Abstract

In this paper, pulse transit time (PTT) was calculated based on wavelet transform modulus maxima (WTMM), for the estimation of blood pressure (BP). The mean and standard deviation of the differences between the estimated BP values and the values obtained from the standard BP meter were -2.6256 mmHg and 6.7459 mmHg fur systolic blood pressure, and -0.7901 mmHg and 6.1777 mmHg for diastolic blood pressure respectively. The results show that the WTMM-based BP estimation approach is quite promising.
