摘要： The invention is directed to techniques for delivering electrical stimulation to a gastrointestinal tract of a patient via an implantable stimulator and monitoring electrical activity of a patient's heart by sensing cardiac signals via electrodes coupled to the implantable stimulator. The implantable stimulator may analyze the cardiac signals and generate a cardiac therapy recommendation for the patient, or may communicate the cardiac signals via telemetry circuitry to an external device for analysis. The sensed cardiac signals may be electrocardiogram (ECG) signals.

摘要： An implantable cardiac stimulation device provides a stimulation therapy or an atrial ablation recommendation responsive to detection of atrial flutter of a heart. The device includes a sensing circuit that senses electrical activity of a heart and generates electrical signals representing electrical activity of the heart, an arrhythmia detector that detects atrial flutter of the heart, and a data processor that measures cardiac data responsive to the electrical signals. A therapy control responsive to the detection of atrial flutter recommends atrial ablation of the heart when the cardiac data satisfies a predetermined criteria and atrial flutter suppression when the cardiac data fails to satisfy the predetermined criteria. The device may further include a pulse generator that provides stimulation therapy to at least one atrium to terminate the atrial flutter.

摘要： An apparatus and method for performing multi-chamber anti-tachycardia pacing (ATP) in response to a tachycardia that is of particular use in an implantable cardiac stimulation device. The expected benefits of such a multi-chamber ATP include improved hemodynamic performance and the ability to terminate the tachycardia sooner. Embodiments of the present invention use an intrinsic chamber activation sequence and associated interchamber time delays, preferably automatically detected during a period of time when a pathologic tachycardia is not present, to treat a pathologic tachycardia should it occur. Such a device monitors two or more chambers of the patient's heart, i.e., the controlled chambers, and in the event a tachycardia is detected, the device determines the chamber which originated the tachycardia. The device then calculates anti-tachycardia pacing (ATP) cycle lengths, typically as percentages of the detected tachycardia cycle length of the chamber where the tachycardia originated, and begins pacing the controlled chambers according to the intrinsic chamber activation sequence and interchamber delays (initially synchronized relative to a cardiac signal from the chamber which originated the tachycardia) at the ATP cycle lengths for a predefined period or until the tachycardia ends. Optionally, embodiments of the present invention may additionally include a hemodynamic sensor and may adaptively alter the activation sequence and/or interchamber time delays in response to feedback from the hemodynamic sensor.

摘要： A non-invasive programming stimulation system for performing electrophysiological testing on a cardiac patient is performed using a programmer coupled to an implantable device by a communication channel. The system generates stimulating pulses for the heart and analyzes the responses to determine the pathological condition of the heart. Advantageously, before analysis, the system automatically tests for capture by the stimulating pulses to insure that the pulses do not fall into an absolute refractory period.
