A Prospective, Randomized Study
Background Recent development of a prototype singlelead unipolar transvenous defibrillator offers the possibility of device implantation with the ease of a permanent pacemaker. Lowering defibrillation energy requirements would allow for a further reduction in defibrillator generator size and enhance the feasibility of pacemaker-like placement. However, if achieving a lower defibrillation energy...
متن کاملTedisamil increases coherence during ventricular fibrillation and decreases defibrillation energy requirements.
INTRODUCTION Drugs which primarily prolong cardiac refractoriness decrease defibrillation voltage and energy requirements in animals and man. The effect of such drugs on ventricular fibrillation itself is not well understood. We hypothesized that tedisamil, an investigational antiarrhythmic drug which blocks Ito and IK repolarizing potassium channels, would increase organization of epicardial e...
متن کاملSodium Channel Block and Action Potential Prolongation
Antiarrhythmic drugs have been reported to produce variable effects on defibrillation energy requirements. However, the relation between the in vitro electrophysiologic effects of these agents and the changes in defibrillation energy requirements have not been systematically examined. Therefore, we evaluated the effects of the sodium channel blocking drugs lidocaine and procainamide, the action...
متن کاملSystem for open-chest, multidirectional electrical defibrillation
Introduction: Cardiomyocytes are more sensitive to stimulatory electrical fields when the latter are applied longitudinally to the cell major axis. In the whole heart, cells have different spatial orientations, which may limit the effectiveness of conventional electrical defibrillation (i.e., shock delivery in a single direction). This article describes the constructive aspects of a portable sy...
متن کاملElectrical dose for ventricular defibrillation of large and small animals using precordial electrodes.
Electrical ventricular defibrillation of heavy subjects (over 100 kg body weight) is uncommon for the human or any animal species. This paper reports trans-chest ventricular defibrillation of subjects ranging in weight from 2.3 to 340 kg using conventional defibrillation current (heavily damped sine wave) of 0.3-30 ms duration. It was found that a body weight-to-electrical-shock strength relati...
