Understanding the Importance of PV Calibration in Admittance and Conductance Systems

Pressure-Volume (PV) Loops are the gold standard for measuring direct, real-time cardiac function. In this article, we’ll explore common shortcuts in calibration, and demonstrate how failing to perform the recommended calibration procedures can produce inaccurate results in both admittance and conductance PV systems.

Electrophysiology Studies Use Millar Catheters

Millar electrophysiology (EP) catheters can be used for standard electrophysiology studies by applying pacing and recording protocols from inside the heart (intracardiac) or through the esophagus (transesophageal), which determines electrical properties of the atrium and ventricle. This is a proven method for characterizing the electrical phenotype of transgenic mice, as well as determining and diagnosing detrimental heart conditions.
