Hypothesis-generating for defibrillator energy optimization in animals; leaves open translation to human ICD programming.
The relationship between defibrillation success rate and energy is best described by an exponential curve, which can help optimize energy efficiency in implantable defibrillators.
Gliner et al. (1990) studied Ventricular fibrillation (n=10). Defibrillation energy pulse was evaluated on Defibrillation success rate versus energy relationship. The exponential curve best describes the defibrillation success rate versus energy relationship, with the most efficient energy of 4.34 J achieving a 70% success rate.
