1. Apparatus for use with a medical device, comprising:
- a sensing electrode configured to be implanted at a non-cardiac site in a vicinity of an aorta of a subject and to detect an electrical parameter of the aorta; and
a control unit configured to;
receive the detected parameter,extract first and second signal components from the detected parameter,derive an ECG cycle of the subject, from the first component of the detected parameter,derive a mechanical event within the aorta, from the second component of the detected parameter, andin response to at least one derived parameter selected from the group consisting of;
the derived ECG cycle, and the derived mechanical event, control the medical device.
