S uperior vena cava (SVC) syndrome is an uncommon entity that affects approximately 15,000 Americans per year. Symptoms result from near or complete obstruction of the SVC and include facial and upper-extremity edema, chest pain, cough, dyspnea, dysphagia, proptosis, cyanosis, and headache. The severity of these symptoms relies upon the degree of SVC compression and the location of the obstruct...

1) How are SVC defined in these measurements? As stated in the manuscript, the presence of SVC was “detected” using the CPI, which defined the physical boundaries of SVC encountered by the C-130. Because the CPI was operational on every SVC flight, this optimized the definition of physical boundaries of SVC encountered by the WB-57F. Also, as explained in the manuscript, quantitative 2D-S measu...

A 49-year-old male was referred for catheter ablation for paroxysmal atrial fibrillation (PAF). PAF had recurred after each of 2 prior left atrial ablation procedures. He had a structurally normal heart with a left atrial diameter of 43 mm. The patient presented to the electrophysiology laboratory in AF with an average AF cycle length (CL) of 150 ms and reconnected pulmonary veins. After electr...

This paper describes the fuzzy boundaries between support verb constructions (SVC) with ter “have” and dar “give” and causative operator verb (VopC) constructions involving these same verbs, in Brazilian Portuguese (BP), which form a complex set of relations: (i) both verbs are the support verb of the same noun (SVC); (ii) dar is the standard (active-like) SVC while ter is a converse (passive-l...

In this paper the control strategies of svc are described.SVC is used to stabilize the voltage profile in a grid system.In the designing of SVC there is a combination of three TSC’s and one TCR.The SVC consists of a group of shunt connected capacitor banks and inductors with fast speed of response afforded by thyristor switching. The SVC provides the required amount of reactive power compensati...

A binary linear classification method, CGS method, was recently proposed by Gotoh and Takeda. The classification model was developed by introducing a risk measure known as the conditional value-at-risk (β-CVaR). CVaR minimization for the margin distribution leads to CGS problem, equivalent to ν-SVC of Schölkopf et al. in the convex case and Extended ν-SVC of Perez-Cruz et al. in the nonconvex c...

BACKGROUND Superior vena cava (SVC) is an infrequent yet an important source of atrial fibrillation. The clinical impact of ATP injection on arrhythmogenic SVC has not been evaluated. METHODS AND RESULTS A total of 43 patients (59±11 years; men, 32) who underwent ATP test for arrhythmogenic SVC after the electric isolation at either initial procedure or repeat procedure were included. Pulmona...

BACKGROUND The superior vena cava (SVC) has been proved to be a focal point in the initiation of paroxysmal atrial fibrillation. The autonomic nervous system plays an important role in the genesis of atrial fibrillation. However, the arrhythmogenic potentials of SVC and its responses to autonomic agents are not clear. The purpose of this study was to isolate single SVC cardiomyocytes and to inv...

BACKGROUND The purpose of this study was to clarify the relation between atrial defibrillation threshold (ADFT) for internal cardioversion (IC) and arrhythmogenicity of the superior vena cava (SVC). METHODS AND RESULTS A total of 159 consecutive patients (139 male, age 59.9±10.3 years) who underwent radiofrequency catheter ablation of atrial fibrillation (AF) were assessed. IC was performed i...
