Echocardiographic assessment of dyssynchrony: moving forward.
Correction of mechanical dyssynchrony is believed to be the primary mechanism by which cardiac resynchronization therapy (CRT) improves clinical status and reduces left ventricular (LV) volume.1 The use of QRS duration as a surrogate for mechanical dyssynchrony has been intensely investigated, based on the suspicion that a direct measurement of mechanical rather than electric dyssynchrony might...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Usefulness of left ventricle dyssynchrony assessment before cardiac resynchronization implantation.
BACKGROUND A number of trials have demonstrated the effect of cardiac resynchronization therapy (CRT) on functional improvement and reversed left ventricle remodeling. Meeting contemporary guidelines approximately 30- 40% of patients do not respond to CRT (non-responders). AIM To quantify the predictive ability of basal QRS width and basal echocardiographic parameters of left ventricle contra...

ventricle, and single ventricle (Figure 1). The results from the single center, which is one of the most experienced, highvolume institutes in Japan, showed CRT benefit in patients with systemic left or single ventricular morphology. However, 7 patients with systemic right ventricle (RV) did not achieve apparent 6-month response from CRT, showing no effect on ardiac resynchronization therapy (C...
متن کاملRelaxed Differential Fault Analysis of SHA-3
In this paper, we propose a new method of differential fault analysis of SHA-3 which is based on the differential relations of the algorithm. Employing those differential relations in the fault analysis of SHA-3 gives new features to the proposed attacks, e.g., the high probability of fault detection and the possibility of re-checking initial faults and the possibility to recover internal state...
