摘要： An implantable medical device system and associated method select subcutaneous sensing electrodes for use in monitoring the heart rhythm. A subset of multiple sensing vectors is selected from a number of electrodes positioned at a first subcutaneous location and one electrode positioned at a second subcutaneous location. The subset of sensing vectors includes one vector that includes the electrode positioned at the second location. A signal quality parameter corresponding to each of the sensing vectors of the subset is determined.

摘要： Techniques for determining whether artifacts are present in a cardiac electrogram are described. According to one example, a medical device senses a cardiac electrogram via electrodes. The medical device determines a derivative, e.g., a second order derivative, the electrogram. The medical device detects beats within the derivative, e.g., by comparing a rectified version of the derivative to one or more thresholds determined based on a maximum of the rectified derivative. The medical device determines whether the beats are periodic, and determines whether artifacts are present in the cardiac electrogram based on the determination of whether the beats are periodic. The medical device may further determine whether tachyarrhythmia is present and/or whether the cardiac rhythm of the patient is treatable based on the determination of whether the beats are periodic. For example, the medical device may determine that an electrogram is not treatable when the beats are periodic.

摘要： An implantable medical device (IMD) for gauging the severity of ischemia in a patient's heart includes a data collection module configured to receive data about the patient's heart, a data processing module configured to process the data to identify an episode of ischemia in the patient and to determine if the episode is stable or unstable, and a reporting module configured to provide an alarm to the patient if the episode is unstable. A method executable by an implantable medical device to detect ischemia in a human heart suitably includes the steps of receiving data about the heart at the implantable medical device, processing the data within the implantable medical device to determine the severity of ischemia, and providing a response from the implantable medical device to the patient if ischemia is indicated.

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.

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.
