Cite This Study
Harvey Feigenbaum (1968) conducted an observational in Normal subjects and patients undergoing necropsy or open-heart surgery (n=60). Pulsed reflected ultrasound vs. Direct measurement at necropsy or during open-heart surgery was evaluated on Accuracy of left ventricular wall thickness measurement. Pulsed reflected ultrasound accurately measured left ventricular wall thickness compared to direct measurements at necropsy or during open-heart surgery in 60 subjects.
