Everyone with an interest in AI, ECGs, or cardiology should read our paper out in Nature Medicine today! The DRAI MARTINI study tested the performance of DeepRhythmAI from #MEDICALgorithmics for direct-to-physician reporting of ambulatory ECGs. The results overwhelmingly favour the AI, with 14 times fewer missed diagnoses of critical arrhytmias. Read it here: nature.com/articles/s4159… Here's the study in brief: 🏥 >200,000 days of ECGs from >14,000 patients 🩺 >50 experts provided 3-cardiologist beat-to-beat consensus panel annotations of >5,000 ECG events 🖥️ Innovative study design provides absolute rates of missed diagnoses of AF or SVT ≥30s, 3rd degree block, 3.5s asystole or >10s VT Results: 🫀Missed diagnoses in 3.2/1000 patients by DeepRhythm and 44.3/1000 patients by techs 🫀Superior sensitivity (98.6% vs 80.3%) 🫀NPV >99.9% for DeepRhythmAI. This study is the result of an awesome collaboration with true leaders in the field who not only gave their scientific expertise but also committed many hours of their own time doing beat-to-beat annotations of >5,300 ECG events, with consensus annotation on every single beat. This resulted in an impressive author list including @EmmaSvennberg @SZDiederichsen @DrJasonAndrade @WFMMD @AlexanderPBenz @EPjeff17 @PlatonovPyotr @StavrosStavrak1 @Cardiaficionado @Dominik_Linz @JuanBenezet @PhilippKrisai @SanjeevBhavnani @AlirezaOraii @ManningerMartin and many more!

Visionary Voices 2026 Goals | VISIONARY VOICES INCORPORATED donorbox.org/visionary-voic… I have a general skepticism for a lot of charity. Does it really do good? But this project is run by @sanjeevpb and seems just fantastic. Check it out and consider making a small donation

How would you choose to spend 31 million days of ECG? Smartwatches can easily generate this amount of monitoring need - check out our perspective out today: rdcu.be/eSeYc ⚡️Smartwatch sensitivity for AF is unknown ⚡️Downstream effects on healthcare systems are unknown @EmmaSvennberg @SZDiederichsen @WFMMD @EPjeff17 @SanjeevBhavnani @drjohnm

The sun is rising in New Orleans, on the first day of AHA 2025! Tomorrow we show data from the DRAI MARTINI study that answers whether the superior sensitivity of DeepRhythmAI for arrhythmia detection leads to relevant diagnoses or just a mess of incidental findings? Very proud on behalf of the whole study team that this abstract also won the Paul Dudley White Award for Norway. Clinical Science Zone 2, 9.55 in the session "Harnessing AI: Innovations in Arrhythmia Detection and Management". Hope to see you there! @SZDiederichsen @WFMMD @EmmaSvennberg @AlexanderPBenz #Medicalgorithmics #AHA2025

This is an important survey in a rapidly changing field! Please consider taking it!

Great analysis!

Our paper with @StavrosStavrak1 @MToumpourleka and others is now officially published!

The PODCAST trial was presented today at #ESCCongress in Madrid: 🔹 Increasing plasma potassium levels = fewer events of the combined endpoint 🔹 Benefit mainly driven by reduction in ventricular arrhythmias 🔹 Less impact on HF hospitalization or death #CardioTwitter #EPeeps

Really enjoyed this perspective

More good news from Medicalgorithmics! The company just signed a global supply deal with @cardioscanAU – one of the world’s top cardiac diagnostics providers, running 800,000+ tests/year across 11 countries 🌍🫀 (so a big opportunity for MDG, remember- we get paid per test report). Our DeepRhythmAI & DeepRhythm Platform will be powering Cardioscan’s EKG analysis (post-integration & regulatory OK). The algorithms and platform were developed by our amazing #Poland based R&D team and together with help from powerhouse cardiac researcher @lsjMD were recently featured in @Nature (link to study in next tweet below) 🧠 + ❤️ = 🚀 This is our 12th new deal in 2025 – and we’re only halfway through the year. Another major step in making cutting-edge cardiac AI the global standard. nature.com/articles/s4159… #Cardiology #AI #Medtech #Holter #DeepRhythm #electrophysiology #Medicalgorithmics #EKG
