In a subcutaneous implantable cardioverter/defibrillator, cardiac arrhythmias are detected to determine necessary therapeutic action. Cardiac signal information is sensed from far field electrodes implanted in a patient. The sensed cardiac signal information is then amplified and filtered. Parameters such as rate, QRS pulse width, cardiac QRS slew rate, amplitude and stability measures of these parameters from the filtered cardiac signal information are measured, processed and integrated to determine if the cardioverter/defibrillator needs to initiate therapeutic action.

Apparatus and method for identifying atrial arrhythmia by far-field sensing

Non-invasive devices and systems to determine tissue wetness/hydration based on relative changes in subsurface resistivities in tissue below an electrode array applied to a human body across different frequencies. For example, these a sensor including arrays of current-injecting and voltage-sensing electrodes may be placed on a subject's back to determine lung wetness. Systems and methods for determining tissue water content, systems and methods for determining lung wetness, sensors for determining relative changes in subsurface resistivities across frequencies and systems and methods to determine which arrays of electrodes in a sensor to use to determine relative changes in subsurface resistivities across frequencies are all described.

Methods for determining the relative spatial change in subsurface resistivities across frequencies in tissue

Sensors for non-invasively determining tissue wetness/hydration based on relative changes in subsurface resistivities in tissue below the sensor when applied to a human body across different frequencies. A sensor including arrays of current-injecting and voltage-sensing electrodes may be placed on a subject's back to determine lung wetness. Sensors may be used as part of a systems and method for determining tissue water content, systems and methods for determining lung wetness, or the like. Sensors for determining relative changes in subsurface resistivities across frequencies and systems include arrays of electrodes used to determine relative changes in subsurface resistivities across frequencies may include pairs of current-injecting and voltage sensing electrodes.

Devices for determining the relative spatial change in subsurface resistivities across frequencies in tissue

A subcutaneous cardiac device includes a subcutaneous electrode and a housing coupled to the subcutaneous electrode by a lead with a lead wire. The subcutaneous electrode is adapted to be implanted in a frontal region of the patient so as to overlap a portion of the patient's heart. The subcutaneous electrode is configured for therapy delivery in combination with one or both of the housing or a second subcutaneous electrode.
