Fig. 4From: Heart defibrillation: relationship between pacing threshold and defibrillation probabilityCurves obtained from the sigmoidal adjustment of the normalized defibrillation probability result as a function of the electric field (×Threshold). Vertical lines indicate standard error of the mean (SEM). a Curves of the durations 0.2-, 0.5- and 1-ms. b Curves of durations 3-, 5-, 8- and 10-ms. Curves were fitted by Eq. (3), n = 10Back to article page
