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.

The Mechanisms of Digitalis-Induced Ventricular Fibrillation

, 1968
Two cases of digitalis induced ventricular fibrillation in which the onset of the arrhythmia was recorded electrocardiographically are presented. In the first patient, fibrillation evolved from a rapidly progressing bidirectional ventricular tachycardia.

Inhomogeneity of cellular activation time and Vmax in normal myocardial tissue under electrical field stimulation

, 1994
To clarify the mechanism underlying the ectopic excitation after countershock, the cellular activation processes of cardiac tissue with a low-potential-gradient electric field (LPEF) were investigated in experiments using guinea pig papillary muscles ...

Ultrastructural injury to chick myocardial cells in vitro following "electric countershock". [PDF]

Circulation Research, 1980
We studied the structural alterations that follow the application of currents similar to those used in clinical electric countershock procedures in cultured chick myocardial cells. Myocardial cells 48 hours in culture were subjected to electric field stimulation. The cells then were fixed for electron-microscope examination 30 seconds postshock.

Cardiac Pacemaker Battery Discharge After External Electrical Cardioversion for Broad QRS Complex Tachycardia

Indian Pacing and Electrophysiology Journal, 2008
External electrical cardioversion or defibrillation may be necessary in patients with implanted cardiac pacemaker (PM) or implantable cardioverter defibrillator (ICD).

Estudio de los mecanismos de las arritmias cardiacas mediante modelado y procesado robusto digital de señal [PDF]

, 2008
Las arritmias cardiacas son alteraciones del funcionamiento eléctrico normal del corazón. Algunas, las arritmias patológicas, son potencialmente malignas y constituyen una de las principales causas de mortalidad en el mundo occidental.
