Implication

Impedance models may enable catheter LV volumetry; leaves open in vivo validation before any clinical use.

Structured PICO

Population

Spheroidal model of the left ventricle and post-mortem canine heart

Intervention

Analytical calculation of electrical impedances between catheter electrodes using eigen function expansions of the Laplace equation

Comparator

Experimental values of conductances measured post mortem in a canine heart

Outcome

Electrical impedances and total conductance of the ventriclesurrogate

Analytical models of electrical impedance for a catheter can estimate left ventricular volume, with theoretical results evaluated against post-mortem canine measurements.
