An example system includes memory configured to store a plurality of lead impedances (LeadZs) and processing circuitry communicatively coupled to the memory. The processing circuitry is configured to determine a first sensed LeadZ, and determine a second sensed LeadZ. The processing circuitry is configured to determine a first difference between the first sensed LeadZ and the second sensed LeadZ, and determine a parameter based at least in part on the first difference. The first sensed LeadZ and the second sensed LeadZ are sensed during a same first cardiac cycle or adjacent cardiac cycles of a heart that is receiving pacing.

Lead impedance measurement for physiological and device management

This disclosure is directed to devices, systems, and techniques for identifying a respiration rate based on an impedance signal. In some examples, a medical device system includes a medical device including a plurality of electrodes. The medical device is configured to perform, using the plurality of electrodes, an impedance measurement to collect a set of impedance values, where the set of impedance values is indicative of a respiration pattern of a patient. Additionally, the medical device system includes processing circuitry configured to identify a set of positive zero crossings based on the set of impedance values, identify a set of negative zero crossings based on the set of impedance values, and determine, for the impedance measurement, a value of a respiration metric using both the set of negative zero crossings and the set of positive zero crossings.

Sensing respiration parameters based on an impedance signal

The present invention includes systems, devices, and methods relating to the monitoring of the functional maturation of biological interventions effecting cardiac pacing; the systems, devices, and methods including an implantable electronic pulse generator delivering artificial cardiac pacing; a means for halting the electronic pulse generator delivering artificial cardiac pacing at predetermined data collection intervals; and a sensor for recording and storing data on one or more intrinsic physiological parameters of cardiac pacing during the predetermined data collection intervals.

System and apparatus to monitor biopacemaker maturation

A cardiac ischemic protection system and method for conditioning a patient's heart is provided. The method can include detecting acute myocardial infarction, angina pectoris, silent ischemia, or stunning and providing closed-loop dyssynchronous pacing to the patient's heart to precondition and/or postcondition the patient's heart in order to reduce ischemic damage.
