens, contact us as soon as possible so we can arrange for a download of your device.
Sometime some patients feel a twitching sensation in their stomach.
This will not cause you any harm and is probably due to the pacemaker aggravating the phrenic nerve that is near the front of your chest, close to where the pacemaker stimulates your heart.
If you experience this and it's uncomfortable, let us know and we can adjust your device to stop this from happening.
If you can't make an appointment to have your device checked, please contact us to reschedule it.
If you have a pacemaker implanted, most local hospital can check pacemakers. If you would prefer this, let us know and we will contact them to transfer the care of your pacemaker to them. If however, you have an ICD or CRT pacemaker, it may not be possible as some local hospitals do not have the facilities to do so.
Security alarms in the shops are fine. Just walk normally through them, and avoid standing in between for prolonged periods of time.
Airports have thousands of pacemaker and ICD patients pass through them every year and the security staff are trained and familiar with what precautions if any are required of the particular equipment they use.
At the airport, show security your ID card. They should carry out a hand search. Advise them to avoid the use of the wand (detector) and the walkthrough scanners which, in rare cases, can interact with your device.
There are some case reports of electric blankets interacting with some devices. We advise that you don't use it for prolonged periods of time for example when you are sleeping.

Your watch or bracelet will not interact with your device. The heart rates these devices show can be erroneous so try not to get fixated on the number they show as it's often inaccurate.
Some rollercoasters may interact with your device, please follow the ride's precautions.
If you have a Medtronic Reveal ™Loop recorder, you will have been given the activator to use when you have symptoms. If you use this more than once or have symptoms such as passing out of nearly passing out, please contact us and we will arrange for you to come in and have your device checked. If your activator runs out of batteries, you can replace them with Duracell N 1.5V batteries.

Your device is designed and manufactured to protect itself from lots of different operations. Please take your device identification card with you if you attend a pre-assessment.

If you have a pacemaker we won’t have to do anything as we can’t turn them off.
If you have an ICD, we may have to turn it off, especially if you are being cremated. In most cases, it's best practice when reaching end of life to deactivate your ICD in advance. This will not affect the pacemaker function of your ICD and is carried out in the clinic.
