i believe in minimum AI directed cardiac diagnostic tools in arena of big data science. in a sense can electronic chip as big as half of chest if we put on the the L chest provide constructed virtual real time 4D electric/anatomical/functional heart in can safe time, and effort in diagnosis, personalized medicine, and follow up of cardiac diseases with unified AI standards and guidelines? all that only by proper interpretation of thousands of ECG generated from every point in that chip!
