The Slurrred wave in Lead aVL: AI's New Clue to Sudden Cardiac Death 🔍🫀

🫀⚡ Can artificial intelligence discover ECG findings that generations of cardiologists overlooked? This remarkable Nature study trained a deep-learning model on population-scale ECGs and uncovered a previously undescribed biomarker—a subtle slurred terminal R-wave downstroke in lead aVL—that identifies patients at high risk of sudden cardiac death. Most high-risk individuals had preserved left ventricular ejection fraction, highlighting the limitations of current screening. A fascinating example of AI moving beyond prediction to scientific discovery. 🤖🔬❤️
