Comparing the Conductance Catheter with Sonomicrometry

Note: The following information pertains to equipment used in animal-based cardiac research. If your interest is in clinical devices used on human patients, please click here for more information.

Sonometrics manufactures advanced sonomicrometry devices which have a well established reputation for accurate and validated measurement of cardiac volume and regional function (clinically known as "wall motion"). Items such as stroke volume, cardiac output, ejection fraction, wall thickness, segment length, chamber dimensions and cardiac size are all derived from the measurements made by our instrumentation. Our software carries that one step further by calculating stroke work, PRSW, E-Max (also known as ESPVR or compliance) and many other calculations.

The purpose of the information presented here is to compare sonomicrometry with conductance catheters because they are the two most common methods for the measurement of cardiac volume in research labs.
