Cryoablation is a new method in interventional cardiac electrophysiology for percutaneous catheter ablation of cardiac arrhythmias. Cryothermal mapping enables the functional assessment of a particular site before permanent ablation. In this way, the targeted tissue may be confirmed as safe for ablation. This is useful in high risk ablation, for example, nex to the His bundle or the compact AV ...

As the human race will continue to explore the space by creating new space transportation means and sending them to other planets, the enhance of atmospheric reentry study is crucial. In this context, an analysis of mass recession rate of ablative materials for thermal shields of reentry spacecrafts is important to be carried out. The paper describes a new estimation method for calculating the ...

reentrant tachycardia. Micro-reentry within the peripheral ramifications of the Purkinje system, and at Purkinje fiber-ventricular muscle junctions has been demonstrated in a variety of experimental preparations.13-l5 In each case the essential requirement has been the establishment of inhomogeneous conduction and unidirectional block. The arrhythmias generated in these laboratory models have a...

The ability to cure atrioventricular (AV) nodal reentry with radiofrequency catheter ablation with preservation of antegrade conduction represents a significant clinical advance. It also provides an opportunity to better understand the pathophysiology of this fascinating arrhythmia. Two techniques have been developed for ablation of AV nodal reentry. The first to be described used lesions made ...

Atrial flutter (AFL) is a common arrhythmia in clinical practice. Several experimental models such as tricuspid regurgitation model, tricuspid ring model, sterile pericarditis model and atrial crush injury model have provided important information about reentrant circuit and can test the effect of antiarrhythmic drugs. Human atrial flutter has typical and atypical forms. Typical atrial flutter ...

With record-high incarceration rates, unprecedented extension of state supervision over individuals leaving prison, and a complex maze of legal barriers to reintegration, more people than ever before are returning home after serving time in prison. These individuals face daunting barriers to successful reintegration. Successful reentry requires strong community support networks and comprehensiv...

This paper advances conceptualization of maternal distress following incarceration. We utilized a multiple case study methodology based on interviews with 10 mothers who demonstrated various permutations of "the triple threat" (depression, domestic violence, and substance abuse; Arditti & Few, 2006). Findings suggest that depressive symptomology persisted and worsened for mothers in our study a...

Ventricular arrhythmias (VA) can develop in patients with structural heart disease (SHD) including prior myocardial infarction and nonischemic cardiomyopathy. When VAs manifest in structurally normal hearts, they are usually a result of intra-cellular calcium overload (triggered activity) or an abnormal response to adrenergic stimulation (automaticity).1 Reentry within the Purkinje fibers and s...

Upper loop reentry is a rare type of non isthmus-dependent atrial flutter with a reentry circuit around the superior vena cava. We present a case of atrial flutter of this type in a 75-year-old man with concomitant sick sinus syndrome. The diagnostic approach used three-dimensional electroanatomical mapping with the upgraded ENSITE 3000 system. This is the first case to be described where, apar...

Objectives: The purpose of this study was for evaluation of relationship between hand function and age, sex by Jebson Taylor Test.This study determined whether age might be a factor when associated with sex. Methods: In this study Jebson Taylor was evaluated on hand in 180 normal males and females (0.50% male, 0.50% female) in each of the following 7 subtest in 3 age groups: (15-25), (35-45)...
