Electrode placement
Practice placing ten electrodes on the virtual patient with visual feedback. Configure paper speed and gain.
ECG, one beat at a time.
From electrodes to interpretation: explore a virtual patient, follow a moving tracing and connect each change to cardiac physiology.
Explore. Observe. Understand.
Turn concepts from your lessons into visual experiences.
12 moving leads
Observe the same patient from different perspectives. Adjust heart rate, pause the recording and compare wave morphology.
Axis and electrolytes
Explore the electrical axis and combine potassium and calcium changes with a baseline tracing comparison.
Pathologies and a 3D heart
Explore arrhythmias, blocks and coronary scenarios. Observe the relationship between the heart, affected territory and leads.
Step-by-step lessons
Start with electrical activity and build toward interpretation. Open deeper explanations, experiment in the simulator and track your progress.
Progressive quizzes
Answer questions about the simulator, get immediate feedback and discover which lessons to review.

Before you start
Do I need to install software?
No. The simulator runs in your browser with a separate MedSimulator account.
Can I use it on my phone?
Yes. The interface adapts to phones and tablets; a larger screen makes comparing all 12 leads easier.
Is it intended for clinical care?
No. This is an educational tool. Scenarios are learning models and do not replace clinical assessment.
