Comparison of activation during ventricular fibrillation and following unsuccessful defibrillation shocks in open-chest dogs.
The purpose of this study was to map in detail the spread of activation away from sites of early postshock excitation following unsuccessful defibrillation to determine whether these activation fronts are the unaltered continuation of activation fronts present just before the shock. We recorded simultaneously from 120 bipolar electrodes on 40 plunge needles in a 20 x 35 x 5-mm volume of tissue ...

متن کاملHigh dispersion of ventricular repolarization after an implantable defibrillator shock predicts induction of ventricular fibrillation as well as unsuccessful defibrillation.
OBJECTIVES To test the hypothesis that post-shock dispersion of repolarization (PSDR) is higher in T wave shocks that induce ventricular fibrillation (VF) than in those that do not, as well as in implantable cardioverter defibrillator (ICD) defibrillation shocks which fail to terminate VF when compared with those that are successful. BACKGROUND Ventricular fibrillation has been linked to the ...
متن کاملActivation during ventricular defibrillation in open-chest dogs. Evidence of complete cessation and regeneration of ventricular fibrillation after unsuccessful shocks.
To test the hypothesis that a defibrillation shock is unsuccessful because it fails to annihilate activation fronts within a critical mass of myocardium, we recorded epicardial and transmural activation in 11 open-chest dogs during electrically induced ventricular fibrillation (VF). Shocks of 1-30 J were delivered through defibrillation electrodes on the left ventricular apex and right atrium. ...
متن کاملImmediate defibrillation or defibrillation after cardiopulmonary resuscitation.
OBJECTIVES This study aimed to determine whether short cardiopulmonary resuscitation (CPR) by emergency medical services before defibrillation (CPR first) has a better outcome than immediate defibrillation followed by CPR (shock first) in patients with ventricular fibrillation/pulseless ventricular tachycardia (VF/pulseless VT) out-of-hospital cardiac arrest. METHODS We analyzed a national da...
