Veylino

💚 Veylino is a hands-on rhythm-interpretation trainer built to look and feel like the monitor at the head of an ICU bed. A phosphor-green trace crawls across monitor-black, the grid ticking past in 0.04-second squares, and a countdown runs against you. Read the rate. Read the shape. Commit a diagnosis before the alarm 🚨

🩺 THE BEDSIDE — the drill
Pinch a pair of electronic calipers off their dock and march an interval across the paper. Each leg snaps to the nearest 0.04-second square with a haptic detent — tick, tick, tick — and the readout gives you the span in seconds and the rate it implies. Lock the span and step it forward beat to beat to test regularity. Re-seat the calipers on the PR segment, then the QT. Then call it. Miss, and the monitor is loud about it: 🔴 red alarm, a flatline, and your streak resets. Every call you commit is replayed with its measured intervals and filed away 📋

🫀 THE ARRHYTHMIA ROSTER — the reference
Fifty rhythms across six families — sinus, atrial, junctional, ventricular, AV blocks and paced — each with its own hand-drawn signature trace. Twenty-five carry full depth: diagnostic criteria, rate bands, common causes, management notes and tappable cross-references to the rhythms they are mistaken for. Filter by family or keep a shortlist of favourites 📚

🎓 THE ROUNDS — the curriculum
Fifteen order-gated lessons that build from the ground up: reading the monitor, the 0.04-second grid, marching out with calipers, two ways to count rate, P-QRS-T anatomy, artifact and the impostors, each rhythm family in turn, ectopy in context, the AV blocks, paced rhythms and the rhythms that cannot wait. Lessons hand you straight to the bedside for a knowledge check on the family you just studied 🧠

🗂️ THE STRIP CABINET — the archive
Eight worked example cards to study, plus every strip you commit yourself. Attach a photo of a real printed strip or 12-lead to a card for reference and save any card to your photo library. 📸

🏅 THE COMMENDATIONS — the long game
Twelve hand-drawn medallions for the reads that are genuinely hard: calling a Mobitz I off a lengthening PR, spotting a buried or dissociated P wave, distinguishing flutter by its wave ratio, catching a monomorphic VT or committing a correct call with eight seconds still on the clock. ⏱️

🖥️ THREE MONITOR THEMES
💚 Phosphor green, 🟠 Amber or 🔴 Defib red. Every trace, grid, caliper and medallion is drawn procedurally, so switching theme retints the entire app.
