Pulse transit time based respiratory rate estimation with singular spectrum analysis

Time Series Forecast with Singular Spectrum Analysis

We propose a novel approach for constructing Singular Spectrum Analysis (SSA) forecast based on estimating new coefficients of Linear Recurrent Formula. The results indicate that the proposed method is more reliable in comparison to the widely used approaches that were proposed along with SSA. We conduct simulation studies to compare the relative performance of the new method with the existing ...

Estimation of aortic pulse wave transit time in cardiovascular magnetic resonance using complex wavelet cross-spectrum analysis

BACKGROUND Aortic pulse wave velocity (PWV), which substantially increases with arterial stiffness and aging, is a major predictor of cardiovascular mortality. It is commonly estimated using applanation tonometry at carotid and femoral arterial sites (cfPWV). More recently, several cardiovascular magnetic resonance (CMR) studies have focused on the measurement of aortic arch PWV (archPWV). Alth...

Toward a Smartphone Application for Estimation of Pulse Transit Time

Pulse transit time (PTT) is an important physiological parameter that directly correlates with the elasticity and compliance of vascular walls and variations in blood pressure. This paper presents a PTT estimation method based on photoplethysmographic imaging (PPGi). The method utilizes two opposing cameras for simultaneous acquisition of PPGi waveform signals from the index fingertip and the f...
