Electrophysiology (EP) study
Mapping the heart's electrical pathways to pinpoint the source of an arrhythmia.
Specialist service
Heart rhythm care
Steady the beat. Restore the rhythm.
Whether it's a fluttering atrial fibrillation, slow heartbeats or unexplained fainting, our electrophysiology service finds the source and fixes it. We use 3D electroanatomic mapping and cryo- or radiofrequency ablation for the highest success rates with the lowest possible risk.

Who this is for
You'll benefit if…
- Atrial fibrillation, flutter or supraventricular tachycardia
- Frequent palpitations or skipped beats
- Unexplained dizziness, fainting or near-fainting
- Bradycardia (slow heart rate) needing a pacemaker
- Existing device patients needing programming or upgrades
Conditions we treat
Common reasons patients are referred
- Atrial fibrillation and flutter
- Supraventricular tachycardia
- Ventricular ectopy and tachycardia
- Bradyarrhythmias requiring pacing
- Unexplained syncope
- Inherited arrhythmia syndromes
What we offer
Procedures and assessments
A focused, high-volume set of procedures — performed often and performed well, by the same senior team every time.
Catheter ablation
Targeted cryo- or radiofrequency energy to silence misbehaving tissue — often a one-time cure.
Pacemaker implantation
Single, dual or biventricular pacemakers for slow rhythms and heart failure.
ICD & loop recorder implants
Defibrillators and tiny under-skin monitors for high-risk and unexplained-symptom patients.
Device follow-up & remote monitoring
Quarterly checks and 24/7 home transmissions keep your device tuned and your data flowing to us.
Technology
The tools we use, by name
The equipment behind this specific service — chosen because precise tools support precise decisions.
- CARTO 3 electroanatomic mapping
Millimetre-precision 3D mapping for safer, more durable ablations.
- Medtronic Arctic Front cryoballoon
One-shot pulmonary vein isolation for atrial fibrillation.
- Biosense Webster radiofrequency catheters
Contact-force-sensing tips for consistent, predictable lesions.
- Medtronic & Abbott CRM devices
Full range of pacemakers, ICDs, CRT-D and Reveal LINQ loop recorders.
Your journey
From first call to follow-through
1
Rhythm assessment
ECG, Holter and often a wearable patch monitor to capture the offending beats.
2
Treatment plan
Medication, lifestyle changes or procedure — chosen with you, not for you.
3
Follow-through
Regular device interrogation and rhythm checks for as long as you need them.
How to prepare
- Stop antiarrhythmic drugs as instructed — usually 5 half-lives before the EP study.
- Fast from midnight if the procedure is in the morning.
- Bring all rhythm strips, Holter reports and previous device interrogations.
- Plan one night in hospital and a driver for the next day.
- Wear loose, button-front clothing for easy access to the chest after a device implant.
Recovery & aftercare
- Rhythm diary
Simple daily log app linked to your cardiologist for the first 90 days.
- Remote device check
Bedside transmitter sends data nightly — no extra visits needed.
- Anticoagulation review
Stroke-risk score recalculated at every visit; bleeding risk reviewed in parallel.
"Three years of palpitations gone in a single afternoon. I keep waiting for them to come back — and they don't."

FAQs
Questions patients ask us
If yours isn't here, ask our team — we love a good question.
Is ablation painful?+
It is done under sedation or general anesthesia — you will not feel the procedure.
Can I keep my phone near a pacemaker?+
Yes, modern devices are well-shielded. We give you a simple do/don't list at discharge.
Do I have to take blood thinners forever?+
Not always — it depends on your stroke-risk score, which we recalculate at every visit.
Why CAVA
Care that is precise — and personal
The same standards apply to every service we offer.
- Board-certified specialists
Every study is read and every procedure performed by a fellowship-trained cardiologist or vascular surgeon — never an outsourced reader.
- Same-day diagnostics
ECG, echo and duplex ultrasound on-site, with results explained in plain language before you leave the clinic.
- Minimally invasive first
We default to wrist access, local anaesthesia and outpatient pathways — so most patients are home the same day.
- Continuity of care
One named cardiologist follows you from first visit through recovery. No revolving door, no repeated histories.
Safety
- Joint Commission International (JCI) aligned protocols
- ESC, AHA and ACC guideline-based care pathways
- Time-out checklists before every procedure
- Closed-loop medication reconciliation at every visit
Accreditations
- European Society of Cardiology — affiliated practice
- American College of Cardiology — institutional member
- Society for Cardiovascular Angiography & Interventions
- Vietnam National Heart Association — accredited training site
Fees & insurance
- Direct billing arrangements with most major local and international insurers.
- Transparent published fee schedule — written estimate before any procedure.
- Interest-free payment plans available for elective procedures.
- Dedicated insurance liaison who handles pre-authorisation on your behalf.
