Result: 1) The prevalence of postprandial hypotension was 12.2% at 15mins, 25.7% at 30mins, 25.7% at 60mins after starting meals. 2) There was no significant difference in a9e, but there was significant difference in basal systolic blood pressure between responders and nonresponders to postprandial hypotension over the three different times. 3) There was no significant relation between the occurrence of postprandial hypotension and its related symptoms over the three different times.
