Open with ECG, then keep expanding.
Work through rhythm recognition in focused rounds while the foundation is fresh.
Study challenge pass
Small challenges.Big futures.
Pass the Scrub turns medical-assistant studying into quick, interactive challenges. Start with ECG practice, build your recall, and walk into class ready to think.

ECG: Rhythm basics
Challenge 03 of 08
Optional timer
Rhythm stripLead II
Identify the rhythm pattern before you check the explanation.
Which rhythm is most consistent with regular P waves followed by narrow QRS complexes?
AAtrial fibrillation
BNormal sinus rhythm
CSinus bradycardia
DPremature ventricular contraction
Why it fits: Normal sinus rhythm has organized atrial activity and a regular ventricular response.
Practice builds confidence
Quick sessions that fit real life
Plain language after every choice
Practice with a purpose
Built for better recall
Study less like a spectator.
Every challenge is designed to make the next study block more useful—not just longer.
Know what needs a repeat.
Track topic progress, mark completed rounds, and return to missed concepts for another pass.
Make the daily challenge count.
A simple daily challenge and streak view help study momentum become a habit.
The learning loop
Challenge. Understand. Return stronger.
- 01 / Challenge
Answer before the reveal.
Choose your pace: untimed for thoughtful review, or turn on a timer when you want the pressure.
- 02 / Understand
Get the why, not just a score.
Every answer choice gets a plain-language explanation so you can connect the decision to the concept.
- 03 / Return
Review what you missed.
Your progress and review tools point you toward the concepts worth seeing again—without starting from zero.
Coming into focus
A clearer way to support a whole class.
Instructor-ready class tools are on the road ahead: assignments, due dates, results, and a view of the concepts the room needs to revisit.
Built for learners now. Ready for classrooms next.
