Why now

Cardiovascular devices are among the largest groups on the FDA's AI-Enabled Medical Device List, second only to radiology.

Randomized trials now show that ambient AI scribes save documentation time and reduce burnout, and the EAGLE trial showed that AI-ECG increases new low-EF diagnoses.

The rule for all of them is the same: AI drafts, the physician verifies.

AI inside the EHR

Most cardiologists already have generative AI inside the EHR: Epic reports that 85% of its customers are live with its built-in tools, which run on models hosted on Microsoft Azure.

Communication and compassion

In a JAMA Internal Medicine study, blinded raters found chatbot drafts more empathetic than rushed physician replies.

In real in-baskets, AI-drafted replies reduced task load and exhaustion but did not save time.

Patients accept AI drafts when a physician reviews each one and AI use is disclosed, and they prefer serious news by phone or in person.

LLMs also turn echo and CT reports into plain-language summaries and first-draft translations, which a qualified interpreter should check.

Governance

The AHA science advisory calls for local validation, bias testing, and ongoing monitoring before and after any AI tool goes live.

Case scenario (fictional)

A 72-year-old man with bilateral carpal tunnel syndrome is referred after an ECG-AI amyloidosis flag.

An ambient scribe drafts the note, and the cardiologist corrects a furosemide dose before signing.

AI-assisted echo shows 15 mm walls with apical-sparing strain, so PYP scintigraphy and free light chains are ordered with an AI-drafted prior-authorization letter.

A plain-language summary in Nepali, checked by bilingual staff, goes to his daughter, while the possible diagnosis is discussed by phone.

Bottom line

AI now touches every cardiology modality, and the cardiologist's job is to pick validated tools, verify every output, and spend the saved time with patients.
