CardaxEP Boards
Practice electrophysiology with board-style questions, interactive tracings, and worked explanations.
iPhone and iPad

Question bank
Practice EP reasoning with clinical vignettes, rhythm strips, and intracardiac tracings.
- Choose a topic or work through mixed sets.
- Review supraventricular and ventricular rhythms, atrial fibrillation and flutter, pacing and device behavior, and EP study fundamentals.
- Start with a short Quick 10 session or use the Tracing Gym for signal-based questions only.
Interactive tracing explorer
Work directly with synthetic intracardiac electrograms, device strips, and surface ECGs.
- Pinch to zoom and pan across longer tracings.
- Place digital calipers to compare cycle lengths, conduction intervals, or pacing responses.
- Use the expanded view to keep the tracing in front of you while you work through a question.
Tutor and exam modes
Choose whether to learn from each answer as you go or work through a timed set.
- Tutor mode explains the answer after each question.
- Timed exam mode holds the explanations until the session is complete.
- Build a custom session or use a topic-weighted practice exam.
Worked explanations
See why the answer follows from the tracing or clinical scenario.
- Review the key observations and the reasoning behind the correct choice.
- Read why the other options do not fit.
- Use ladder diagrams where included to connect signal timing with the underlying mechanism.
Concept library
Review the concepts behind the questions in a separate reference library.
- Review EP study intervals, entrainment, and para-Hisian pacing.
- Revisit device concepts, channelopathies, and pharmacology.
- Return to a topic between question sessions when you need a refresher.
Progress and spaced review
Use your question history to decide what to study next.
- See performance by topic and identify areas for more practice.
- Revisit missed questions through spaced review.
- Study offline, with progress stored on the device and no study account required.
