The device includes a cardiac therapy circuit with a first terminal, and a peripheral therapy circuit with a second terminal. These terminals can either receive a cardiac detection/stimulation lead and a peripheral detection/stimulation lead of an anatomical structure. The device is configured to recognize the leads and automatically configure the connection terminals. This includes discrimination methods for identifying the terminal on which a cardiac signal is detected, and switching methods for coupling the cardiac therapy circuit to the terminal and the peripheral therapy circuit to the other terminal.

A bio-information analysis device includes a measuring unit that measures biometric waveforms of a subject, and a calculating unit that calculates a matching rate of the biometric waveforms based on shapes and magnitudes of the biometric waveforms measured by the measuring unit. In the bio-information analysis device, the biometric waveforms may be electrocardiogram waveforms.

Medical devices are provided, comprising a medical device and a sensor.

A medical device and associated method for detecting and treating tachyarrhythmias acquires a cardiac signal using electrodes coupled to a sensing module. During an initial detection process, a shockable cardiac rhythm is detected by a processing module configured to compare the cardiac signal to a first set of detection criteria. By analyzing the cardiac signal, the processing module establishes at least one patient-specific detection threshold during the initial detection process. Upon establishing the at least one patient-specific detection threshold, the initial detection process is stopped, and a next detection process is started which includes comparing the cardiac signal to a second set of detection criteria including the at least one patient-specific detection threshold. In some embodiments, user programming of tachyarrhythmia detection parameters is not required.

Systems, methods, and graphical user interfaces are described herein for non-invasively detecting phrenic nerve stimulation during cardiac pacing therapy. Phrenic nerve stimulation information may be generated for one or more electrical pacing vectors at one or more power configurations. The phrenic nerve stimulation information may be displayed to a user for use in configuring and/or evaluating cardiac pacing therapy.

There is described a technique using apparatus for recording and analyzing a surface electrocardiogram (ECG) for distinguishing a physiological signal from noise. The technique involves aligning and averaging multiple surface electrogram records taken for repeated pacing sequence with the same interval between pacing stimuli.

Methods, implantable medical devices and systems configured to perform analysis of captured signals from implanted electrodes to identify cardiac arrhythmias. In an illustrative embodiment, signals captured from two or more sensing vectors are analyzed, where the signals are captured with a patient in at least first and second body positions. Analysis is performed to identify primary or default sensing vectors and/or templates for event detection.

Diagnostic apparatus (24) includes a sealed case (40), including a biocompatible material and configured for implantation within a body of a human subject (22). At least one antenna (42) is configured to be implanted in the body in proximity to a target tissue (28) and to receive radio frequency (RF) electromagnetic waves propagated through the target tissue and to output a signal in response to the received waves. Processing circuitry (44,46), which is contained within the case, us coupled to receive and process the signal from the antenna so as to derive and output an indication of a characteristic of the target tissue.

Systems and methods for detecting a target physiologic event and storing physiologic information associated with the detected physiologic event are disclosed. A system can receive a physiologic signal obtained from a subject, and detect the target physiologic event using a first portion of the received physiologic signal. The system can confirm the target physiologic event using a second portion of the received physiologic signal. If the target physiologic event is confirmed, the system can store physiologic information associated with the confirmed target physiologic event in a memory.

An intracardiac pacemaker device, comprising a housing that is configured to be implanted entirely within a ventricle (V) of a heart (H), an electronic module for generating pacing pulses, a battery for supplying energy to the electronic module, an elongated lead extension protruding from the housing, at least a first electrode arranged on the elongated lead extension, and a pacing electrode and a return electrode for applying the pacing pulses to cardiac tissue, wherein the pacing electrode is arranged on the housing. The electronic module is electrically coupled to the pacing electrode via the housing, and wherein the electronic module is configured to carry out measurements of electrical activity via the at least one first electrode of the elongated lead extension.
