Abstract
Methods of implanting at least one lead for a cardio defibrillator using body surface potential (BSP) electrodes are disclosed. The methods may include installing defibrillation electrodes in a patient, attaching at least three BSP electrodes to the patient'"'"'s skin, creating a potential difference between the defibrillation electrodes, and measuring the resulting body surface potential at the three BSP electrodes. Once the resulting BSP is measured, the methods may include determining the amplitude of a resultant vector formed by the measured BSP potential differences. The location of a defibrillation electrode may then be manipulated to increase the amplitude of the resultant vector formed by the measured BSP potential differences.
