Pulse Wave Transit Time and Its Relationship with Systolic Blood Pressure

Blood pressure is one of important parameter in assessing patients’ health status. The measurement of blood pressure using conventional method is less practical in monitoring continuous blood pressure. This paper proposed an automatic technique for monitoring blood pressure continuously using the relation of pulse wave transit time (PWTT) with systolic blood pressure (SBP). The measurement of PWTT involves the marking of electrocardiograph R (ECG-R) peak from electrocardiograph (ECG) signal and the peak of peripheral pulse wave from photoplethysmography (PPG) signal. Data collection involves three different sessions, which are resting period, exercise period and recovery period, thus establishing the relationship between SBP and PWTT. The results of monitoring blood pressure based on pulse wave transit time will facilitate personal healthcare monitoring blood pressure continuously.

Relationship Study of Heart Rate and Systolic Blood Pressure for Healthy Peoples

Manual blood pressure measurement is not practical if it is taken frequently. Therefore, in this paper, an automatic measurement system that can measure systolic blood pressure (SBP) incessantly based on its relationship with a heart rate is introduced. The system examines the heart rate based on the electrocardiography (ECG) and its relationship with SBP from the healthy subjects. The data analysis involved resting period, exercise period and recovery period of the subject (human). The results show that the system is capable of determine an incessantly blood pressure monitoring technique based on heart rate using ECG. The use of liquid crystal display (LCD) to display a quick result demands more practical in measuring the blood pressure.
