LVOT VTI and stroke volume, RVSP, diastolic function by the 2025 ASE algorithm, tamponade inflow variation and TAPSE. Every waveform is generated live and timed to the ECG.
Trace the LVOT VTI, calculate stroke volume and cardiac output, and judge fluid responsiveness after a passive leg raise.
Measure peak TR velocity on CW Doppler and estimate right atrial pressure from the IVC.
Measure E, A, septal and lateral e′, E/e′ and TR, then grade with the 2025 ASE algorithm, step by step.
Measure respiratory variation of mitral and tricuspid inflow on a slow sweep with a respirometer trace.
Measure tricuspid annular excursion on M-mode with calipers.
Change any value and watch the waveforms respond, test yourself on random cases with a full answer key, and look up every wave and cutoff with references.
After you measure a case, the trainer marks each value, shows the math and walks through the guideline step that decides the answer.
Here the E/e′ was miscalculated, but the final grade was still right.
Peak of the early wave on mitral inflow.
98 / 5.5, using (septal 5 + lateral 6) / 2.
You entered 12.
Peak of the CW envelope.
All three are abnormal: elevated LAP. E/A 1.4 is under 2, so grade 2.
Checkout gives you a license key and a button that unlocks the trainer in that browser. The key is also in your receipt email, so you can unlock up to 3 browsers or devices.
No. Every waveform is generated by software from published definitions and timed to a synthetic ECG.
No. It is an educational simulator. Use your own training, your institution's protocols and the full clinical picture for patient care.
Diastolic grading follows the 2025 ASE update. RVSP, RAP and TAPSE follow the ASE right heart guidelines. Stroke volume and tamponade cutoffs are cited to the studies and ASE recommendations listed in the guide.
Yes. It runs in any modern browser on phone, tablet and desktop.
