these patients,' but we found this not to be the case. Our findings accord with those of Dustan et al, who found that most patients with angiographic evidence of renal artery disease did not have hypertension.3 It could be argued that angiographic evidence of renal artery disease does not necessarily indicate a functionally important stenosis, hence the poor relation between angiographic findin...

How should diastolic blood pressure be defined during pregnancy?

Controversy exists concerning the most accurate method for defining diastolic blood pressure in pregnancy. Both disappearance (phase V) and muffling (phase IV) of Korotkoff sounds have been advocated. We previously reported an objective noninvasive method for measuring blood pressure, called K2 analysis, which in nonpregnant subjects was not different from intra-arterial diastolic blood pressur...

Blood pressure recording in children.

Long, M., Dunlop, J. R., and Hoiland, W. W. (1971). Archives of Disease in Childhood, 46, 636. Blood pressure recording In children. Blood pressure levels for 148 children aged 0-14 years were recorded. Two different methods of measurement (the standard sphygmomanometer and the random-zero machine) and two cuffs of varying size were used on each child. Measurements of arm size and pulse rate we...

Observer error in recording arterial blood pressure.

The recording of blood pressure with a mercury manometer is subject to variation from two main sources, the individual observer error and change due to time sequence when repeated observations are recorded in a particular subject. The object of this paper is to study the observer error as between two observers in the estimation of blood pressure. This analysis is based on data derived from the ...
