Cardiac Measurements
The following table shows tha cardiac measurements available 
on the LOGIQ 3 Expert/LOGIQ 3 Pro/LOGIQ 3
When you make a measurement,you select the abbreviationfor 
the measurement on the Touch Panel. Most abbreviations are 
made using acronyms. The following table lists acronyms used 
for naming cardiac measurements.
