1. A system comprising:
a display; and
a processing unit configured to:
receive torso-surface potential signals of a patient from a plurality of electrodes, wherein the received torso-surface potential signals comprise torso-surface potential signals sensed using a plurality of different electrode configurations,
for each electrode configuration of the plurality of different electrode configurations, determine a torso-surface activation time based on the torso-surface potential signal sensed from the respective electrode configuration,
present, via the display, indications of the torso-surface activation times for the plurality of electrode configurations, and
recommend a location for placement of a medical lead for delivering cardiac therapy to a heart of the patient based on the torso-surface activation times, wherein to recommend the location for placement of the medical lead, the processing unit is configured to:
determine, based on the determined torso-surface activation times, an estimated reduction in electrical dyssynchrony of the heart of the patient in response to the cardiac therapy, wherein the estimated reduction in electrical dyssynchrony of the heart indicates an efficacy of the recommended location of the medical lead for delivering the cardiac therapy, and
if the estimated reduction in electrical dyssynchrony during the cardiac therapy compared to an intrinsic rhythm is greater than a specified limit, select the recommended location and generate an output indicating that the recommended location provides an effective change in synchronization.
