Dual-excitation may refine conductance catheter accuracy in animal models; leaves open human validation before any clinical consideration.
Does the dual-excitation conductance method improve the accuracy of left ventricular stroke volume estimation compared to the single-excitation method in dogs?
The dual-excitation conductance method provides more accurate and linear estimations of left ventricular stroke volume compared to the conventional single-excitation method in an open-chest dog model.
