J. Neuzner et al., EFFECTS OF ELECTRODE POLARITY ON DEFIBRILLATION THRESHOLDS IN BIPHASIC ENDOCARDIAL DEFIBRILLATION, The American journal of cardiology, 78(1), 1996, pp. 96
The defibrillation thresholds of both first-phase polarities of a biph
asic waveform were tested using an endocardial defibrillation electrod
e system. Despite differences in defibrillation thresholds in the indi
vidual patient, both tested electrode polarities lead to a comparable
overall defibrillation efficacy.
