摘要： A method and system for the detection of electromagnetic interference is disclosed in which a telemetry coil or other magnetic sensor is used to detect a magnetic signal. If a magnetic signal is determined to be a non-telemetry signal and is time-correlated with the onset of an increase in heart rate, electromagnetic interference is assumed to be present.

摘要： A self-diagnostic system for an implantable cardiac device such as a pacemaker, cardioverter, or resynchronization device which utilizes a subcutaneous ECG channel is described. The subcutaneous ECG channel allows the device to, in real time and independent of the standard pacing and sensing circuitry, verify the presence of pacing spikes, chamber senses, and other device outputs and hence establish and verify device integrity.

摘要： Systems and methods of managing features or functions of an implantable cardiac device involve forming a baseline evoked response template prior to delivery of defibrillation therapy to a patient's heart, and acquiring a post-shock evoked response signal subsequent to defibrillation therapy delivery. The baseline evoked response template is compared to the post-shock evoked response signal. A determination is made whether to enable, disable or adjust a cardiac device feature based on the comparison. The cardiac device feature may be a therapy feature, a monitoring feature, or a diagnostic feature.

摘要： A CRM system enhances intracardiac electrogram-based arrhythmia detection using a wireless electrocardiogram (ECG), which is a signal sensed with implantable electrodes and approximating a surface ECG. In one embodiment, an intracardiac electrogram allows for detection of an arrhythmia, and the wireless ECG allows for classification of the detected arrhythmia by locating its origin. In another embodiment, the wireless ECG is sensed as a substitute signal for the intracardiac electrogram when the sensing of the intracardiac electrogram becomes unreliable. In another embodiment, a cardiac signal needed for a particular purpose is selected from one or more intracardiac electrograms and one or more wireless ECGs based on a desirable signal quality. In another embodiment, intracardiac electrogram-based arrhythmia detection and wireless ECG-based arrhythmia detection confirm with each other before indicating a detection of arrhythmia of a certain type.

摘要： An implantable medical device includes a radio-frequency (RF) telemetry circuit and a power connection module through which the RF telemetry circuit is connected to an energy source such as a battery. The power connection module connects power from the energy source to at least one portion of the RF telemetry circuit when a user initiates an RF telemetry session. After the RF telemetry session is completed, the power connection module shuts off the at least one portion of the RF telemetry circuit. Power-on examples include a wireless telemetry activation signal received by a low power radio receiver in the implantable device, a physical motion detected by an activity sensor in the implantable device, an activation of an inductive telemetry circuit in the implantable device, a magnetic field detected by a magnetic field detector in the implantable device, and/or a telemetry activation signal detected by a sensing circuit included in the implantable device. Power-off examples include a wireless termination signal received by the implantable device, a delay timeout following the RF telemetry session, and/or a signal received by an inductive telemetry circuit in the implantable device.

摘要： A voltage sensing system includes input impedance balancing for electrocardiogram (ECG) sensing or other applications, providing immunity to common-mode noise signals while capable of use with two electrodes. Signals are received at first and second electrodes having associated impedances. An impedance circuit includes a feedback controller that adjusts an effective impedance associated with the second electrode based on a difference signal, a common mode signal, a phase-shifted (e.g., quadrature common mode) signal, and an impedance associated with the first electrode. As a result, signals associated with each electrode undergo a similar degree of gain/attenuation and/or phase-shift. This reduces common mode noise and enhances the signal-to-noise characteristics of a desired ECG or other output signal, without requiring the use of more than two electrodes.

摘要： To enhance the ability to visualize P-waves in surface ECG data, an algorithm is presented in which the ECG data is selectively passed through first and second signal processing channels where one of the channels includes signal processing elements for enhancing P-waves and the other channel provides a delayed version of the original data. Upon detection of an atrial pace event, the filtered or filtered and amplified data is inserted into the data stream in place of the raw input signal for a predetermined time interval sufficiently long to ensure the occurrence of an atrial depolarization signal.

摘要： A system and method for detecting pacing pulses generated by a cardiac pacemaker within an ECG signal. The method involves decomposing the ECG signal into high and low-frequency components that represent the energy of the input signal in high and low-frequency bands. The timing of energy pulses detected within the high and low-frequency bands are then used to determine whether the pulses may represent a pacing pulse.
