A blood pressure survey was made of 400 physicians attending the 1965 American Medical Association annual convention. A double-blind technique was used to compare the usual clinical measurement with the electronic blood pressure monitor. The average age was 55.2 years. Mean blood pressure values by both methods were essentially identical and in the normal range. The electronic blood pressure monitor provides an efficient method of determining systolic and diastolic values.
