Immediately, a bedside echo was done. Here is the video:
This shows a huge and poorly functional RV.
Here is a still picture from the video:
|The RV is on the left, the LV on the right (thick-walled). The RV is very enlarged and looks like a "D". Accordingly, this is called the "D" sign.|
This is diagnostic for pulmonary embolism, which was subsequently proven. Thrombolytic therapy might have been given, but at least partly because of head trauma from syncope, it was not.
