摘要： In an example, a medical device includes a physiological data monitor (PDM), a memory, and a processor. The PDM is configured to monitor a physiological data parameter. The memory circuit is configured to store data collected by the PDM. The processor is configured to detect a data capture event and capture a first segment of physiological data associated with the data capture event. The processor is also configured to determine an amount of memory storage space available and determine a first priority level for the first segment of physiological data. The processor is further configured to determine a second priority level for a second segment of physiological data stored previously and select a processing scheme using the first and second priority levels. Finally, the processor is configured to process, using the processing scheme, the first and second segments of physiological data and store the first segment of physiological data.

摘要： A cardiac rhythm management (CRM) system includes an implantable cardioverter defibrillator (ICD) and an external system. The ICD detects a tachyarrhythmia episode and classifies the detected tachyarrhythmia episode using none, one, or more of detection enhancements selected according to a selection command including a classification mode. The detection enhancements are each an algorithm for detecting and analyzing one or more indications of a type of the detected tachyarrhythmia episode. The external system allows a user to select the classification mode from a plurality of available classification modes each using none, one, or more of the detection enhancements.

摘要： An implantable pulse generator senses a cardiac signal, identifies cardiac events in the cardiac signal, and starts a blanking interval including a repeatable noise window blanking interval in response to each cardiac event. When noise is detected during the repeatable noise window blanking interval, the noise window blanking interval is repeated. In one embodiment, the duration of repeated repeatable noise window blanking intervals is summed and compared to a pacing escape interval. When the sum is greater than the pacing escape interval, asynchronous pacing pulses are delivered until the noise ceases. Alternatively, when the sum is greater than the pacing escape interval, the pace escape interval is repeated.

摘要： A system and method for passively testing a cardiac pacemaker in which sensing signal amplitudes and lead impedance values are measured and stored while the pacemaker is functioning in its programmed mode. The amplitude and impedance data may be gotten and stored periodically at regular intervals to generate a historical record for diagnostic purposes. Sensing signal amplitudes may also be measured and stored from a sensing channel which is currently not programmed to be active as long as the pacemaker is physically configured to support the sensing channel. Such data can be useful in evaluating whether a switch in the pacemaker's operating mode is desirable.

摘要： An apparatus comprises an electrical stimulation circuit, a ventricular sensing circuit, a ventricular sensing timer, and an atrial pacing timer. The ventricular sensing circuit detects an intrinsic ventricular tachyarrhythmia depolarization. The ventricular sensing timer initiates timing of a lowest tachy rate (LTR) zone interval and also a ventricular pace interval that is calculated using a lower rate limit (LRL). The atrial pacing timer calculates an atrial pace interval to follow the intrinsic ventricular depolarization using the ventricular pace interval less a paced atrioventricular (AV) delay interval, delays generation of the atrial pace until after expiration of the LTR zone interval by decreasing the paced AV delay interval when the calculated atrial pace interval is within the LTR zone interval, and disables decreasing of the paced AV delay interval when the LRL interval less the paced AV delay interval at the LRL is less than the LTR zone interval.

摘要： A device and method for improving tachyarrhythmia detection when the ventricles are resynchronized by delivering paces to both ventricles separated by a specified offset interval. Timing of escape intervals and tachyarrhythmia detection is based upon senses from one of the ventricles designated as a rate ventricle. A reversion pacing mode is provided in order to prevent tachyarrhythmia detection from being compromised when the rate ventricle is paced after the other ventricle.

摘要： Miniature defibrillators and cardioverters detect abnormal heart rhythms and automatically apply electrical therapy to restore normal heart function. Therapy decisions are typically based on the time between successive beats of various chambers of the heart, such as the left atrium and left ventricle. To prevent confusing a left ventricle beat for a left atrium beat, some devices use cross-chamber blanking, a technique which disables sensing of atrial beats for a certain time period after sensing. Conventionally, these devices lack any mechanism for adjusting length of this period. Accordingly, the inventor devised a implantable device including a mechanism for adjusting this time period. This mechanism ultimately allows tailoring of the cross-chamber blanking period to fit the needs of individual patients.

摘要： A hybrid cardiac pacemaker in which the operation of the device is controlled by hardware-based controller as supervised by a microprocessor-based controller. The hardware-based controller comprises a plurality of timers that expire when they reach timer limit values stored in registers updatable by the microprocessor, and a combinational logic array for causing the device to generate pace outputs in accordance with timer expirations and sense signals. The combinational logic array may operate the pacemaker in a number of programmed modes in accordance with a mode value stored in a mode control register by the microprocessor.
