Introduction to Echocardiography
where SF = shortening fraction, LVEDD = left ventricular end-diastolic dimension, and LVESD = left ventricular end-systolic dimension. Normal values vary with age and range from 35–45 % in infants to 28–44 % in adolescents and…
Blood Pressure, Heart Tones, and Diagnoses
where PP = SBP − DBP, MAP = mean arterial pressure, DBP = diastolic blood pressure, PP = pulse pressure, and SBP = systolic blood pressure. Blood flow throughout the circulatory system follows pressure gradients. By the time blood reaches the right…
