    Abstract: A cardiac pacemaker that delivers cardiac pacing therapy that includes delivering the cardiac pacing therapy from a cardiac pacing device, sensing a pacing event from a plurality of electrodes of the pacing device, and sensing an electromechanical signal from an electromechanical sensor of the pacing device. A pre-ejection period is determined in response to the sensed electromechanical signal, and a left ventricular ejection time is determined in response to the sensed electromechanical signal. The pacemaker device performs one or both of adjusting a pacing parameter setting and generating an alert in response to the determined pre-ejection period and the determined left ventricular ejection time.

    Abstract: The exemplary systems and methods may be configured to monitor electrical activity from a patient using a plurality of external electrodes. The exemplary systems and methods may be further configured to provide a model heart representative of the patient's heart based on at least one of a plurality of patient characteristics. The model heart can include a plurality of segments. The exemplary systems and methods may be further configured to determine a value of electrical activity for each of a plurality of anatomic regions of the model heart based on the mapped electrical activity. Each of the plurality of anatomic regions can include a subset of the plurality of segments.

    Abstract: A medical device and medical device system for determining capture during delivery of a ventricular pacing therapy that includes a subcutaneous sensing device comprising a subcutaneous electrode to sense a subcutaneous cardiac signal and to emit a trigger signal in response to the sensed cardiac signal, an intracardiac therapy delivery device capable of being implanted within a left ventricle of a heart to receive the trigger signal and deliver the ventricular pacing therapy to the left ventricle in response to the emitted trigger signal, and a processor positioned within the subcutaneous sensing device, the processor configured to compare a beat of the subcutaneous cardiac signal sensed by the sensing device subsequent to the ventricular pacing therapy being delivered to a baseline template associated with a non-paced beat, and determine whether the delivered ventricular pacing therapy captures the left ventricle in response to the comparing.

    Abstract: The present disclosure relates to cardiac evoked response detection and, more particularly, reducing polarization effects in order to detect an evoked response following delivery of a stimulation pulse. An implantable medical device (IMD) is configured to deliver a ventricular pacing pulse. A signal is sensed in response to the ventricular pacing stimulus. A window is placed over the sensed signal to obtain a set of data from the signal after a paced event. The set of data extracted from the sensed signal comprises a maximum amplitude, a maximum time associated with the maximum amplitude, a minimum amplitude, and a minimum time associated with the minimum amplitude. Responsive to processing the extracted data, the window is delayed to avoid polarization effects. A determination is then made as to whether the ventricular pacing stimulus is capturing the paced ventricle in response to determining whether the maximum time is greater than the minimum time.

    Abstract: A medical device system for controlling ventricular pacing therapy during cardiac resynchronization therapy that includes a sensing device to sense a cardiac signal and emit a trigger signal in response to the sensed cardiac signal, a therapy delivery device to deliver the ventricular pacing in response to the emitted trigger signal, and a processor configured to identify a fiducial point of the cardiac signal sensed in real-time, set a window comprising a start point positioned a first distance prior to the fiducial point and an endpoint positioned a second distance less than the first distance subsequent to the fiducial point, determine a signal characteristic of the cardiac signal within the window, determine whether a P-wave is detected in response to the signal characteristic, determine whether an atrio-ventricular interval timer has expired, and emit a trigger signal to deliver the ventricular pacing timed off of the local maximum in response to the P-wave being detected and not timed off of the local maximum in response to the timer being expired.
