the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

We describe a simple method for left atrial pressure (LAP) monitoring from the right to the left atrium (LA) by a central line catheter. The anesthesiologist cannulates vena jugularis interna and inserts two central line catheters. One catheter is placed in the vena cava superior and the second single-lumen catheter is placed in the right atrium. The surgeon positions a one-line catheter from t...

The primary role of cardiac rate in adapting cardiac output to changing physiological needs has been more clearly recognized in recent years. Previously, the rate of cardiac stimulation had been determined either at pacemaker manufacture, by programming a single rate, or by sensing the atrium. More recently, sensing another physiological or nonphysiological function that changes in response to ...

background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...
