Antisymmetric Thermopolarization by Electric Toroidicity [PDF]

, 2021
We investigate electric polarizations emergent perpendicular to an applied thermal gradient in insulating systems. The thermally-induced electric polarization, known as thermopolarization, has been studied conventionally in the case that an electric polarization appears along the thermal gradient.

Electrical cardioversion during pregnancy: safe or not? [PDF]

, 2011
Two pregnant patients with a sustained symptomatic maternal supraventricular arrhythmia are presented. Both patients were treated with direct-current cardioversion.

Is there any Link Between Vitamin D and Recurrence of Atrial Fibrillation after Cardioversion? [PDF]

Brazilian Journal of Cardiovascular Surgery
Introduction: Atrial fibrillation (AF) is the most common chronic arrhythmia in the elderly population. In symptomatic patients, restoration and maintenance of sinus rhythm improve quality of life.

Advanced Cardiac Life Support Checklists for Simulation-based Education

MedEdPORTAL, 2014
Introduction A decade ago, we received feedback from nurses at our institution that the performance of medical residents at advanced cardiac life support (ACLS) events varied.

Electron-positron pair oscillation in spatially inhomogeneous electric fields and radiation [PDF]

Phys.Lett.B691:99-104,2010, 2010
It is known that strong electric fields produce electron and positron pairs from the vacuum, and due to the back-reaction these pairs oscillate back and forth coherently with the alternating electric fields in time. We study this phenomenon in spatially inhomogeneous and bound electric fields by integrating the equations of energymomentum and particle ...

Impact of major hurricanes on electric energy production [PDF]

arXiv, 2021
After major hurricanes, electric production is significantly reduced owing to not only electric infrastructure destruction, but also the economic crisis associated with damage to private and public activities. The full restoration of the electric infrastructure is not always simultaneously performed with the full restoration of electric production ...

Effectiveness of alternative shock strategies for out-of-hospital cardiac arrest: A systematic review

Resuscitation Plus, 2022
Aim: To determine the optimal first-shock energy level for biphasic defibrillation and whether fixed or escalating protocols for subsequent shocks are most effective.

The interplay between endogenous catecholamines and induced ventricular tachycardia during electrophysiologic testing [PDF]

, 1987
Plasma epinephrine and norepinephrine concentrations were measured before, during, and shortly after induced ventricular tachycardia (VT) in 22 selected patients.

Historical Development of Cardiac Pacing [PDF]

, 1971
I would like to discuss the development and historical aspects of cardiac pacemaking from a personal point of view, presented as it appeared to me over the years.

Ressuscitação cardiopulmonar com a utilização do desfibrilador externo semi-automático: avaliação do processo ensino-aprendizagem Resucitador cardiopulmonar con utilización del disfibrilador externo semiautomático: evaluación del proceso enseñanza-aprendizaje Cardiopulmonary resuscitation with semi-automated external defibrillator: assessment of the teaching-learning process

Revista da Escola de Enfermagem da USP, 2008
Estudos demonstram que a sobrevida após uma parada cardíaca diminui 10% para cada minuto de atraso na desfibrilação, e que a taxa de sobrevivência é de 98% quando ela é conseguida em 30 segundos.
