In seventy-six unselected, untreated patients with essentia1 hypertension, the diastolic blood pressure was found to fluctuate widely during periods of observation extending in the individual case up to one and one-half years. The series of patients included those with advanced essential hypertension as well as those with milder forms. It was found that in all cases the diastolic blood pressure fluctuated over a wide range. The percentage of fluctuation was found to be as great as that of the systolic blood pressure. There was no appreciable difference between patients with severe hypertension and those with milder forms. The degree of fluctuation was found to vary to a certain extent with the number of observations made on the patient: the more frequent the observations, the greater the fluctuation recorded. The lowering effect on the diastolic blood pressure of sitting in a quiet room also seems definite and conversely, the elevating effect of rxcitement. There were no patients who had a fixed nonfluctuating hypertension.
