Estimation of Systolic and Diastolic Pressure using the Pulse Transit Time
In this paper, algorithm estimating the blood pressure was proposed using the pulse transit time (PTT) as a more convenient method of measuring the blood pressure. After measuring ECG and pressure pulse, and photoplethysmography, the PTT was calculated from the acquired signals. Thereafter, the system to indirectly measure the systolic pressure and the diastolic pressure was composed using the ...
متن کاملBlood Pressure Estimation based on Pulse Transit Time and Compensation of Vertical Position
A chronically high blood pressure (BP) may lead to arteriosclerosis and consequently is a risk factor for apoplectic stroke and cardiac infarction – the main death causes in industrial countries. Hence, blood pressure recently has become one of the most relevant parameters for the assessment of a patients’ health status. For the purpose of a continuous monitoring of cardiovascular patients, we ...
متن کاملA Comparative Study in the Use of Brachial Photoplethysmography and the Qrs Complex as Timing References in Determination of Pulse Transit Time
For more than a century, there has been interest in pulse wave velocity and pulse transit time as a possible metric for blood pressure and other cardiovascular parameters. The most common approach in noninvasive measurement of these metrics has been to measure the time delay between the QRS complex on the electrocardiograph and the detection of the finger photoplethysmograph. This paper introdu...
متن کاملValidation of a new non-invasive blood pressure measurement method on mice via pulse wave propagation time measurement on a cuff.
In the present article, we describe the validation of a new non-invasive method for measuring blood pressure (BP) which also enables to determine the three BP values: systolic, diastolic and mean value. Our method is based on the pulse transit time (PTT) measurement along an artery directly at the BP cuff. The accuracy of this method was evaluated by comparison with the direct simultaneous meas...
متن کاملUse of pulse transit time as a measure of inspiratory effort in patients with obstructive sleep apnoea.
Pulse transit time (PTT) is the time taken for the arterial pulse pressure wave to travel from the aortic valve to a peripheral site. For convenience, it is usually measured from the R wave on the electrocardiogram to the pulse wave arrival at the finger. Pulse transit time is inversely proportional to blood pressure, and the falls in blood pressure which occur with inspiration (pulsus paradoxu...
