A noninvasive measure of baroreflex sensitivity without blood pressure measurement.
BACKGROUND Baroreflex sensitivity (BRS) and heart rate variability (HRV) are attenuated in cardiovascular disease and can give important prognostic information. Conventional measures of BRS require expensive or invasive equipment for the beat-to-beat measure of blood pressure (BP). We examined the possibility of developing a simple protocol that would provide a relatively standardized BP stimul...
متن کامل[Noninvasive, indirect measurement of pulmonary artery pressure].
OBJECTIVE The gold standard for measuring pulmonary artery pressure (PAP) is right heart catheterization. However, the usefulness of this technique is limited in patients with lung disease because of a poor acoustic window. The aim of this study was to assess PAP in a group of healthy persons using a noninvasive, indirect measurement procedure derived from the venous return flow velocity wave. ...
متن کاملNoninvasive Blood Pressure Measurement Methods
This paper review the historical background of noninvasive blood pressure measurement methods with their accuracies achieved and explains the requirements for common national and international standards of accuracy. Also are shortly described the development of blood pressure measurement system and a method, named electronic palpation method (EP), suitable for the long-term measurement of heart...
متن کاملDiminished baroreflex sensitivity in high blood pressure.
as the millisecond increase in cycle length per mm Hg rise in systolic pressure. The slope is an index of baroreflex sensitivity and was found to have an average value of 12.8 in 18 subjects without hypertension and 2.8 in 12 others with hypertension. When all results were pooled, there was an inverse relationship between the resting mean arterial pressure and slope of the baroreflex regression...
متن کاملAutomatic noninvasive measurement of systolic blood pressure using photoplethysmography
BACKGROUND Automatic measurement of arterial blood pressure is important, but the available commercial automatic blood pressure meters, mostly based on oscillometry, are of low accuracy. METHODS In this study, we present a cuff-based technique for automatic measurement of systolic blood pressure, based on photoplethysmographic signals measured simultaneously in fingers of both hands. After in...
