Systems and methods are provided for an electrocardiograph system. A set of electrodes is configured to detect a voltage differences between various pairs of locations on a body of a patient. A display is configured to visually represent digital signals derived from the plurality of detected voltage differences. A display interface is configured to format the digital signals for the display, such that the leads are grouped and displayed as a sequence of proper subsets or groups of the plurality of detected voltage differences. Each proper subset or lead group represents a specific anatomical structure of a heart of the patient.

Systems, methods and devices for providing combined ultrasound, electrocardiography, and auscultation data are provided. One such system includes an ultrasound sensor, an electrocardiogram (EKG) sensor, an auscultation sensor, and a computing device. The computing device includes memory and a processor, and the processor receives signals from the ultrasound sensor, the EKG sensor, and the auscultation sensor. Artificial intelligence techniques may be employed for automatically analyzing the data obtained from the ultrasound sensor, the EKG sensor, and the auscultation sensor and producing a clinically-relevant determination based on a combined analysis of the data.

A system (100) for assessing fluid responsiveness includes an infusion pump (24) in communication with at least one processor (32), and a plurality of physiological monitors (40,42,44,46) operable to receive physiological signals from an associated patient. Physiological signals (48,50) acquired from the associated patient (10) during a fluid challenge are synchronized with a timing signal (54) of the infusion pump (24) administering the fluid challenge. One or more dynamic indices and/or features (58) is calculated from the synchronized physiological signals (50), and one or more dynamic indices and/or features (50) is calculated from baseline physiological signals (48) acquired from the associated patient (10) prior to the fluid challenge. A fluid responsiveness probability value (64) of the patient (10) is determined based on dynamic indices and/or features (58) from the synchronized physiological signals (50) and dynamic indices and/or features (50) from the baseline physiological signals (48).

A method includes receiving an anatomical map of at least a portion of a heart. Positions and respective bipolar intracardiac electrogram (EGM) signals measured at the positions are received for at least a region of the anatomical map. Primary activations and secondary activations are identified in the bipolar intracardiac EGM signals. A surface representation of the bipolar intracardiac EGM signals over the region is derived, including the identified primary activations and secondary activations. The surface representation is presented overlaid on the anatomical map.

Systems, methods and devices for reducing noise in health monitoring including monitoring systems, methods and/or devices receiving a health signal and/or having at least one electrode or sensor for health monitoring.

An excitement propagation visualization apparatus detects an excitement propagation wave front for each analysis time on the basis of excitement propagation data indicative of a potential generated by excitement propagation. Next, the excitement propagation visualization apparatus detects for each analysis time an intersection of a straight line passing through a first point inside a heart and a second point outside the heart and the excitement propagation wave front. Furthermore, the excitement propagation visualization apparatus generates for each analysis time a display object associated with the intersection of the straight line and the excitement propagation wave front. In addition, the excitement propagation visualization apparatus draws the display object generated for each analysis time at a position of the associated intersection in a drawing area indicative of an analysis space.

Technologies and implementations for wearable healthcare devices are generally disclosed. An example method performed by a wrist-wearable device includes: detecting, by a sensor, a physiological parameter of a user; determining, by a processor based on the physiological parameter, that the user is experiencing atrial fibrillation (AF); outputting, by a display, a visual signal indicating that the user is experiencing the AF; and transmitting, by a transceiver to a first external computing device, a first wireless signal indicating that the user experienced the AF.

Techniques for determining whether a ventricular depolarization is a premature ventricular contraction (PVC) depolarization may include processing circuitry of a medical system identifying an interval from a maximum slope point to a minimum slope point for each of a plurality of ventricular depolarizations and, for each of the plurality of ventricular depolarizations as a current ventricular depolarization, determining that the intervals from the maximum slope point to the minimum slope point for the current ventricular depolarization, a preceding adjacent ventricular depolarization of the plurality of ventricular depolarizations, and a subsequent adjacent ventricular depolarization of the plurality of ventricular depolarizations satisfy one or more slope criteria. The processing circuitry determines that the current ventricular depolarization is a PVC depolarization based on the intervals from the maximum slope point to the minimum slope point satisfying the one or more slope criteria.

A system for processing cardiac activation information associated with a complex rhythm disorder identifies a location of the heart rhythm disorder by determining activations within cardiac signals obtained at neighboring locations of the heart and arranging the activations to identify an activation trail. The activation trail may define a rotational pattern or radially emanating pattern corresponding to an approximate core of the heart rhythm disorder.

In the present invention, a system that has a navigation signal delivered by one of a signal or navigation catheter or treatment catheter as directed by a controller for detection by the other of the navigation catheter or the a treatment catheter to navigate the treatment catheter to a specific point or area of interest using the detected navigation signal is provided. The system is operable in a method to perform the above utilizing the mapping function of the electrophysiology mapping and/or recorder system to energize electrodes on either the navigation catheter or treatment catheter to direct the treatment catheter to the area, region or point of interest.
