Ventricular defibrillation with triphasic waveforms.
BACKGROUND It has been reported that triphasic defibrillation waveforms cause less myocardial injury than biphasic waveforms. This study compared the defibrillation thresholds (DFTs) of triphasic and biphasic waveforms. METHODS AND RESULTS ++DFTs were determined for a transvenous lead system and a 300-microF-capacitor defibrillator. In 8 pigs (group 1), DFTs were determined for 5 triphasic wa...
متن کاملImproved defibrillation thresholds with large contoured epicardial electrodes and biphasic waveforms.
A reduction in the shock strength required for defibrillation would allow use of a smaller automatic implantable cardioverter-defibrillator and would reduce the possibility of myocardial damage by the shock. Most internal defibrillation electrodes require 5 to 25 J for successful defibrillation in human beings and in dogs. In an attempt to lower the shock strength needed for defibrillation, we ...
متن کاملSimultaneous Comparison of Many Triphasic Defibrillation Waveforms
Biphasic defibrillation waveforms are now accepted as being more effective at terminating ventricular fibrillation (VF) than monophasic waveforms. If two phases are better than one, this naturally leads to the hypothesis that additional phases improve efficacy. This study tests the hypothesis by adding one additional phase. We examined the efficacy of 18 different triphasic waveforms simultaneo...
متن کاملDistally based sural artery flap without sural nerve.
The distal third of the tibia, ankle and heel area is difficult to reconstruct. For small to medium size defects, local flaps are often an easier alternative than free flap. In lower limb surgery, the sural flap is based on this principle and this flap is becoming increasingly popular. The distally based superficial sural artery flap, first described as a distally based neuro skin flap by masqu...
متن کاملChronic Defibrillation Thresholds in Nonthoracotomy Implantable Defibrillator
Background To establish the chronic stability of defibrillation thresholds (DFTs) in a transvenous cardioverter/defibrillator (TCD) system, we studied 37 consecutive patients with TCD systems implanted for >6 months. Methods and Results DFT was measured by a step-down method at implant and 2 and 6 months later. The mean ejection fraction was 34.5±14.3%. Coronary artery disease with previous myo...
