Key result
A new method using a pneumatic arterial blood pressure sensor and synchronous ECG enables the estimation of pulse wave propagation velocity for diagnosing atherosclerosis.
Why the study?
The study was conducted to evaluate a new method for diagnosing atherosclerosis using a manual pneumatic arterial blood pressure sensor to measure pulse wave transit time relative to a synchronous ECG.
A novel method utilizing a pneumatic arterial blood pressure sensor and synchronous ECG provides a way to estimate pulse wave propagation velocity, which may aid in diagnosing atherosclerosis.
Pneumatic PWTT method may enable noninvasive atherosclerosis detection; hypothesis-generating and requires prospective validation before clinical use.
The paper discusses a new method for diagnosing atherosclerosis using a pneumatic arterial blood pressure sensor previously developed by the authors hereof. The possibility of applying a pneumatic sensor to measure the pulse wave transit time referring to a synchronous ECG is treated herein. The specification of the method consisting in the selection of the characteristic moment of the pulse wave as the timestamp, when measuring the signal transit time in relation to the R-peak of the synchronous ECG, is justified hereby. The averaged values of the wave transit time at different points of the artery, taking into account the variability of the front delay values, are used to directly determine the pulse wave propagation velocity in the area between the measurement points.
