What Makes a Good Electrophysiologist? A Patient’s Guide
I am often introduced to patients as ‘the heart rhythm doctor’, which is accurate but doesn’t explain very much. Most people have never heard the word electrophysiologist before they are referred to one, and I think that is part of why it is so hard for patients to judge who is genuinely well qualified to treat AF. So let me unpick the term properly.
Cardiologist, then electrophysiologist
Every electrophysiologist starts out as a general cardiologist, training broadly across heart attacks, heart failure, valve disease and heart rhythm problems. After that general training, becoming an electrophysiologist means several further years of dedicated subspecialty training focused entirely on the heart’s electrical system, the network of cells that generates and conducts the signal controlling each heartbeat. This includes learning to interpret complex electrical maps of the heart in real time, and to perform catheter ablation, where fine wires are guided through blood vessels to treat the source of an abnormal rhythm directly.
In practice, this means an electrophysiologist has spent years specifically on rhythm problems including AF, atrial flutter, SVT and syncope, in a way that a general cardiologist, however experienced, has not. If you are being considered for AF ablation, this is the specific expertise you want in the room.
| You might see | What it generally means |
|---|---|
| Consultant Cardiologist | Fully trained in general heart disease |
| Consultant Electrophysiologist | Further subspecialty trained specifically in heart rhythm and ablation |
| FRCP | Fellow of the Royal College of Physicians, a UK professional accreditation |
| PhD | Indicates a period of dedicated academic research, often in the specialist’s own field |
| NHS consultant post | Appointed through a formal, competitive NHS process, a useful independent marker of standing |
Training is only part of the picture
Qualifications tell you someone was trained properly. They don’t, on their own, tell you whether that person is still sharp, still up to date, and genuinely good at explaining things to a worried patient at nine in the morning. For that, look at how a specialist communicates during your actual consultation. Do they explain your specific situation in plain language, or do they reach for jargon and move on quickly? Do they draw a picture, or use a diagram, to show you what is actually happening in your heart? Do they answer your questions directly, including the ones that might feel silly?
A retired engineer I treated told me he chose his specialist, in the end, because I was the only doctor who drew him a diagram of his own heart rhythm on paper and let him keep it. He said it was the first time in eighteen months of appointments that he actually understood what was happening to him. 0208 187 9888
What good communication should include
- A clear explanation of what type of AF you have, in plain terms
- An honest discussion of the realistic chances of success with treatment, not just the best case scenario
- Time to ask questions without feeling rushed
- A written or diagrammatic summary you can take away, rather than relying on memory
A good electrophysiologist is someone whose training you can verify, and whose explanations you can actually follow. Both matter. Neither is enough on its own.
