The MPVS-Ultra Foundation System is configured for measurement of left ventricular pressure (LVP) and volume in small (rat or mouse) through to large animal (sheep, pig) hearts, using the appropriate pressure-volume (PV) catheter. A variety of PV catheters are available for particular species with all catheters having pressure sensors (single or double) and multiple electrodes (see below). Due to their small size the sensors can be directly placed into the left ventricle of the heart for simultaneous measurement of pressure and volume with minimal disruption to heart function. In vivo, the catheters can be used in either closed or open-chest preparations as well as being used in the isolated working heart preparation.
The system includes a PowerLab, LabChart and LabChart Pro acquisition and analysis software. The analysis software includes the ADInstruments ECG Analysis and Blood Pressure Modules which are specifically configured to analyze and report pressure (ventricular or blood) parameters as well as examine any recordings of ECG. |
