Why the study?
Can simultaneous recording of left ventricular pressure and echocardiographic volume accurately assess left ventricular pressure-volume relations in humans?
Can simultaneous recording of left ventricular pressure and echocardiographic volume accurately assess left ventricular pressure-volume relations in humans?
Simultaneous recording of left ventricular pressure and echocardiographic volume provides a feasible, beat-to-beat method for analyzing left ventricular pressure-volume relations and stroke work in humans without relying on quantitative angiography.
