Summary
Cardiology documentation is measured, not described. An ejection fraction, a valve gradient, a QT interval, a ventricular dimension, each is a number that must transfer into the record exactly, and each usually arrives from an ECG trace or an echo report rather than from anything said aloud in the room.
That makes the specialty a hard test for ambient scribes, which hear conversation and infer the rest. Research on scribe platforms documents hallucinations that included fabricated test results, which in cardiology is the exact failure that cannot be tolerated even once.
The load the specialty carries is heavy all the same. A letter to the referrer or the GP follows nearly every private clinic, the negative findings need documenting as carefully as the positive ones, and the record has to stand up years later. Here is where a scribe helps a cardiology practice, and where the line sits.
wai drafts the note and the referrer letter from the same consult, with a clinician approving every word. See it on a clinic list.
Book a demoThe numbers problem
A 2025 study that ran simulated encounters through five ambient scribe platforms found roughly 25 percent of key clinical elements omitted or captured erroneously, with omissions making up 76.3 percent of errors, and it documented fabricated test results among the hallucinations. In a specialty where the note carries an ejection fraction, that finding is the whole safety case.
The working discipline has two parts. Speak the findings you want recorded, including the values from the reports in front of you, because a scribe cannot hear a trace. Then read every number in the draft against the source before signing. Our hallucination evidence review sets out the wider research.
Structured results deserve a structured path. The safest systems pull the echo and ECG values from the report rather than from the audio, and keep the conversation for what conversation is good at, the history, the plan and the explanation the patient heard.
The letter is the product
Private cardiology runs on correspondence. The referrer sent the patient, the GP owns the ongoing care, and the letter back is how the clinic's work becomes anyone else's plan. A scribe that ends at the note leaves the letter, which is most of the after clinic typing, exactly where it was.
We have written about what a rejected referral letter costs, and cardiology sits at the sharp end of it. wai drafts the referrer letter from the same consult that produced the note, with the findings, the plan and the follow up in place for the cardiologist to correct and approve. The letter leaves the same day, and a human signs it.
Medico-legal weight
A cardiology record is read most carefully on the worst day, after a missed diagnosis claim or an unexpected death, and what protects the clinician is the documented negative, the chest pain features asked about and absent, the safety netting given, the threshold for return spelled out. Those live in the conversation, which is precisely what an ambient tool captures well.
The draft is never the defence, the signed record is. The clinician remains the author of every word, and our guide to AI scribes and medico-legal risk covers where the liability actually sits. Clinicians still decide what enters the record.
What the evidence says about time
The only randomised trial of ambient scribes, across 238 physicians in 14 specialties, found a 9.5 percent cut in note writing time for one product, about 41 seconds a note, and no significant change for the other, with no reduction in after hours work for either. Both improved how physicians felt about the work.
For cardiology the honest conclusion is that the note was never the bottleneck. The letters, the results chasing and the follow ups are, which is why the time saving question deserves a careful read before any purchase.
The short answer
Trial any candidate on a real clinic and audit every number in every draft against the source reports. A scribe that has never been tested on your echo vocabulary has not been tested.
Then decide what you are actually buying. If the note alone is the problem, the published price scribes are the honest starting point. If the letters, the recalls and the front desk are the real evening, wai covers the consult and the clinic around it at one published price, with a clinician approving everything that enters the record or reaches a patient.
Frequently asked questions
Do AI scribes work for cardiology?
Yes, with a hard rule about numbers. A scribe captures the conversation well, the history, the plan, the safety netting, but measured values arrive from traces and reports it cannot hear. Published research found scribes omitted or erred on roughly 25 percent of key clinical elements and documented fabricated test results among the hallucinations, so every value in a draft is read against its source before signing.
Can an AI scribe write my referrer letters?
A scribe generally cannot, because most end at the note, and the letter to the referrer or GP is most of the after clinic typing in private cardiology. wai drafts the referrer letter from the same consult that produced the note, with findings and plan in place for the cardiologist to correct, approve and send the same day.
Is it safe to let a scribe record ECG and echo findings?
Only through discipline or structure. Either speak the values aloud from the report so the scribe records rather than infers, then read each number back before signing, or use a system that pulls structured results from the report itself and keeps audio for the conversation. Never sign a draft whose numbers you have not checked against the source.
Which AI scribe is best for a private cardiology practice?
Buy for the correspondence and the follow up, not the note alone. The randomised evidence puts the note saving at about 41 seconds, and no scribe reduced after hours work. wai drafts the note and the referrer letter together, codes the consult, and runs enquiries, bookings and recalls through wai Admin at prices published on one page. A note only buyer should start with the published price scribes and audit numbers hard.
