| description | The purpose of this work is to show the potential of Electromechanical Film (EMFi) sensor in local vascular elasticity studies via pulse wave velocity (PWV) obtained from limbs and radial arteries. ECG and pulse signals from the limbs were recorded from 48 working aged men in sitting position. Duration of the signal components (pulse transit time; PTT) from the foot point and from the peak of the ankle and radial pulse signals according to R wave of the ECG were studied. PWV parameters between left and right wrist and respectively between left and right ankle were compared with Bland-Altman (BA) plots and with Pearson correlation in order to study, whether foot point or peak point from the ankle and radial pulse give consistent information about vascular elasticity in the form of PWV.
Results show that elastic information in the form of PWV is obtainable from the ankle and radial pulse signals having variation which depends from the detected site of the pulse signal. Little more variation was seen in the PWV and Pearson correlation values obtained from the foot point of the signal utilizing PTT with a minimum method. As the differences between the obtained results were relatively small, both locations are at least suitable in PWV determination giving consistent information about vascular elasticity. The variation in the form of the pulse signal due to local elasticity changes may challenge accurate point detection in PWV studies. |
