Here's how AI can monitor your heart during physical activity AI (ACCO AI watch): your myocardium is lacking oxygen (HOV — myocardial oxygen consumption, CMBV — coronary blood flow volume); the heart beats but pumps blood inefficiently (EWK — left ventricular efficiency, CPO — cardiac power output); one of the ventricles is overloaded (LVSW — left ventricular stroke work, RVSW — right ventricular stroke work); the risk of thrombosis is increasing due to thick blood (FIB — fibrinogen activity surrogate); you are on the verge of dehydration, and the heart fills with blood worse than it should (CVP — central venous pressure, GEDV — global end-diastolic volume). Six risks. Standard fitness trackers see none of them.

Measurements are taken every 5 minutes. Based on that data, the watch generates real-time alerts with three parts: Implication (what's happening to your heart right now), Evaluation (green/yellow/red zone), and Suggestion (slow down, drink water, stop, or change exercise type).

This sounds interesting, but I’d be curious about the clinical validation behind these metrics. Predicting things like thrombosis risk from a wearable is a pretty strong claim.
