We determined the capabilities and limitations of an experimental approach to measure segment work (force × distance) of myocardial regions in thein vivo beating heart. In 18 open-chest anesthetized dogs, segment length was measured using ultrasonic dimension transducers, and developed force was measured with miniature force transducers. Work was defined as the integrated multiples of instantaneous force and shortening during a single (averaged) beat, corresponding to the area under the length… CONTINUE READING
