Medicine lost one of its greats this week. My grandpa, Dr. William (Bill) Segar, had an illustrious career that spanned nearly 60 years from @IUMedSchool and @RileyChildrens, @YaleMed, @MayoClinicCV, and @uwsmph and @WiscPediatrics.

Been an exciting journey! Even more excited for what’s next.

We’ve been acquired!

Can standard ECGs flag aortic stenosis years earlier and predict higher mortality post-TAVR? Yes. 🫀 @CardioCareToday highlighted groundbreaking research by Dr. @MattSegar (@Texas_Heart). At AccurKardia, our investigational AK-AVS pipeline is turning the standard ECG into a powerful, predictive biomarker for structural heart disease.

POLY-HF trial: Polypill containing metoprolol, spironolactone, and empagliflozin improved EF, QoL, and adherence, and reduced HF hospitalizations at 6 months in HFrEF patients compared to usual care. #AHA25 View the slides here: clinicaltrialresults.org/wp-…

Never doubted ourselves.

Interesting case with PMCardio - Queen of Hearts. On call today and paged to ED for chest pain. ECG looked completely “benign”. Clinical story suggested an ACS event. We decided to take him to the Cath lab anyways, but used the app to see if I missed anything. QoH noted a STEMI equivalent. Patient ended up having a LCx occlusion. Ended up buying a subscription to the app for that alone. @PowerfulMedical @MartinHerman_ @RobertHermanMD

I experienced my first AI scribe hallucination today. What I said: "Heart rate 71 bpm" What the AI documented: "Electrocardiogram: Normal sinus rhythm" No ECG was performed. The AI scribe extrapolated from basic vital sign data and generated documentation for a procedure that never occurred. Remember, AI scribes are powerful tools, but they're not infallible. They can (and will) "hallucinate" by creating plausible-sounding but completely fictional content. We cannot delegate our professional responsibility to validate documentation. The technology is impressive, but physician oversight remains non-negotiable. Has anyone else experienced this?

AccurKardia launches clinical pilot for AK Guard. Three arm study, 150 patients across care settings. AI hyperkalemia risk from Lead I ECGs, works with FDA cleared wearables. Details: businesswire.com/news/home/2… (Investigational, not FDA cleared.)

First time I've ever seen vibe coding used in the Methods section of a medical conference abstract.

Love the new @JACCJournals style refresh, but the mix of skeuomorphic and flat icon styles sticks out like Comic Sans in a résumé.

Tried @doximity new AI Scribe in clinic yesterday (launched a few days ago). My workflow: record outside patient room during prep, get consent, continue recording throughout encounter. Overall I’m incredibly impressed. I could focus entirely on patient while AI captured everything. As a proceduralist, this is huge for risk-benefit discussions. Instead of frantically documenting while explaining ablation risks, I can engage fully with patient questions. AI captures every detail accurately. Created a cardiology template that structures notes perfectly including dedicated procedural risk/benefit sections. Full experience template: segar.me/blog/posts/doximity…
