- For
- Echocardiography learners and clinicians reviewing cardiac imaging
- Worth noticing
- A view selector connects probe position, a labeled cardiac cross-section and its matching echo image; Doppler examples show velocity, the Nyquist limit and aliasing.
Field notes
The examples connect measurements to visible anatomy: the IVC section places a caliper 1 to 2 cm from the right atrium and shows its change during quiet breathing and a sniff. A Wiggers diagram brings pressure, volume, ECG, heart sounds and Doppler traces into one heartbeat timeline. The page also contrasts normal coronary anatomy with buttons for LAD, RCA and circumflex occlusion.
