Daily profile of baroreflex sensitivity and the variability of blood pressure in essential hypertensive patients. 1981

J Ogawa, and S Arai, and S Takata, and T Ikeda, and T Takabatake, and N Hattori, and G Nomura

1. We have monitored intra-arterial pressure continuously throughout the day and analysed every beat by computer. 2. Baroreflex sensitivity (ms/mmHg) was measured four times a day (07.00, 12.00, 17.00 and 20.00 hours) in seven patients and three times a day (07.00, 12.00 and 17.00 hours) in 23 patients. The diurnal variation of baroreflex sensitivity in individual patients was 0--5.3 ms/mmHg and was not consistent. Mean baroreflex sensitivity was reduced in hypertensive patients compared with normotensive subjects. 3. A negative correlation was seen between baroreflex sensitivity and the variability of systemic blood pressure. 4. Baroreflex sensitivity was well correlated with the variability of heart rate.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
