Abstract

Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch with sewn electrodes and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

Dependent claims

An extended wear sewn electrode electrocardiography monitor, comprising:

an extended wear electrocardiography patch, comprising:
a flexible backing formed of an elongated strip of stretchable material with narrow longitudinal midsection evenly tapering inward from a distal end and a proximal end, the elongated strip adherable only to a contact surface defined on each of the ends;
a pair of flexile wires, one of the wires forming an electrocardiographic electrode, the electrocardiographic electrode formed by a portion of the one wire that is sewn into the distal end of the elongated strip and that is configured for directly contacting the patient, the one wire continuing back along an axial path through the midsection, another one of the wires forming another electrocardiographic electrode, the another electrocardiographic electrode formed by a portion of the another wire that is sewn into the proximal end of the elongated strip and that is configured for electrically contacting the patient, each of the electrodes comprising an electrically conductive area only exposed on the contact surface;
and
a circuit board affixed on one of the ends of the elongated strip and connected to both of the flexile wires and comprising one or more electrical contact mating pads operable to electrically couple an electrocardiography monitor with the pair of the electrodes.
