Abstract A method and apparatus (44) for measuring subthreshold defibrillation electrode resistance are disclosed. A known subthreshold current pulse is sourced across the electrodes (1, 2), the resulting voltage is measured and the electrode resistance is calculated from these values. The calculated electrode resistance may be utilized to adjust the energy level of a defibrillation shock used to treat a detected tachyarrhythmia. In one embodiment the calculated resistance and a predetermined leading edge voltage are used to calculated and adjust the duration of the defibrillation shock. In another embodiment the calculated electrode resistance and a predetermined shock duration are used to adjust the leading edge voltage of the defibrillatin shock.
