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： Techniques are described for detecting a condition of a patient using a probability-correlation based model that integrates a plurality of parameters associated with the condition. A medical device that operates in accordance with the techniques obtains a plurality of parameters associated with the condition of the patient. The medical device obtains probabilities that the condition of the patient exists based on each single parameter separately and correlations between each of the parameters and the other ones of the parameters. After obtaining the probabilities and correlations associated with each of the parameters, the medical device determines whether the condition of the patient exists based on the determined probabilities and correlations. Such techniques may be particularly effective for use in distinguishing whether a rhythm of a patient is treatable, e.g., VT or VF, or non-treatable, e.g., SVT.

摘要： A medical device and associated method for monitoring a patient's heart rhythm sense cardiac events and detect a sudden change in the heart rhythm in response to the sensed cardiac events. Detecting the sudden change includes determining a variability of intervals between the sensed cardiac events and switching between a low variability mode of operation and a high variability mode of operation in response to the variability of intervals. During the low variability mode, detecting the sudden change includes detecting an increase in the rate of cardiac events. During the high variability mode, detecting the sudden change includes detecting a sudden decrease in the variability of the cardiac event intervals. A concerning cardiac rhythm is detected in response to detecting the sudden change.

摘要： The invention is directed to method and process for discriminating supraventricular tachycardia (SVT) with 1:1 atrial to ventricular conduction (AV conduction). Upon detection of a rapid heart rate, an implanted medical device may determine whether the rhythm exhibits insufficient evidence of sinus tachycardia, whether the rhythm exhibits 1:1 conduction, and whether an electrical signal corresponding to the rhythm exhibits a normal morphology. When these tests have been satisfied, the device determines that an SVT with 1:1 AV conduction has been detected.

摘要： In a medical device that monitors and/or treats ventricular arrhythmia, the invention provides for a “normal” processing mode of operation and a “guarded” processing mode of operation. The transition between the two modes is a function of cardiac rhythm. Benign rhythms are processed in the normal processing mode and non-benign rhythms are processed in the guarded processing mode. In normal processing mode, the device performs functions that are not computationally demanding, but in guarded processing mode, the device performs the computationally demanding operations that classify arrhythmias. If therapy is deemed necessary, the device may provide the therapy in guarded processing mode.
