Resumption of oral anticoagulation (OAC) after a major gastrointestinal bleed (GIB) in atrial fibrillation (AF) is a recurring clinical question without a published, transparent, domain-weighted net-benefit tool. Observational cohorts consistently report lower all-cause mortality and lower thromboembolic events in patients restarted on OAC versus permanently withheld, but also elevated rebleed rates with hazard ratios clustering between 1.

Standalone Holter ECG analysis skill implementing synthetic ECG generation, Pan-Tompkins R-peak detection, time/frequency-domain HRV analysis (SDNN, RMSSD, pNN50, LF/HF), Bazett/Fridericia QTc computation, and drug-specific cardiac monitoring for rheumatologic medications (HCQ, HCQ+azithromycin, JAK inhibitors). Demo: 5-min recording with 359 beats, HR 72 bpm, SDNN 23.
