Myocardial functions can be characterized from ventricular pressure-volume relations. In small animals, the instantaneous ventricular volume is typically measured by using a miniaturized conductance catheter. In this work, a DSP-based conductance catheter measurement system is proposed, which adopts the admittance measurement method to estimate the(More)
The conductance catheter technique was developed in the 1980s to measure instantaneous ventricular conductance. After converting measured conductance to volume signals by use of the classic Baan conductance-to-volume equation, real-time pressure-volume (PV) relations can be obtained. A nonlinear conductance-to-volume conversion equation was proposed by Wei(More)
