LEFT VENTRICULAR PRESSURE (LVP) ANALYSIS
Automatic LVP Analysis
 
 
Calculate and record left ventricular pressure (LVP) data from acute, chronic and isolated heart preparations. Use the MPMS100A-1/MPMS100A-2 Micro Pressure Measurement System for small vessel recordings, including mouse left and right ventricular blood pressure. Interface with a variety of invasive transducers, including the popular series of Millar Mikro-Tip Catheters.
 
AcqKnowledge extracts various cycle-by-cycle cardiac measures of left ventricular blood pressure data, optionally in conjunction with an ECG Lead II signal. Examines the LVP signal, ECG, and derivative of the LVP signal.
 
  • If the LVP and ECG signals have not been classified before this analysis is executed, they will be classified automatically.
  • Derivatives of the LVP signal can be pre-existing or can be constructed automatically.

The analysis outputs the following information on a cycle-by-cycle basis and the textual output cites the average of all of these cycle-by-cycle measurements:
