About Dr. Michael Koa-Wing
If you've been told you have an abnormal heart rhythm or you are living with unexplained palpitations, blackouts, breathlessness or chest discomfort; you are in the right place...
I am a Consultant Cardiologist with over 25 years of medical experience, specialising in disorders of the heart's rhythm. I see patients privately in Hertfordshire (Elstree, Bushey and Watford) and London. I hold senior NHS roles as a Clinical Director and Lead Heart Rhythm Consultant at West Hertfordshire Teaching Hospitals NHS Trust and I am part of the world-renowned Arrhythmia Team at Imperial College Healthcare NHS Trust.
My approach is calm, thorough and decisive. I take time to listen carefully, explain your condition clearly, and leave you with a structured plan, so you walk away knowing exactly where you stand and what happens next.
I treat the full range of heart rhythm conditions (arrhythmias), including atrial fibrillation, SVT, recurrent blackouts and more complex arrhythmias, as well as broader concerns such as high blood pressure and chest pain. Where appropriate, I offer catheter ablation and implantable cardiac devices, which include all types of pacemakers, defibrillators and implantable loop recorders all using modern, minimally invasive techniques built for safe, effective and lasting results.
Appointments are typically available within the same week. If you're worried about your heart, I'd be glad to help.

Your privacy matters to me. I handle all personal and medical information with the care and discretion it deserves. I follow all applicable data protection regulations, and your information is used solely for your clinical care. It is never shared without your explicit consent.
A note on consultation notes
I use Heidi, an AI-assisted ambient documentation tool that is NHS-approved and fully compliant with UK data protection regulations. It works quietly in the background during our consultation, helping me capture an accurate clinical record, which means I can give you my full attention rather than writing notes while you speak. I find it genuinely improves the quality of our time together. If you would prefer it not to be used, simply let me know before we begin and I will make alternative arrangements - no explanation needed.
