Certain aspects of the disclosure are directed to an apparatus including a scale and external circuitry. The scale includes a platform, and data-procurement circuitry for collecting signals indicative of the user's identity and cardio-physiological measurements. The scale includes processing circuitry to process data obtained by the data-procurement circuitry, therefrom generate cardio-related physiologic data, and to send user data to the external circuitry. The external circuitry identifies a risk that the user has a condition based on the reference information and the user data provided by the scale and outputs generic information correlating to the condition to the scale that is tailored based on the identified risk.

A wearable electrode includes an electrode (203) fixed to garment (21) such that the electrode (203) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper left part of the body of a wearer (20), and an electrode (204) fixed to the garment such that the electrode (204) can simultaneously come in contact with the skin of respective parts from the ventral side to the dorsal side of the upper right part of the body of the wearer (20). The electrodes (203, 204) are installed such that the attaching positions gradually descend from the ventral side to the dorsal side with the wearer (20) standing upright, or the attaching positions gradually ascend from the ventral side to the dorsal side with the wearer (20) standing upright.

An electrocardiography device is described that can include a main body, an adjustable cap, and a power switch. The main body can include an electrode of a plurality of electrodes configured to acquire electrical signal from a patient. The adjustable cap can include two electrodes of the plurality of electrodes. The adjustable cap can be rotatable around an axis on the main body to orient the plurality of electrodes on different locations on a body of the patient. The power switch can activate the plurality of electrodes to acquire the electrical signal from the patient. Related apparatuses, systems, methods, techniques and articles are also described.

A system is provided for displaying heart graphic information relating to sources and source locations of a heart disorder to assist in evaluation of the heart disorder. A heart graphic display system provides an intra-cardiogram similarity (“ICS”) graphic and a source location (“SL”) graphic. The ICS graphic includes a grid with the x-axis and y-axis representing patient cycles of a patient cardiogram with the intersections of the patient cycle identifiers indicating similarity between the patient cycles. The SL graphic provides a representation of a heart with source locations indicated. The source locations are identified based on similarity of a patient cycle to library cycles of a library cardiogram of a library of cardiograms.

In some embodiments, there are provided systems, devices, components, and corresponding methods configured to permit navigation and/or positioning of an intra-cardiac electrophysiological (EP) mapping basket or other EP mapping structure of an EP mapping catheter inside or near an atrium or other heart chamber of a patient's heart using biosignals or intra-cardiac signals. In one embodiment, QRS complexes are extracted or isolated from intra-cardiac signals sensed by electrodes mounted on the EP mapping basket. Using the QRS complexes and a statistical shape or other model of the EP mapping basket or other type of EP mapping structure, one or more computing devices then determine the locations of the electrodes inside or near the patient's atrium that are associated with each isolated or extracted QRS complex, and thereby permit accurate navigation within the heart and/or processing of data acquired using the EP mapping basket or other EP mapping structure. The one or more computing devices can also be used to determine changes in the three-dimensional locations and orientations of the basket and the electrodes thereof as the EP mapping basket is moved around, in, or near the patient's atrium, heart chamber, or other portion of the patient's heart, and to display to a user multiple positions of the basket inside or near the patient's heart.
