Cardiac Codex is RCIS and RCES exam prep for the cardiac cath lab and the EP lab. Study for the Registered Cardiovascular Invasive Specialist (RCIS) exam or the Registered Cardiac Electrophysiology Specialist (RCES) exam with practice questions, timed practice tests, lessons, and flashcards in one app.

Built for cath lab nurses, EP lab nurses, cath lab techs, cardiovascular technologists, and CVIS students preparing for their credential.

WHAT'S INSIDE
• 2,196 RCIS and RCES practice questions with worked explanations
• 4 full-length mock exams at true exam length: 170 questions, timed (2 RCIS, 2 RCES)
• 179 lessons across 97 modules and 15 courses
• 300+ clinical figures: angiograms, hemodynamic waveforms, and 12-lead ECG tracings
• Flashcards covering 1,222 core concepts
• Cardiac Coach — an AI tutor that answers from the curriculum, not the open internet
• Domain-level scoring, so you know which blueprint areas are actually weak

RCIS EXAM PREP FOR THE CATH LAB
Coronary anatomy and angiography, hemodynamics and pressure waveforms, diagnostic cardiac catheterization, PCI and intracoronary imaging, structural interventions and mechanical circulatory support, cath lab pharmacology and sedation, radiation safety, and cath lab emergencies.

RCES EXAM PREP FOR THE EP LAB
Cardiac electrophysiology from the conduction system up: ECG and rhythm interpretation, the diagnostic EP study and pacing protocols, catheter ablation and 3D electroanatomical mapping, and pacemakers, ICDs, and CRT. The EP track alone runs past 40 hours.

BOTH CREDENTIALS, ONE APP
Most prep covers RCIS or RCES. Cardiac Codex covers both.

HOW THE CONTENT IS MADE
Every explanation cites its source. Content is reviewed against current practice, and corrections are logged rather than quietly patched. We publish our review process instead of asking you to take it on faith.
