- Printed rhythm sheets
- Limited practice tracings
EKG/ECG Technician (CET)
Interpret rhythms with AI-speed feedback.
Marcus AI trains you to perform electrocardiograms, recognize arrhythmias, and prep for national CET exams without second guessing.
What it is
The Certified EKG Technician credential offered by organizations like the NHA proves you can prep patients, capture clean tracings, and flag urgent rhythms. Hospitals, cardiology practices, and mobile diagnostics depend on CETs to keep cardiac pipelines moving.
Marcus AI combines rhythm strip simulations with quick-recall drills so you master conduction pathways and lead placement faster than lecture-only prep.
Why it matters
Quality tracings reduce repeat tests and delays in cardiac treatment.
Marcus AI spots where you misread strips and immediately regenerates similar rhythms until recognition is automatic.
CET certification stacks well with phlebotomy or medical assisting, broadening your scope and earning potential.
Salary & job outlook
Cardiovascular technologist roles, including EKG technicians, show steady growth with demand highest in hospital telemetry units and mobile diagnostics (source: BLS).
Eligibility
- High school diploma or GED
- Completion of EKG training program or documented clinical experience
- Current CPR/BLS certification

The Marcus AI approach
With Marcus AI you enter an adaptive preparation pathway grounded in learning science. We combine Single Learning Units (SLUs), adaptive sequencing, and evidence-based techniques so you master every exam domain without slogging through outdated textbooks.
- SLUs: Master one concept at a time—whether it’s airway management, leadership frameworks, or networking fundamentals.
- Adaptive sequencing: Embedded diagnostics skip what you already know and drill the exact gaps holding you back.
- Evidence-based methods: Retrieval practice, spaced repetition, interleaving, and adaptive testing make every study block count.
- Record-time results: Learners routinely finish 60–90% faster than with traditional courses.
- Exam-ready drills: Full-length mocks, scenario simulations, and readiness scoring ensure you walk into test day confident.
Choose Marcus AI and prepare smarter, not longer—so you arrive at the exam confident, competent, and ahead of the pack.
