Non-invasive cardiac monitor and methods of using continuously recorded cardiac data
First Claim
1. A continuous cardiac monitor, comprising:
- a watertight housing;
a surface on the housing configured to be sealably engaged to a mammal;
an adhesive on the surface configured to remain continuously affixed to the mammal for at least 7 days, without removal until completion of monitoring;
at least two electrodes permanently disposed within the housing, positioned to detect continuous cardiac rhythm information of the mammal while the surface is sealably engaged to the mammal, wherein a distance between a center of one of the electrodes and a center of another of the electrodes is at least about 5 cm;
an action sequencer circuit within the housing and coupled with the at least two electrodes, the action sequencer circuit having no central processing unit for rhythm analysis and having an electronic memory configured to store all of the continuous cardiac rhythm information for the at least 7 days, the continuous cardiac rhythm information comprising both normal cardiac rhythm information and abnormal cardiac rhythm information; and
electrical connections within the housing connecting the electronic memory to the at least two electrodes throughout the at least 7 days,wherein the watertight housing allows the mammal to bathe and otherwise expose the cardiac monitor to water without requiring removal of the monitor during the at least 7 days and thus provides for the detecting and storing of continuous cardiac rhythm information by the monitor throughout the at least 7 days thereby allowing for a more complete assessment of all normal and abnormal cardiac rhythms and their total durations during the at least 7 days, based on continuous, uninterrupted cardiac rhythm information stored by the monitor.

Abstract
One embodiment of the invention is a cardiac monitor having a housing; a plurality of electrodes within and extending from the housing; a state machine within the housing configured to digitialize and store in memory signals from the plurality of electrodes; a sealing surface and an adhesive on the sealing surface configured to form a watertight perimeter around the plurality of electrodes when the housing is affixed to a mammal. Another embodiment of the invention provides a continuous cardiac monitor having a housing; a surface on the housing adapted to be sealably engaged to a mammal; an adhesive on the surface that is adapted to remain affixed to the mammal for at least 7 days; at least two electrodes within the housing positioned to detect a cardiac information of the mammal while the surface is sealably engaged to the mammal; an electronic memory within the housing wherein, the electronic memory is sized to store at least 24 hours of continuous cardiac information; and wiring within the housing connecting the electronic memory to the electrodes.

22. A continuous cardiac monitor, comprising:
-
a watertight housing; a surface on the housing adapted to be sealably engaged to a mammal; an adhesive on the surface configured to remain continuously affixed to the mammal for at least 7 days, without removal until completion of monitoring; a rim extending from a central portion of the housing to form a watertight electrode chamber when the surface is affixed to the mammal; first and second electrodes permanently disposed within the housing and positioned to detect continuous cardiac rhythm information of the mammal while the surface is sealably engaged to the mammal, wherein a distance between a center of the first electrode and a center of the second electrode is at least about 5 cm, and wherein the first and second electrodes are positioned within the watertight electrode chamber; an action sequencer circuit within the housing having no central processing unit for rhythm analysis, wherein the action sequencer circuit operates to store the continuous cardiac rhythm information detected by the at least two electrodes into an electronic memory without determining whether the continuous cardiac rhythm information corresponds to a normal cardiac rhythm or an abnormal cardiac rhythm; and electrical connections within the housing connecting the electronic memory to the at least two electrodes throughout the at least 7 days, wherein the watertight housing allows the mammal to bathe and otherwise expose the cardiac monitor to water without requiring removal of the monitor during the at least 7 days and thus provides for the detecting and storing of continuous cardiac rhythm information by the monitor throughout the at least 7 days, thereby allowing for a more complete assessment of all normal and abnormal cardiac rhythms and their total durations during the at least 7 days, based on continuous, uninterrupted cardiac rhythm information stored by the monitor. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
