US 2015/0087923 A1 · Event Alerting Through Actigraphy Embedded Within Electrocardiographic Data

Abstract

Physiological monitoring can be provided through an actigraphy sensor imbedded into an electrocardiography monitor, which correlates movement and electrocardiographic data. Physiological monitoring can be provided through a wearable monitor that includes two components, a flexible extended wear electrode patch and a removable reusable monitor recorder. The wearable monitor sits centrally on the patient's chest along the sternum. The patient can place an electrode patch anywhere within the general region of the sternum. The occurrence of actigraphy events are monitored by the monitor recorder through an actigraphy sensor. Actigraphy becomes a recordable actigraphy event occurrence when the movement of the wearable monitor and, therefore, the patient, exceeds a certain criteria threshold of acceleration or deceleration as detected by the actigraphy sensor. Certain actigraphy event occurrences as recorded by the monitor recorder are considered to be actionable, that is, of sufficient importance to warrant flagging for further consideration to a following physician.

Dependent claims

An extended wear electrocardiography and physiological sensor monitor recorder, comprising:

a sealed housing adapted to be removably secured into the non-conductive receptacle on a disposable extended wear electrode patch;
and
an electronic circuitry comprised within the sealed housing, comprising:
an externally-powered micro-controller operable to execute under micro programmable control;
an electrocardiographic front end circuit electrically interfaced to the micro-controller and operable to sense electrocardiographic signals through electrocardiographic electrodes provided on the disposable extended wear electrode patch, each of the electrocardiographic electrodes adapted to be positioned axially along the midline of the sternum for capturing action potential propagation;
an actigraphy sensor electrically interfaced with the micro-controller and operable to sense actigraphy event occurrences based on movement of the sealed housing using an actigraphy event occurrence criteria;
and
an externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and samples of the actigraphy event occurrences.

and
a reusable electrocardiography monitor having a sealed housing adapted to be removably secured into the non-conductive receptacle and comprising:
a micro-controller operable to execute under micro programmable control and electrically interfaced to an electrocardiographic front end circuit that is operable to sense electrocardiographic signals through the electrocardiographic electrodes via the pair of the electrical pads;
an actigraphy sensor electrically interfaced with the micro-controller and operable to sense actigraphy event occurrences based on movement of the sealed housing using an actigraphy event occurrence criteria;
and
flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and samples of actigraphy event occurrences detected by the actigraphy sensor.
