Various systems, methods, and devices related to modifying views of a multi-lead electrocardiogram (ECG), as well as identifying notations associated with the multi-lead ECG, are described. An example method includes displaying graphical elements in a first arrangement. The graphical elements respectively depict electrical signals indicative of an electrical activity of a heart. The example method further includes detecting a signal indicative of a display selection, and, based on the display selection, rearranging the graphical elements from the first arrangement to a second arrangement.

Systems, devices, and methods relate to utilizing an electronic caliper to analyze an electronic electrocardiogram (ECG). An example method for includes outputting, by a display, an electronic ECG within a graphical user interface (GUI). An electronic caliper is output, by the display, as overlaid on the electronic ECG within the GUI. The electronic caliper includes a first electronic tip and a second electronic tip. The method further includes receiving, by a user input device, a user input signal and moving, based on the user input signal, the first electronic tip, the second electronic tip, or both the first electronic tip and the second electronic tip, relative to the electronic ECG within the GUI.

A defibrillation device for administering an electrotherapy, such as a dual-sequential defibrillation (DSD) electrotherapy. The defibrillation device can include a defibrillation therapy module, a physiological parameter module and a control module. The defibrillation therapy module can output one or more energies and the physiological parameter module can receive one or more physiological parameters, including electrocardiogram (ECG) data. The control module can analyze the physiological parameters to determine an indication for the administration of an electrotherapy and can determine a DSD electrotherapy. The DSD electrotherapy can be based at least in part on the physiological parameters, the indication for the administration of an electrotherapy or a review of the ECG data.

Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient's skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.

A wearable medical device includes a garment and a medical device. The medical device has a functionality that can transition between an operative state and an inoperative state. When the functionality is in the inoperative state, a protrusion extends so as to poke the patient, as an indication that steps need to be taken to make the device ready for use.

RFID-based sensors, RFID readers and software sense a changed condition. In one embodiment, an RFID-based sensor includes a base that may be placed at a location where a condition may change. The sensor includes an RFID tag that is coupled to the base. The sensor also includes a detector that can be electrically coupled to the RFID tag. If the condition changes, an electrical property of the detector also changes, impacting an operation of the RFID tag. The impacted operation can be detected by an RFID reader/interrogator so as to provide a notification. An advantage over the prior art is that the condition change can be sensed wirelessly over a domain that can be laborious or hazardous to access otherwise. Moreover, RFID based sensors can be made by modifying common RFID tags.

A portable medical device having a reliable readiness indicator. Embodiments provide a reliable readiness indicator with an active clasp that holds the garment in place. The clasp is enabled by the defibrillator when it is ready for use. If the clasp is not enabled the garment cannot be worn comfortably, and it becomes apparent to the patient that steps need to be taken to make the device ready for use.

An illustrative method and system for displaying ECG data of a patient includes the steps of: receiving an ECG waveform of a patient, determining at least a first attribute of the ECG waveform, and determining at least one data point from the first attribute of the ECG waveform. The first data point and associated first attribute of the ECG waveform are displayed on a linear scale. In an alternative method, the at least one data point is structured in a database of ECG data according to the Cabrera sequence; the display domain of the display is divided into several recurrent display slots; and a sequential one of the several recurrent display slots is associated with the at least one data point, which is displayed on the linear scale in the order in which the at least one data point appears in the Cabrera structured database of ECG data.

Linear display of ECG signals

A wearable defibrillation system can establish a local comlink with a mobile communication device, such as a smartphone, tablet-type computer and the like. The mobile communication device can in turn establish a remote comlink with other devices in a network such as the internet. Accordingly, communication tasks relating to the wearable defibrillation system can be performed via the local and the remote comlinks, with or without the participation of the patient, who is wearing the system. The wearer can thus use the familiar interface of a mobile communication device for interacting with his defibrillator system. Moreover, he can do so while keeping on his regular clothes, which could conceal completely the wearable defibrillator system. The patient can thus preserve his dignity and privacy.
