Figure 2 Right ventricular end-diastolic area (open square = control subjects; solid squares = patients with HCM) and left ventricular end-diastolic dimension (open circles = control subjects; solid circles = patients with HCM) in the supine position and at different degrees of head-up tilting. #p < 0.01 vs. supine position. *p < 0.01 vs. corresponding value in control subjects. **p < 0.01 vs. immediately lower tilting degree.
