LV Mass

What about a little bit of theory before beginning the simulation? >>>

PRACTICE IN THE SIMULATOR

How to perform this examination

1. Run the Echocardiography Online Simulator

Method Area-Lenght:

1. From the List <<Positions>> Choose Parasternal Short PM (Left Parasternal View, Short axis of LV at the level of Papillary Muscles) or find same position with 3D Transducer
2. Click the button <<Freeze>> to freeze image. Using Slider find LV End-Diastolic frame.
3. Click Button <<Calculations>> Click Tab <<LV>> Click Radio Button <<A1>>
4. Click the button <<Curve>> place points around epicardium and Click the button <<Enter>>
5. Click Radio Button <<A2>> Click the button <<Curve>>  place points around endocardium (ignore papillary muscles) and Click the button <<Enter>>
6. Choose 4 chamber position from the List <<Positions>> or find 4 chamber position with 3D Transducer
7. Click the button <<Freeze>> to freeze image. Using Slider find LV End-Diastolic frame.
8. Click Button <<Calculations>> Click Tab <<LV>> Click Radio Button <<L(cm)>>
9. Measure LV long axis.
10. Click the button <<Enter>>
