Determining Ejection Fraction Volumes on a Continuous Basis

IntroductionPeople with progressive heart failure need ejection fraction (EF) measurements as critical information in diagnosis and treatment. EF is the percentage of the total volume in a ventricular chamber of the heart that is ejected per beat, a key measure of overall heart function. A technology allowing continuous monitoring of EF would allow...

Continuous Monitoring of Cardiac Output and Left Atrial Pressure

IntroductionCardiac output (CO) is the volume of blood ejected by the heart per unit time, while left atrial pressure (LAP) is the blood pressure in the left heart during the cardiac filling phase. Both CO and LAP permit the diagnosis of various cardiovascular disease processes and thereby facilitate imminent therapeutic decisions. Thus, the ability...
