AUTOMATIC VECTOR SELECTION FOR MULTI-SITE PACING

摘要

Systems and methods for evaluating multiple candidate electrostimulation vectors for use in therapeutic cardiac stimulation are disclosed. The system can include a programmable electrostimulator circuit for delivering electrostimulation to one or more sites of a heart according to multiple candidate electrostimulation vectors. One or more physiologic sensors can detect resulting physiologic responses to the electrostimulation. A processor circuit can generate categories of indicators including therapy efficacy indicators, battery longevity indicators, or complication indicators using the sensed physiologic responses. The candidate electrostimulation vectors can be ranked according to the categories of indicators in specified orders. The system can include a user interface for displaying the ranked candidate electrostimulation vectors, and allowing the user to select one or more electrostimulation vectors and programming the electrostimulator circuit to deliver therapeutic electrostimulation to at least one site of the heart using the selected electrostimulation vectors.
