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;
an LV Offset determiner communicatively coupled to the user interface and configured to;
communicate a request to the implantable device for information in response to the prompt;
receive a representation of a cardiac signal sensed in the RV and a representation of a cardiac signal sensed in the LV from the implantable device;
measure a duration interval between a cardiac event in the RV and a cardiac event in the LV using the received representations;
calculate, as a first generated therapy setting, an LV offset interval using the measured duration interval and a previous value of a first indicated pacing interval; and
provide the calculated LV offset interval to at least one of a user or a process executing on the external medical device or a process of a different device.

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.

11. A method of operating an external device, wherein the external device is capable of communicating with an implantable device, the method comprising:
-
receiving a prompt via a user interface of the external device to generate one or more therapy settings for the implantable device; communicating a request to the implantable device for information in response to the prompt; receiving a representation of a cardiac signal sensed in the RV and a representation of a cardiac signal sensed in the LV in response to the communicated request; measuring, with the external device, a duration interval between a cardiac event in the RV and a cardiac event in the LV using the received representations of the sensed cardiac signals; calculating, as a first generated therapy setting, an LV offset interval using the measured duration interval and a previous value of a first indicated pacing interval; and providing the calculated LV offset to at least one of a user or a process executing on the external medical device or a process of a different device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
