The Interelectrode Electrical Resistance at Defibrillation

Abstract

A determination of electrical resistance over the living, human myocardium was performed during defibrillation. Measurements were made between electrodes directly applied on the naked heart as well as on the chest for external use. Internal defibrillations showed a resistance of 32.7 ohms, which is approximately half the value of earlier assumptions. This knowledge is important for the construction of good defibrillators.
