SYSTEMS AND METHODS FOR FACILITATING SELECTION OF ONE OR MORE VECTORS IN A MEDICAL DEVICE

摘要

Systems and methods may facilitate selection of a vector for delivering electrical stimulation to a patient's heart. One illustrative method may include delivering electrical stimulation at a first voltage to each vector in a first set of two or more vectors of a multi-vector medical system, determining whether the delivered electrical stimulation at the first voltage resulted in capture for each of the vectors in the first set of two or more vectors, identifying those vectors of the first set of two or more vectors that were determined to result in capture as a second set of vectors, delivering electrical stimulation at a second voltage that is lower than the first voltage to each vector in the second set of vectors, and determining whether the delivered electrical stimulation at the second voltage resulted in capture for each of the vectors in the second set of vectors.

1. A method for determining a capture threshold for one or more vectors of a multi-vector medical system, the method comprising:
delivering electrical stimulation at a first voltage to each vector in a first set of two or more vectors of the multi-vector medical system; determining whether the delivered electrical stimulation at the first voltage resulted in capture for each of the vectors in the first set of two or more vectors; identifying those vectors of the first set of two or more vectors that were determined to result in capture as a second set of vectors; delivering electrical stimulation at a second voltage that is lower than the first voltage to each vector in the second set of vectors; and determining whether the delivered electrical stimulation at the second voltage resulted in capture for each of the vectors in the second set of vectors.
