📏 Finally, a ruler that actually helps me read ECGs without panicking.
Okay, medblr. You know that moment when you're staring at a 12-lead ECG and trying to remember if that QT interval is too long? Yeah. This little tool solves that.
Meet the Portable ECG 7-Step Ruler – and yes, it fits in your pocket.
What it does:
Measures heart rate (30-300 bpm scale)
PR interval, QRS duration, QT interval
7-step interpretation guide printed right on it – no flipping through textbooks
Why I like it: 🧠 No batteries, no apps, no Wi-Fi 🧼 Wipe-clean (because hospital things are gross) 👂 Fits in a badge holder or scrub pocket 💸 Cheap enough that losing one won't ruin your day
Who needs this: Med students on rotation Nursing students Paramedics / EMTs Cardio techs
Anyone who has an ECG exam coming up tbh
🎥 Watch the video above to see how it works – quick demo, no fluff.
