Abstract :
Conductance catheterisation can be used to measure intraventicular volume during the cardiac cycle in continuous real time. However, for pressure-volume loop analysis in cardiology, the conductance catheterisation needs more to be developed. This paper presents use of a microelectronic pressure sensor to develop the conductance catheterisation. Results show how possible to use the developed conductance catheter, called pressure-volume (PV) catheter, to estimate cardiac function.
