Towards Low Energy Atrial Defibrillation
A wireless powered implantable atrial defibrillator consisting of a battery driven hand-held radio frequency (RF) power transmitter (ex vivo) and a passive (battery free) implantable power receiver (in vivo) that enables measurement of the intracardiac impedance (ICI) during internal atrial defibrillation is reported. The architecture is designed to operate in two modes: Cardiac sense mode (pow...
متن کاملLow-energy atrial defibrillation: a promising new technique.
Temporary epicardial wire electrodes placed during open heart surgery for potential diagnostic and/or therapeutic use in patients in the immediate postoperative period have been used safely and effectively as part of standard care for a long time. We have also known that synchronized delivery of a low-energy DC shock for cardioversion of atrial fibrillation is very effective. With the presentat...
متن کاملLow-energy multistage atrial defibrillation therapy terminates atrial fibrillation with less energy than a single shock.
BACKGROUND Implantable device therapy of atrial fibrillation (AF) is limited by pain from high-energy shocks. We developed a low-energy multistage defibrillation therapy and tested it in a canine model of AF. METHODS AND RESULTS AF was induced by burst pacing during vagus nerve stimulation. Our novel defibrillation therapy consisted of 3 stages: stage (ST) 1 (1-4 low-energy biphasic [BP] shoc...
متن کاملHypothesis for low-energy transthoracic defibrillation.
timely and informative. The Belfast group has a prodigious experience in out-of-hospital resuscitation and their prospectively collected data have been invaluable in determining energy requirements for defibrillation. The evidence indicating the need for defibrillators storing more than 400 Ws is, at present, inadequate and unconvincing (Lown et al., 1978). In addition to the views expressed by...
متن کاملA prospective evaluation of two defibrillation safety margin techniques in patients with low defibrillation energy requirements.
INTRODUCTION In patients undergoing defibrillator implantation, an appropriate defibrillation safety margin has been considered to be either 10 J or an energy equal to the defibrillation energy requirement. However, a previous clinical report suggested that a larger safety margin may be required in patients with a low defibrillation energy requirement. Therefore, the purpose of this prospective...
