Day 2 of #HRS2026 - presenting my poster on foundation models to predict cardiomyopathy from 12-lead ECG. Lot of interest in the field for #AI of #ECG 🎉 Thanks to my mentor Dr. @S_NarayanMD and to all my coauthors and collaborators! @ajrogers_md @TinaBaykaner @StanfordMed

#AHA25 was the best! Got to present our work in @S_NarayanMD lab with @ Kelly Brennan, @Sabya_Bando @prash030 using large language models to detect VT recurrence in clinical notes and enable prediction of outcomes, towards precision pharmacotherapy in VT.

Flow Matching (FM) is one of the hottest ideas in generative AI - and it’s everywhere at #ICML2025. But what is it? And why is it so elegant? 🤔 This thread is an animated, intuitive intro into (Variational) Flow Matching - no dense math required. Let's dive in! 🧵👇

Gemini powers our multimodal health research! 💙 In our new paper on multimodal AMIE, we're pushing conversational diagnostic AI beyond text to handle images such as skin photos, ECGs, and clinical docs, which provide crucial context in healthcare. Blog: goo.gle/42D0QcB Paper: gstatic.com/amie/multimodal_… How do we make an AI reason like a clinician during a dynamic, multimodal conversation? One of our key contributions is multimodal state-aware reasoning, built on @GoogleDeepMind Gemini 2.0 Flash. Instead of just reacting turn-by-turn, AMIE maintains an internal "understanding" of the consultation: ✅ What is known about the patient? ✅ What are the likely diagnoses? ✅ What information (text or visual) is missing? This internal state allows AMIE to: 👉 Intelligently guide the conversation through phases like history-taking & diagnosis. 👉 Strategically ask for relevant images (like skin photos or screenshots of ECGs/docs) when its internal state shows uncertainty. 👉 Accurately interpret multimodal data and weave the findings back into the ongoing dialogue and diagnostic process. Essentially, it mimics the adaptive reasoning clinicians use, leading to a more structured and effective consultation. We evaluated multimodal AMIE against primary care physicians (PCPs) in a demanding, blinded OSCE study using 105 diverse multimodal scenarios. The results demonstrate clear progress: AMIE achieved similar or superior performance when compared to PCPs across a wide range of metrics, including diagnostic accuracy, empathy, and critically, the handling and reasoning about multimodal data. While the OSCE results are very promising, it's important to remember this was a test environment with patient actors! Real-world care is more complex. Making sure it's safe, reliable, and actually helpful in the real world needs more work, starting with our upcoming study with Harvard BIDMC. The work would not have been possible without an amazing team @GoogleAI, @GoogleDeepMind: @RyutaroTanno, @alan_karthi, @vivnat, @AdamRodmanMD, @timstro, @taotu831, @hardyshakerman, @JanFreyberg, @_cjpark, @yasharmaa, @apalepu13, @arkitus, @weballergy, @valentinlievin, @ckbjimmy, @davidstutz92, @dgtbarrett, @yongcheng16 @SaraM66905, @dr2w, @ymatias

Great reminders from @S_NarayanMD re: Mapping in the current era - we still have work to do! * EGMs ≠ Action Potentials * How to we compare across #AI models? Very tough to do * with implementation of AI, outcome & workflow need better synchronization #StanfordBiodesign2025

Why do we need #AI in #cardiacEP ? AI models can do tasks beyond humans' capability. Learning features unknown to humans, forecasting, automated remote monitoring, etc. Need more collaborative efforts to bring AI into practice. Great talk by @TinaBaykaner45! @SUBiodesign
