Objectives : The purpose of this study was to examine the relationship between changes in
pulmonary vascular resistance (PVR) and right ventricular ejection fraction (RVEF) and …

Background Longitudinal wall motion of the right ventricle (RV), generally quantified as
tricuspid annular systolic excursion (TAPSE), has been well studied in pulmonary hypertension (…

Background Until now, many investigators have focused on describing right ventricular (RV)
dysfunction in groups of patients with pulmonary arterial hypertension (PAH), but very few …

BACKGROUND: End-systolic elastance (E es ), a load-independent measure of ventricular
function, is of clinical interest for studies of the right ventricle (RV) in patients with pulmonary …

Background Interventricular mechanical dyssynchrony is a characteristic of pulmonary
hypertension. We studied the role of right ventricular (RV) wall stress in the recovery of …

OBJECTIVE: Sixteen different features are evaluated in their potential ability to detect
seizures from scalp EEG recordings containing temporal lobe (TL) seizures. Features include …

A windkessel model is widely used to operationalize vascular characteristics. In this paper,
we employ a noniterative subspace model identification (SMI) algorithm to estimate …

Simulations are useful to study the heart’s ability to generate flow and the interaction between
contractility and loading conditions. The left ventricular pressure–volume (PV) relation has …

Recently, it was shown that proportional relationships exist between systolic, diastolic and
mean pulmonary artery pressure (P sys , P dia and P mean ) and that they are maintained …

In pulmonary hypertension, exercise is limited by an impaired right ventricular (RV) stroke
volume response. We hypothesized that improvement in exercise capacity after pulmonary …
