EXPERT SYSTEM AND METHOD
First Claim
1. An external medical device to communicate with an implantable device, the external device comprising:
- a user interface configured to receive a prompt to generate one or more therapy settings for the implantable device;
a pacing site selector configured to;
receive a measure of a QRS complex duration into pacing site selector input;
measure a time of occurrence of a peak of depolarization of a right ventricle (RV) and a time of peak of occurrence of depolarization of a left ventricle (LV);
determine, as a first generated therapy setting, a pacing site according to the measure of QRS complex duration and the time relationship of the depolarization peak of the RV and the depolarization peak of the LV; and
provide the determined pacing site to at least one of a user or process.

Abstract
A medical device programmer and a method of operation in which a first data value is received and used in the execution of one or more algorithms. One or more suggested pulse generator settings are calculated from the one or more algorithms based on the first data value, and the one or more suggested pulse generator settings are displayed on an interactive display screen of the medical device programmer. In one embodiment, the first data value is a duration interval of a QRS complex. From the duration interval, suggestions are made as to one or more ventricular chambers in which to provide pacing pulses. Additionally, pacing intervals for an AV delay are suggested based on measured P-R intervals, or pacing intervals for an LV offset are suggested based on a measured duration interval of a V-V-interval between a right ventricular event and a left ventricular event.
