Ventricular defibrillation: appropriate energy levels.

Energy levels for biphasic defibrillation.

Defibrillators which deliver biphasic waveforms are rapidly replacing defibrillators which deliver monophasic waveforms. Lower energy biphasic shocks cause less myocardial injury and subsequent post-resuscitation myocardial dysfunction thus potential improving the likelihood of survival.(1-4) Recommendations of the International Liaison Committee on Resuscitation (ILCOR) state that biphasic ene...

Electrical energy requirements for ventricular defibrillation.

Long-term evaluation of the ventricular defibrillation energy requirement.

INTRODUCTION Defibrillation energy requirements in patients with nonthoracotomy defibrillators may increase within several months after implantation. However, the stability of the defibrillation energy requirement beyond 1 year has not been reported. The purpose of this study was to characterize the defibrillation energy requirement during 2 years of clinical follow-up. METHODS AND RESULTS Th...

Spontaneous ventricular defibrillation.

* The British Heart J'ournal welcomes letters commenting on papers that it has published within the past six months. * All letters must be typed with double spacing and signed by all authors. * No letter should be more than 600 words. * In general, no letter should contain more than six references (also typed with double spacing). Permanent pacing after cardiac trans-plantation SIR,-Scott et al...
