Heart Block / Bradyarrhythmia
Heart block is a delay or interruption of the electrical signals passing from the upper to the lower chambers of the heart, causing a slow heart rate (bradyarrhythmia). It is most common in older people and may follow heart disease.

About heart block / bradyarrhythmia
What to know
Mild first-degree block often causes no symptoms. Higher degrees can cause dizziness, tiredness, breathlessness, fainting or blackouts. Diagnosis is by electrocardiogram, 24-hour or longer rhythm monitoring and sometimes an echocardiogram, with blood tests for causes such as medicines, electrolyte problems, Lyme disease or heart attack. Complete heart block can be life-threatening.
Mild forms are watched, and any slowing drugs are reviewed. Symptomatic second-degree (Mobitz II) or complete heart block is treated with a permanent pacemaker, implanted under local anaesthetic through a small incision below the collarbone. An implantable cardioverter defibrillator (ICD) is added when there is also a risk of dangerous fast rhythms. Pacemaker implantation is routine, and modern devices last many years.
Pre-flight workup
Tests to have already done
- ECG tracings and 24-hour or longer rhythm monitor reports, showing the degree of block and any pauses.
- A clear record of symptoms such as fainting, near-fainting, dizziness, breathlessness or fatigue, with dates.
- Echocardiogram report showing heart pumping function and structure.
- Blood tests including thyroid function and electrolytes, and a list of medicines such as beta-blockers or digoxin that slow conduction.
- Any previous pacemaker details, device card and interrogation report, if a device is already fitted.
Second opinion
When to get a second look
- You have had fainting episodes and been told it is harmless without a monitor showing the heart rhythm.
- A pacemaker is advised for first-degree or mild block without symptoms, which usually only needs observation.
- Your slow heart rate may be caused by a medicine, and no one has reviewed whether it can be changed.
- You need a pacemaker and want to understand whether a single-, dual-chamber or conduction-system device is best.
Talking to your doctor
Questions to ask
- What degree of heart block do I have, and is it dangerous?
- Could a medicine, thyroid problem or reversible cause be responsible?
- Do I need a pacemaker now, and which type?
- What are the risks of the implant procedure?
- What restrictions apply afterwards for driving, exercise and arm movement?
- How often will the device be checked?
Outlook
Realistic prognosis
Mild first-degree block often needs no treatment. For symptomatic or advanced second- or third-degree block, a permanent pacemaker relieves fainting and fatigue and restores a normal lifestyle in the large majority of patients. Outlook depends on the underlying heart condition. Pacemakers last roughly 8 to 15 years before the battery needs replacing, and regular device checks are needed. Complications such as infection or lead movement are uncommon.

Diagnostic workup
Before you pick a hospital, get the workup right
Picking the right treatment is downstream of a complete diagnosis. Skip steps here and the destination surgeon usually re-orders them anyway — at higher cost and another week on the ground.
- Confirm the diagnosis on imaging or labs
For heart block / bradyarrhythmia, plan on the workup your home doctor would order anyway — typically a recent specialist consult plus the imaging / labs the destination team will need to quote accurately. Anything older than 90 days usually gets re-done.
- See a cardiac surgery specialist locally first
An in-person clinical exam at home — even a single consult — costs little and dramatically improves the destination plan. Bring back: written impression, recommended procedure, surgical-risk class, and any contra-indications.
- Send us the file for a free second opinion
Two surgeons in our medical panel review the workup independently. They tell you whether they'd operate, watch, or refer — even if that means recommending against travel.
- Pick a path with timeline + cost in writing
Once a treatment is the right call, we line up 2–3 hospital options with itemized quotes, surgeon profiles, and a travel timeline. You hold the file — switch hospitals or step away at any point.

04 · FAQ
Common questions about heart block / bradyarrhythmia
Do I always need a pacemaker?
No. First-degree block and some mild forms need only monitoring. A pacemaker is advised for symptomatic or advanced block that can cause pauses.
Is pacemaker surgery major?
No. It is a short procedure done under local anaesthetic, usually with a night or less in hospital.
Can I travel and fly with a pacemaker?
Yes. Carry your device card, tell security staff, and avoid lingering near strong magnets. Flying is generally safe once recovered from the implant.
Can heart block be reversible?
Sometimes, if caused by a medicine, thyroid disorder, infection or a high potassium level. Treating the cause may remove the need for a pacemaker.
Clinical context
Working up heart block / bradyarrhythmia properly
A condition like heart block / bradyarrhythmia is rarely well-served by jumping straight to treatment shopping. The sequence below is what a cardiac surgery specialist would expect to see completed — and the absence of any step is the right cue to delay travel decisions.
Diagnostic workup, in sequence
- First-line clinical assessment
History, physical exam, and risk-factor review by a senior generalist or cardiac surgery specialist. Symptoms list, family history, prior workup notes, and current medication list should travel with the patient.
- Standard imaging + labs
Baseline blood work, condition-specific imaging (ultrasound / X-ray / MRI / CT — depending on indication), and ECG / pulmonary function as relevant. Bring digital copies of any prior imaging — saves repeat scans and the cost that goes with them.
- Specialist diagnostic workup
Procedure-specific tests — biopsy, cardiac catheterisation, endoscopy, or genetic / molecular profiling depending on the suspected diagnosis. Done at the centre that will treat, ideally, so results integrate cleanly into the treatment plan.
- Multidisciplinary review (where indicated)
Cancer, complex cardiac, transplant, and rare-disease cases should be reviewed by a multidisciplinary panel — surgical, medical, imaging, and pathology — before any treatment commits. Single-discipline plans for complex disease are a quality red flag.
When to escalate to specialist review
- New, persistent, or worsening symptoms beyond the usual pattern — particularly anything that disrupts work, sleep, or daily function for >2 weeks.
- Symptoms accompanied by red-flag features (unintentional weight loss, night sweats, bleeding, severe pain, neurological signs).
- Any "this feels different" instinct — especially with recurrent or chronic conditions where you know your baseline well.
- A second-opinion misalignment with your current care plan — when two qualified clinicians disagree, the case warrants a third review before committing.
Before you book international travel
- Confirm your specific diagnosis is fully worked up before you commit to a treatment plan abroad. Travelling for the workup is fine; travelling for treatment without the workup done is not.
- Get your case reviewed remotely by the destination centre's team before you book flights — credible international patient programs review imaging + reports before they confirm the surgical plan.
- Bring a digital + physical copy of your full medical record: imaging on USB drive in DICOM format, labs in PDF, current medication list with dosages, allergies, and any prior surgical reports.
- Plan for the post-op rehabilitation phase before you fly — the surgery itself is rarely the bottleneck.
- Confirm that follow-up imaging and any necessary in-person reviews can be done at home — a treatment plan that requires repeat international trips is more burdensome (and more expensive) than the headline procedure.
