What is in the trainer

Stroke volume

Trace the LVOT VTI, calculate stroke volume and cardiac output, and judge fluid responsiveness after a passive leg raise.

RVSP

Measure peak TR velocity on CW Doppler and estimate right atrial pressure from the IVC.

Diastolic function

Measure E, A, septal and lateral e′, E/e′ and TR, then grade with the 2025 ASE algorithm, step by step.

Tamponade

Measure respiratory variation of mitral and tricuspid inflow on a slow sweep with a respirometer trace.

TAPSE

Measure tricuspid annular excursion on M-mode with calipers.

A sample answer key

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.

Answer key
Correct
Mitral E: 98 cm/s

Peak of the early wave on mitral inflow.

Missed
Average E/e′: 17.8

98 / 5.5, using (septal 5 + lateral 6) / 2.

You entered 12.

Correct
Peak TR velocity: 3.10 m/s

Peak of the CW envelope.

Correct
Diastolic function: Grade 2

All three are abnormal: elevated LAP. E/A 1.4 is under 2, so grade 2.

Questions

How do I get access after I buy?

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.

Are these real patient images?

No. Every waveform is generated by software from published definitions and timed to a synthetic ECG.

Can I use this to interpret my patient's study?

No. It is an educational simulator. Use your own training, your institution's protocols and the full clinical picture for patient care.

Which guidelines does it follow?

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.

Does it work on my phone?

Yes. It runs in any modern browser on phone, tablet and desktop.

Can my program buy it for a group?

Yes. Email [email protected] for group licenses.

What if it is not useful to me?

Email within 14 days of purchase for a full refund. See the refund policy.
