EKG practice strips

Read a lead II rhythm strip and name the rhythm. Every strip is drawn by the same generator as the simulator's cardiac monitor.

Treat the patient, not the monitor

A strip is one lead on one patient at one moment. Check a pulse and look at the person before acting on any rhythm, and confirm a flat line in a second lead.

What is this rhythm?

Source

The strips are drawn by this product's ECG generator, the one the simulator's cardiac monitor uses. The identifying criteria follow standard basic-arrhythmia teaching, as in the American Heart Association's ACLS Provider Manual and Garcia TB, Miller GT, Arrhythmia Recognition: The Art of Interpretation (Jones & Bartlett).

A generated strip is clean in a way a real one rarely is: no artifact, no wandering baseline, one lead. Recognizing a pattern here is a start, not a substitute for reading real tracings with an instructor.

Knowing the number is not the same as running the call.

60-second call

One patient. Four vitals. Your priority actions. Every case is written at Paramedic (ALS) scope.

A short prehospital call with four vitals, from a real-life scenario a paramedic wrote. Type your priority actions and why, and get a debrief graded against a paramedic's rubric. Cases are written and graded at US Paramedic (ALS) scope.

Full scenarios

Run the whole call, dispatch to handoff.

Every one of the 207 calls in the library is written by a paramedic and runs at EMT or Paramedic scope. You work the call in your own words, and the debrief shows you what you missed and why it mattered.
