Abstract:
1. A method of implanting at least one lead for a cardio defibrillator, comprising: a. installing a RV defibrillation electrode in a right ventricle of a patient's heart; b. installing a second defibrillation electrode in the patient; c. attaching at least three body surface potential (BSP) electrodes capable of measuring body surface potential to the patient's skin; d. creating a potential difference between the RV defibrillation electrode and the second defibrillation electrode; e. measuring the body surface potential at the at least three body surface potential (BSP) electrodes caused by the potential difference between the defibrillation electrodes; f. determining the amplitude of a resultant vector formed by the measured potential differences between the at least three body surface potential (BSP) electrodes, the measured potential differences between the at least three body surface potential (BSP) electrodes forming component vectors of the resultant vector; and g. manipulating the location of at least one of the defibrillation electrodes to increase the amplitude of the resultant vector formed by the measured potential differences between the at least three body surface potential (BSP) electrodes.
