ECG Rhythm Lab

Medical Readiness

A live simulated patient monitor. Watch the ECG, pulse oximetry, and capnography sweep together in real time, pick from the rhythm library and learn how to read it, or turn on quiz mode and identify rhythms until it is reflex. Over 55 percent of Calgary Fire's 92,200 calls in 2025 were critical medical, and Heart and Stroke estimates about 60,000 out-of-hospital cardiac arrests happen in Canada every year, roughly one every nine minutes, with only about one in ten surviving. Rhythm recognition is fireground work now, and it is the core skill of every EMR, PCP, and ACP course.

Vendor neutral on purpose: we train ECGs and medical assessment, not devices. What you learn here reads the same on whatever monitor or AED your service runs.
