In order to investigate the frequency of pseudohypertension in the elderly, intraarterial blood pressure was measured by inserting catheter into the brachial artery in 59 aged subjects more than 65 years old, and was compared with the simultaneously measured indirect cuff method. On average, systolic blood pressure of 161.5mmHg by cuff method was significantly lower than 169.2mmHg by direct method, although the significantly correlation was observed between both methods (y=0.93±19.3, r=0.94). A case that indirect cuff method overestimated systolic blood pressure more than 10mmHg, referred as pseudohypertension, was not observed in this study. Moreover, a significant difference of blood pressure between Osler positive's and netative's was neither observed in systolic nor diatolic. The present study showed that pseudohypertension was very rare phenomenon even in elderly subjects, in contrary with reports by some investigators.
