Abstract
Technical characteristics of a fully automatic apparatus* for ambulatory semicontinuous blood pressure monitoring are described. Initially, we ascertained the reliability and the fidelity in the reproduction of studied events (blood pressure, heart rate, ECG). Good results were obtained, even in comparison with other methods (blood pressure semiautomatic or invasive monitoring). We then studied the results of the research on 200 hypertensive subjects. The easy applicability of this method allowed us to demonstrate blood pressure variability over a 24-h patient period. We now can evaluate the factors contributing to blood pressure variability and the alterations contributing to the meaning of circadian rhythm. We are now able to comment on the prevalent incidence of organic or neurogenic components in single hypertensive states, the possible coexistence of asymptomatic coronary heart disease, and on the choice and efficacy of hypotensive drugs.
