Yes. Taking a cruise is safe with an ICD. The ship’s radar equipment is located well away from passenger areas and is very unlikely to interfere with your device.
Before travelling, make sure you carry your device ID card at all times, as it contains important information about your device and may be needed at port security. It is also worth contacting your travel insurer to confirm your cover — see our FAQ on travel insurance for more information. Let your device clinic know you are travelling so they can advise on remote monitoring arrangements if needed.
