Patent ID: 8521285

Claim:
An apparatus comprising: a processor circuit, configured by performing instructions to: receive, from a memory, a parameter characteristic of a function of: (1) a plurality of first electrostimulation capture thresholds associated with a first vector defined by a first electrode associated with a left ventricle and at least one other electrode that is located other than in association with the left ventricle, and (2) a plurality of second electrostimulation capture thresholds associated with a second vector defined by the first electrode and a second electrode that is also associated with the left ventricle; receive a third electrostimulation capture threshold associated with the first vector; and use (1) the third electrostimulation capture threshold associated with the first vector, and (2) the parameter characteristic of the function, to determine a fourth electrostimulation capture threshold associated with the second vector; and an electrostimulation circuit, coupled to the processor, and configured to deliver an electrostimulation using the second vector, wherein the electrostimulation exceeds the fourth electrostimulation capture threshold.
