    摘要: A system and method provides for inhibiting delivery of atrial therapy under certain conditions. Inhibiting delivery of atrial therapy involves developing atrial intervals and ventricular intervals from sensed atrial and ventricular events, respectively. An average atrial rate and an average ventricular rate is developed from a predetermined number of the atrial and ventricular intervals, respectively. Delivery of atrial therapy is inhibited if the average atrial rate fails to exceed the average ventricular rate by at least a predetermined factor.

    摘要: A system and method for providing pacing pulses after a cardioversion/defibrillation shock, where the pacing pulses have a pacing rate at an initial value. The pacing rate is decreased from the initial value until at least one intrinsic cardiac contraction is detected. In one embodiment, the pacing rate is decreased by a set amount after pacing a set number of cardiac cycles. Providing the set number of pacing pulses and decreasing the pacing rate by the set amount is then repeated until at least one intrinsic cardiac contraction is detected. An intrinsic cardiac rate is then determined from the at least one intrinsic cardiac contraction. The pacing rate is then increased and maintained to be above (i.e., greater than) the intrinsic cardiac rate.

    摘要: A system and method provide for detecting atrial arrhythmias within an implantable medical device capable of sensing and pacing at least an atrium of a heart. Arrhythmia of the atrium is detected. In response to detecting atrial arrhythmia, delivery of pacing signals to the atrium is inhibited under certain conditions. While delivery of the pacing signals to the atrium is inhibited, the detected arrhythmia of the atrium is confirmed during a period of further evaluation. Delivery of pacing signals to the atrium is enabled upon ceasing of the atrial arrhythmia. Inhibiting delivery of the pacing signals during atrial arrhythmia evaluation advantageously provides for an increase in the rate at which the detected arrhythmia is confirmed.

    摘要: Systems and methods implemented with an implantable medical device (IMD) are provided for performing cardiac testing while temporarily disabling all or selected antitachyarrhythmia therapy delivery capabilities of the device. An initiation signal indicative of initiation of a cardiac test, such as an electrophysiologic test, is received by the IMD. In response to the test initiation signal, a capability of delivering tachyarrhythmia therapy to a chamber of the heart is temporarily disabled. While the capability of delivering tachyarrhythmia therapy is disabled, the subject heart chamber is monitored in response to electrophysiologic testing. The capability of delivering tachyarrhythmia therapy is automatically re-enabled to ensure availability of tachyarrhythmia therapy after completion or interruption of the electrophysiologic test.

    摘要: An implanted cardiac device detects an atrial arrhythmia and provides periodically updated atrial arrhythmia status as long as the arrhythmia is ongoing. A patient may request an indication of ongoing atrial arrhythmia status from external to the patient using a patient activator. The patient activator may include a magnet for closing a reed switch in the implanted device to provide the request or may provide the request over a telemetry link to the implanted device. The implanted device may provide the requested atrial arrhythmia status and other information in the form of an audible tone produced by the implanted device or as a message telemetered from the implanted device to the patient activator. The patient activator may include a tone detector and display for providing a visual indication of the atrial arrhythmia status indication. The magnet activator may also be employed to request or withhold atrial shock therapy.

    摘要: Systems and methods are provided for analyzing occurrences of atrial arrhythmias. Occurrences of each of a number of classified atrial arrhythmia rhythms are detected. The classified atrial arrhythmias may, for example, include at least atrial fibrillation and atrial flutter. A duration of time associated with each of the detected atrial arrhythmia rhythms is measured. Trend data is produced with respect to a predetermined period of time using all or selected ones of the measured time durations. The detecting, measuring, and producing processes may also be performed for one or more unclassified atrial arrhythmias.

    摘要: An apparatus and method is presented for treating patients with sinus node dysfunction who have apparently normal intrinsic AV conduction and thus do not require ventricular pacing unless there is an unexpected AV conduction failure. In one embodiment, a cardiac device with dual-chamber pacing capability is programmed to operate in a primary DDI (or DDI(R)) mode adjusted to pace only the atria if intrinsic AV conduction is intact and switch to a secondary DDD (or DDD(R)) mode upon detection of AV block.

    摘要: A system and method provides for managing atrial ATP therapy in response to possible atrial lead dislodgment. An impedance of an atrial lead is measured for a particular patient. The measured impedance is compared with an impedance threshold developed for the particular patient. Atrial ATP therapy delivery is disabled in response to the measured impedance deviating from the impedance threshold by a predetermined factor. The impedance threshold may be developed from one or more atrial lead impedance measurements, and may also be characterized by a mean or a median of several atrial lead impedance measurements. The predetermined factor may be characterized by a percentage change, a fixed delta change, or both a percentage change and a fixed delta change in the measured impedance relative to the impedance threshold.
