1. An apparatus for optimizing an implanted device in a candidate, the apparatus comprising:
- a first sensor configured to sense a tracing signal;
a transducer configured to capture an image of a region of interest, where the image is captured in synchronism with the tracing signal; and
a determiner configured to determine a cardiac functional value based on the image and the tracing signal,wherein a parameter of the implanted device is adjusted based on the cardiac functional value.

Abstract
An apparatus, a method and a protocol for optimizing an implanted device in a candidate. The apparatus comprises a first sensor configured to sense a tracing signal, a transducer configured to capture an image of a region of interest, where the image is captured in synchronism with the tracing signal, and a determiner configured to determine a cardiac functional value based on the image and the tracing signal. A parameter of the implanted device is adjusted based on the cardiac functional value.

28. A computer readable medium comprising a program for evaluating an implanted device in a candidate, the medium comprising:
-
a sensing code segment that, when executed by a computer, causes sensing a tracing signal; an image capturing code segment that, when executed by the computer, causes capturing an image of a region of interest in synchronism with the tracing signal; a cardiac functional value determining code segment that, when executed by the computer, causes determining a cardiac functional value based on the tracing signal and the image; a parameter adjusting code segment that, when executed by the computer, causes adjusting a parameter of the implanted device based on the cardiac functional value; and an improvement determining code segment that, when executed by the computer, causes determining whether a cardiac synchronization improvement is greater than or equal to a baseline based on the cardiac functional value.
