摘要:
A cardiac rhythm management system that includes a pacemaker configured for biventricular pacing and an external programmer with an associated display for displaying electrogram data and markers representing ventricular events. Associated with each marker are intraventricular intervals designed to relate information to a user in a manner suited for ventricular resynchronization pacing.
摘要:
A system and method for avoiding short-interval paces during pacing mode transitions. The method may be particularly useful in switching to or from a biventricular pacing mode.
摘要:
A system and method for correlating health related data for display. The system includes a medical device recording data and a display producing device which correlates the data and simultaneously displays different types of data or displays two sets of the same type of data along with the circumstances at which the two sets of data were recorded. Such displays aid a physician in prescribing and ascertaining the efficacy of cardiac therapies.
摘要:
A medical device programmer and a method of operation in which a first data value is received and used in the execution of one or more algorithms. One or more suggested pulse generator settings are calculated from the one or more algorithms based on the first data value, and the one or more suggested pulse generator settings are displayed on an interactive display screen of the medical device programmer. In one embodiment, the first data value is a duration interval of a QRS complex. From the duration interval, suggestions are made as to one or more ventricular chambers in which to provide pacing pulses. Additionally, pacing intervals for an AV delay are suggested based on measured P-R intervals, or pacing intervals for an LV offset are suggested based on a measured duration interval of a V-V-interval between a right ventricular event and a left ventricular event.
摘要:
A system and method recording sensing and pacing events in a cardiac rhythm management device. The method may be particularly useful in assessment of pacing parameters for ventricular resynchronization therapy.

Systems, devices and methods are provided for displaying statistical distributions of cardiac events. A device embodiment comprises circuitry adapted to communicate with a medical device that is adapted to acquire data regarding cardiac events occurring at two or more cardiac sites, and display means for displaying a histogram of the data as two or more statistical distributions for the two or more cardiac sites. The histogram includes a number of histogram bins. At least one of the histogram bins includes both a representation for at least a portion of a statistical distribution of a cardiac event for a first cardiac site and a representation for at least a portion of a statistical distribution of a cardiac event for a second cardiac site. Other embodiments are provided herein.

Systems and methods provide for ambulatorily sensing pulmonary artery pressure from within a patient, and producing a pulmonary artery pressure measurement from the sensed pulmonary artery pressure. Power is ambulatorily provided within the patient to facilitate sensing of the pulmonary artery pressure and producing of the pulmonary artery pressure measurement. Acute pulmonary embolism is detected based on a change or rate of change in the pulmonary artery pressure measurement. An alert is preferably generated in response to detecting pulmonary embolism.

Disordered breathing events may be classified as central, obstructive or a combination of central an obstructive in origin based on patient motion associated with respiratory effort. Central disordered breathing is associated with disrupted respiration with reduced respiratory effort. Obstructive disordered breathing is associated with disrupted respiration accompanied by respiratory effort. A disordered breathing classification system includes a disordered breathing detector and a respiratory effort motion sensor. Components of the disordered breathing classification system may be fully or partially implantable.
摘要:
Methods and systems to modulate timing intervals for pacing therapy are described. For each cardiac cycle, one or both of an atrioventricular (A-V) timing interval and an atrial (A-A) timing interval are modulated to oppose beat-to-beat ventricular (V-V) timing variability. Pacing therapy is delivered using the modulated timing intervals.
