What a device check actually involves
An implantable cardioverter defibrillator (ICD) treats dangerous heart rhythms. A cardiac resynchronisation therapy device with defibrillation (CRT-D) also supports coordinated pumping. The labels are not interchangeable, and a CRT without defibrillation does not deliver shocks. That distinction matters when you describe your device to a new clinician, because the programming, follow-up and alarm settings differ.
A device check is not a single test. It typically combines a programmer interrogation, a review of stored arrhythmia episodes and lead measurements, a battery and impedance assessment, and a clinical review of symptoms, medicines and any recent shocks. Some checks are routine; others are prompted by a specific event such as a shock, dizziness, breathlessness or a change in medication. The receiving electrophysiology team decides which elements are needed for your situation.
Before you travel, ask your current device clinic for a recent interrogation report, the device make and model, the implant date, the lead types, the programmed parameters and the last battery estimate. These are the documents a new team will want to see. If any are missing, ask what can be released and whether a summary letter is enough to start.
Decisions to settle before you book flights
The order of decisions matters more than the itinerary. First, confirm with your current cardiologist or device clinic whether travel is appropriate given your recent rhythm history, battery status and any pending programming changes. Second, confirm with the receiving team in China whether they will accept you for a device check, and under what conditions. Third, confirm what documentation they need before they will schedule. Only then should you commit to flights and accommodation.
Ask the receiving team directly: will they interrogate my specific device model, and do they have the corresponding programmer and leads? Device manufacturers use different programmers, and not every clinic stocks every system. This is a question to confirm, not an assumption. If the answer is uncertain, ask whether an alternative hospital or a manufacturer representative can support the check.
Ask whether the check is a one-off review or part of a longer follow-up plan. If you are travelling for a separate procedure, the device check may need to happen before, after or alongside it. Ask who coordinates that sequence, and whether the device team and the treating team will communicate directly.
Ask what happens if the device needs reprogramming, a lead revision or a generator change during your trip. Availability of specific device models, leads and accessories varies by hospital and by current stock. Ask the named provider what they can confirm for your device and dates, rather than assuming a replacement will be on hand.
Remote monitoring and travel: what to confirm
Many modern ICDs and CRT devices support remote monitoring, but compatibility is not universal. The system depends on the device manufacturer, the transmitter or app, the clinic's enrolment and the country where the monitoring is hosted. Do not assume your home remote-monitoring setup will continue to work in China, or that a Chinese clinic can take over your existing remote account.
Ask your current device clinic what they recommend for the travel period. Some clinics ask patients to keep the home transmitter connected at a fixed address; others arrange a temporary pause or a different follow-up interval. Ask whether the receiving team in China can review remote transmissions, and if so, under what arrangement. If remote monitoring cannot be continued, ask what in-person checks are needed instead.
If you use a smartphone app or a bedside transmitter, check whether it will work on the local network and whether the manufacturer's server accepts transmissions from China. This is a technical question for the device manufacturer and the receiving clinic, not something to resolve at the airport.
Keep a written record of your device details, the last interrogation, your current medicines and your allergy history in your hand luggage. If you become unwell during the trip, this record helps any clinician who sees you.
MRI, airport security and other practical questions
MRI access with an ICD or CRT depends on the specific device, the leads, the implant date and the hospital's protocols. Not every device is MRI-conditional, and even conditional devices require specific programming before and after the scan. If you might need an MRI in China, ask the receiving radiology and device teams to confirm in advance whether your exact system can be scanned and who will reprogram it.
Airport security screening is generally manageable with an ICD or CRT, but the process varies. Ask your device clinic for a device identification card, and be prepared to show it. Security staff may use a hand search instead of a walk-through metal detector. Follow the instructions given at the airport and by your device team.
Other practical questions worth settling early include: who will see you if you have a shock during the trip; which hospital to attend; how to reach the device team out of hours; and whether you need a companion who knows your device history. These are contingency plans, not predictions.
Records and questions that change the next step
The records that most change the receiving team's answer are the recent interrogation report, the device and lead identification, the implant date, the current programmed settings, the last battery and impedance measurements, and a summary of any recent arrhythmias or shocks. A medication list and a recent clinical letter are also useful.
Ask your current clinic to provide these in English where possible, or with a translation. If a full record is not available, ask what summary would be sufficient to start a review. Missing documents do not necessarily prevent an initial conversation, but they may limit what the receiving team can confirm.
Prepare a short list of questions for the receiving team: Can you interrogate my device model? Do you have the programmer and leads? Will you review remote transmissions? What is the plan if the battery or a lead needs attention during my trip? Who do I contact if I have a shock? What written instructions will I receive before I travel?
The answers to these questions determine whether you book a device check only, combine it with another appointment, or delay travel until a specific issue is resolved. They also determine whether you need a companion, a longer stay or a contingency hospital.
Next steps for planning a device check
ChinaSpecialistCare provides non-clinical coordination for international patients. For a device check, that can include helping you identify a hospital with a cardiology or electrophysiology service, requesting an appointment, and preparing the records the receiving team asks for. We do not diagnose, programme devices or decide suitability; those decisions belong to the treating hospital and licensed clinicians.
If you would like to start, send a short summary of your situation through the enquiry form, email or WhatsApp. Include your device type, the reason for travel and your main question. An initial enquiry is free and does not require buying a proxy consultation. After first contact, we can explain how to share records securely and what the next step looks like.
