A medical data management system is provided that facilitates expedited review of health data for patient care. The medical data management system includes devices for collecting the health data, associating the health data with health events, optimizing storage of health data, and displaying comprehensive patient data for efficient and rapid review. The system includes a medical monitoring device that uses sensors to acquire health data and logic to specify data blocks of the data that characterize health episodes. Data management device(s) stitch the data blocks according to timelines and store the stitched data blocks as a full episode. The stitched data blocks are rendered for display, as a data presentation with timelines and graphic representations.

Health data management and display

A Wearable Medical System (WMS) includes one or more pacing capabilities. The WMS may detect when the patient's heart rhythm starts to deteriorate, but not necessarily in a way that requires defibrillation. In particular, the WMS may detect bradycardia of one or more types, and then confirm the detection before pacing to treat the detected bradycardia.

Rhythm sensing during external pacing

A wearable medical device comprising monitoring circuitry to monitor one or more patient parameters of a patient and defibrillation circuitry to provide one or more defibrillation shocks to the patient responsive to a control signal from the monitoring circuitry. The defibrillation circuitry comprises a defibrillation capacitor to provide energy for the one or more defibrillation shocks. The wearable medical device also comprises a power source to provide power to the monitoring circuitry and the defibrillation circuitry. The power source comprises a low current power source (LCPS) to provide power to the monitoring circuitry, and a high current power source (HCPS) to provide power to the defibrillation circuitry.

Power in a wearable cardioverter defibrillator (WCD)

Technologies and implementations for a wearable healthcare system including an information management module (IMM). The IMM may be configured to detect proximity of a healthcare device. The IMM may be configured to determine a type of the detected healthcare device. Once the type of healthcare device is determined, the IMM may be configured to communicate information regarding a medical device, where the communicated information may be adapted to correspond to the determined type of healthcare device.

Providing wearable device information to rescuers

Disclosed are embodiments directed to security methods applied to connections between components in a distributed (networked) system including medical and non-medical devices, providing secure authentication, authorization, patient and device data transfer, and patient data association and privacy for components of the system.

Permission-based control of interfacing components with a medical device

In one embodiment, a WCD is described. The WCD includes a support structure configured to be worn by a patient and a processor coupled to the support structure. The WCD also includes an energy storage module configured to store an electrical charge and in communication with the processor. The WCD also includes a discharge circuit coupled to the energy storage module, the discharge circuit in communication with the processor and configured to discharge the stored electrical charge through a body of the patient. The processor is configured to detect an event at the WCD, classify the detected event, and determine an alarm onset time of the detected event based at least in part on the event classification. The processor is further configured to issue the alarm after the alarm onset time.

WCD system alert issuance and resolution

A wearable cardioverter defibrillator (WCD) system includes a support structure that the patient may wear, and one or more sensors that may acquire patient physiological signals, such as ECG and others. A processor of the WCD system may determine diagnostics from the patient physiological signals. These diagnostics include a six-second ECG portion, heart rates as histograms, heart rates against QRS width, heart rate trends, clinical event counters, diagnostics relating to heart rate variability and about the atrial arrhythmia burden of the patient. In some embodiments, the WCD system includes a user interface with a screen that displays these diagnostics. In some embodiments, the WCD system exports these diagnostics for viewing by a different screen. When viewed, these diagnostics permit more detailed analysis of the state of the patient.

In embodiments, a Wearable Cardiac Defibrillator (WCD) system is configured to be worn by an ambulatory patient. The WCD system includes a main user interface (UI) output device that can output an image, sound or vibration as a main message about a condition of the patient or the WCD system. The patient may further carry a peripheral device that can also output an image, sound or vibration as a peripheral message about the condition. The peripheral message may mirror the main message at least in part, amplify it, and so on. The availability of the peripheral message provides the patient with the opportunity to better perceive the main message, and the flexibility to receive and react to it discreetly, learn more about the condition, and so on.

Wearable cardioverter defibrillator (WCD) system having main UI that conveys message and peripheral device that amplifies the message

A wearable cardioverter defibrillator (WCD) comprises a plurality of electrocardiography (ECG) electrodes. An episode is opened responsive to a string of consecutive segments meeting one or more shock criteria, and a shockable rhythm is confirmed for the episode responsive to a subsequent string of consecutive segments meeting one or more confirmation criteria.

Wearable cardioverter defibrillator (WCD) segment based episode opening and confirmation periods

A wearable cardioverter defibrillator (WCD) having a processor configured to receive a signal indicating a position and/or movement of the ambulatory patient while the ambulatory patient is wearing the support structure receive the ECG signal, determine from an ECG signal whether a shock criterion is met, determine a confirmation time period and/or a response time period based on the position and/or movement of the ambulatory patient, determine from the ECG signal whether the shock criterion is met after the confirmation time period has elapsed, cause the user interface to generate the shock alert signal based on the shock criterion determined after the confirmation time period has elapsed, and control the discharge circuit to discharge the stored electrical charge when a predetermined time period has elapsed after the shock alert signal.

Wearable cardioverter defibrillator having adjustable alarm time

A WCD system is configured to monitor various characteristics of the WCD system including about the patient. The WCD system is further configured to transmit a notification of a notifiable event to responders that are outside a local area of the patient, and to silence the notification for any responder(s) that are inside the local area of the patient.

Wearable cardioverter defibrillator system with remote alerts based on proximity

In embodiments, a wearable medical system (WMS) for an ambulatory patient, which can be a wearable cardioverter defibrillator (WCD) system, analyzes the patient's ECG signal to generate a detection outcome. The WMS also has an ambulatory user interface that outputs a human-visible indication. A programming device, such as a PC, a tablet, etc., establishes a communication link with the WMS during an in-person session with the patient. The programming device may include a programming screen that reproduces the human-visible indication in real time. An advantage can be that the person programming the WMS need not strain to look also at the ambulatory user interface at the time they are looking at the programming device. Another advantage can be that the patient will recognize that he or she is better protected, and have their confidence in the WMS increased, and therefore better comply with wearing the WMS as required.
