    摘要： An implantable medical device acquires a first cardiac signal in a first heart chamber and a second cardiac signal in a second heart chamber. The device determines if the first signal is unreliable. In response to determining the first signal to be unreliable, the device switches from a first cardiac arrhythmia detection mode of operation to a second cardiac arrhythmia detection mode of operation, the first detection mode requiring the use of both the first cardiac signal and the second cardiac signal and the second detection mode requiring the use of the second cardiac signal and not requiring the use of the first cardiac signal.

    摘要： A method and apparatus for monitoring a patient's heart rate sense first cardiac events in a heart chamber using a first cardiac electrode pair and sense second cardiac events in the heart chamber using a second cardiac electrode pair. The method includes estimating a first heart rate using the first cardiac events, comparing the first heart rate to a heart rate threshold and estimating a second heart rate using the second cardiac events in response to the first heart rate exceeding the heart rate threshold, determining whether the second cardiac events are unreliable, and setting the second heart rate equal to the first heart rate in response to the second cardiac events being unreliable.

    摘要： A medical device and associated method control the delivery of a cardiac pacing therapy including selecting left ventricular pacing sites for delivering the therapy. The left ventricular pacing sites are selected by delivering pacing pulses to a patient's left ventricle at multiple pacing sites one at a time and determining right ventricular activation times in response to the pacing pulses being delivered at each of the pacing sites. A left ventricular pacing site is selected in response to the determined right ventricular activation times.

    摘要： In some examples, an IMD provides CRT data that indicates an amount of time that CRT was not delivered by the IMD, such as the % CRT. In some examples, a CRT loss diagnosis module apportions the amount of time that CRT was not delivered amongst predetermined reasons for loss of CRT based on the CRT data and sensed cardiac data from the IMD. An external computing device may present a representation of the apportionment to a user, e.g., a clinician. The external computing device may also analyze the apportionment, and recommend programming changes for the delivery of CRT by the IMD based on the analysis.

    摘要： Techniques for evaluating cardiac electrical dyssynchrony are described. In some examples, an activation time is determined for each of a plurality of torso-surface potential signals. The dispersion or sequence of these activation times may be analyzed or presented to provide variety of indications of the electrical dyssynchrony of the heart of the patient. In some examples, the locations of the electrodes of the set of electrodes, and thus the locations at which the torso-surface potential signals were sensed, may be projected on the surface of a model torso that includes a model heart. The inverse problem of electrocardiography may be solved to determine electrical activation times for regions of the model heart based on the torso-surface potential signals sensed from the patient.
