Left ventricular untwisting rate by speckle tracking echocardiography.
BACKGROUND Recent studies validated the measurement of left ventricular (LV) untwisting rate (UR) by speckle tracking echocardiography. A few reports suggest that it may provide additional noninvasive insight into LV diastolic function. METHODS AND RESULTS Simultaneous echocardiographic imaging and LV pressure measurements (7F Millar catheters) were performed in 8 adult dogs. Loading conditio...

متن کاملLeft ventricular strain and strain rate by two-dimensional speckle tracking echocardiography in patients with subclinical hypothyroidism.
AIM Subclinical hypothyroidism (SH) is an asymptomatic condition defined by increased serum thyroid-stimulating hormone (TSH) with normal free thyroid hormone levels. Heart is a major target organ for thyroid hormone action. The aim of this study was to evaluate cardiac functions in patients with SH by speckle tracking imaging. PATIENTS AND METHODS We included 23 consecutive patients with unt...
متن کاملThe influence of acute unloading on left ventricular strain and strain rate by speckle tracking echocardiography in a porcine model.
Noninvasive measurements of myocardial strain and strain rate by speckle tracking echocardiography correlate to cardiac contractile state but also to load, which may weaken their value as indices of inotropy. In a porcine model, we investigated the influence of acute dynamic preload reductions on left ventricular strain and strain rate and their relation to the pressure-conductance catheter-der...
