What is Cardiac Rhythm Simulator?
Cardiac Rhythm Simulator is a browser-based ECG training tool for medical and nursing students, educators, and early-career clinicians. It generates simulated heart rhythms, plays back more than 45,000 real clinical recordings from public research datasets, and tests rhythm recognition through quizzes.
It is built for learning, review, and teaching — not for diagnosis or patient care decisions.

Common questions about the ECG simulator
Quick answers about practice use, data sources, teaching workflows, and limitations.
Is this useful for ECG Rhythm Interpretation Certificate preparation?
Yes. The simulator, rhythm quiz, and real-case explorer are designed to support ECG review, rhythm recognition, and ECG Rhythm Interpretation Certificate exam preparation. It works best alongside formal instruction and course materials.
Are the rhythms real or simulated?
Both. You can explore a library of real clinical recordings and also generate or edit synthetic rhythms for teaching and practice.
Can instructors create custom teaching scenarios?
Yes. Signed-in users can build custom rhythms, save them to a personal library, and load them into the simulator for repeatable demonstrations.
Is this intended for diagnosis?
No. Cardiac Rhythm Simulator is an educational tool for learning, review, and teaching. It should not be used as a substitute for clinical judgment or patient care decisions.
