Does the dual-field conductance method improve the accuracy of left ventricular volume measurement compared to the single-field method in humans?
The dual-field conductance method provides more accurate measurement of left ventricular volume than the single-field method by improving segmental stroke volume estimation at the apex and base.
Hayashi et al. (1996) studied this question.
