Have you switched to AI for heart monitoring during physical activity yet?

Hacker News - Fri, 05/15/2026 - 3:15am

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).
