4. Apparatus comprising:
-
an electrode device, which comprises one or more device first electrode contact surfaces, and which is configured to be placed in a vicinity of a nerve of a subject at a first location neither within nor in contact with a heart of the subject; at least one second electrode contact surface, which is not directly mechanically coupled to the electrode device, and which is configured to be positioned in a body of the subject at a second location neither within nor in contact with the heart; and a control unit, which comprises; a sensing unit, which is configured to sense, using at least one of the device first electrode contact surfaces and the at least one second electrode contact surface, an electrical signal; and an analysis unit, which is configured to analyze the signal to identify a parameter of a cardiac cycle of the subject. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
