Fig. 4From: Early dynamic left intraventricular obstruction is associated with hypovolemia and high mortality in septic shock patientsPre- and postfluid bolus comparison. Comparison of intraventricular obstruction gradient before and after a single 500 ml fluid bolus; points correspond to mean values and error bars to two standard errors of the mean. The difference before and after volume expansion was statistically different (p = 0.001)Back to article page
