The electrophysiology and location information can be used to generate the electrophysiology map, such as a local activation time, peak-to-peak voltage, or fractionation map. Animated timing markers can be superimposed upon the electrophysiology map using the electrophysiology, location, and timing information. For example a series of frames can be displayed sequentially, each including a static image of the electrophysiology map at a point in time and timing markers corresponding to the state or position of an activation wavefront at the point in time superimposed thereon. The visibility or opacity of the timing markers can be adjusted from frame to frame, dependent upon a distance between the timing marker and the activation wavefront, to give the illusion that the timing markers are moving along the electrophysiology map.

A medical device monitors a primary diagnostic parameter that is indicative of worsening heart failure, such as intrathoracic impedance or pressure, and one or more secondary diagnostic parameters. The medical device detects worsening heart failure in the patient based on the primary diagnostic parameter when an index that is changed over time based on the primary diagnostic parameter value is outside a range of values, termed the threshold zone. When the index is within the threshold zone, the medical device detects worsening heart failure in the patient based on the one or more secondary diagnostic parameters. Upon detecting worsening heart failure, the medical device may, for example, provide an alert that enables the patient to seek medical attention before experiencing a heart failure event.

    Abstract: A system and method for classifying body activities through an on-body antenna measuring changes in reflected power and the resulting reflection coefficients, in contrast to two antenna systems that measure transmission power therebetween. A single on-body antenna can be attached or held in close proximity to the body. The antenna can be calibrated based on changes in the reflection coefficients for various calibration activities for the location at which the antenna is placed on the body. Magnitude changes and patterns of the reflection coefficients at a given frequency for a given activity can be compared with calibrated data to correlate a given activity. Further accuracy can be gained by comparing both magnitude and phase changes and patterns at a given frequency with calibrated data for a given activity. The antenna can use power losses from a transmitted signal to measure the changes in the reflected power to minimize power requirements.

    Abstract: A breath sensor includes a base body, a first electrode provided on a part of a surface of the base body, a second electrode provided on a part of the surface of the base body, and a covering layer made of a material that does not pass moisture therethrough, the covering layer covering the second electrode with the base body. The base body is preferably made of a material whose surface potential changes due to attachment of moisture to one of a surface of the first electrode and the surface of the base body. A surface potential on a side of the first electrode of the base body changes when a breath containing moisture touches the surface of the first electrode.
