I. Introduction
The MPVS Ultra simultaneously and continuously measures high-fidelity left ventricular
pressure and volume from the intact beating hearts of large and small laboratory animals.
The MPVS Ultra can be used on animals as small as transgenic mice and as large as full
grown horses. Using the MPVS Ultra, cardiovascular pressure and volume signals can be
plotted against each other in real time, generating the characteristic pressure-volume (P-V)
