A system for electrocardiography includes a handheld device having a device housing, and a patient cable having a proximal end that connects to the device housing. A distal end of the patient cable breaks out into leads for attachment to a patient. The handheld device generates an electrocardiogram based on electrical signals received from the patient cable. The system further includes a docking station having a dock housing to support the device housing and to recharge a battery of the handheld device.

In one embodiment, a method to differentiate between causes of noise in an electrocardiogram (ECG) signal. The method connecting to at least one sensing electrode and obtaining the ECG signal from the at least one sensing electrode. The method also includes detecting noise on the ECG signal and detecting ancillary conditions. The method also includes associating the noise on the ECG signal with at least one of the ancillary conditions and providing an actionable indication to a patient associated with the noise on the ECG signal.

A method of determining a measure of contact of an EMG sensor with the skin of a human or animal subject, the method comprising: receiving data captured by the EMG sensor; calculating a spectral entropy of the received data over a first time period in respect of a predetermined frequency band; determining a measure of contact for the first time period in dependence on the spectral entropy of the received data; and processing the received data of the first time period in dependence on the measure of contact.

In some examples, a medical system includes one or more trialing leads implanted within a patient, one or more sensors configured to determine a value for a sensed parameter indicative of an activity level of the patient, and processing circuitry. The processing circuitry may be configured to receive the value from the one or more sensors, determine whether the value is outside a threshold range, and—in response to determining that the value is outside the threshold range—generate information indicating a status of the one or more trialing leads. In some examples, processing circuitry may be configured to output an alert warning that patient movement could dislodge, or has already dislodged, the one or more trialing leads.

A system for providing a standard electrocardiogram (ECG) signal for a human body using contactless ECG sensors for outputting to exiting medical equipment or for storage or viewing on a remote device. The system comprises a digital processing module (DPM) adapted to connect to an array of contactless ECG sensors provided in a fabric or the like. A selection mechanism is embedded into the DPM which allows the DPM to identify body parts using the ECG signals of the different ECG sensors and select for each body part the best sensor lead. The DPM may then produce the standard ECG signal using the selected ECG signals for the different body parts detected. The system is adapted to continuously re-examine the selection to ensure that the best leads are selected for a given body part following a movement of the body part, thereby, allowing for continuous and un-interrupted ECG monitoring of the patient.

The present invention relates to a medical coupling unit for electrical signal transmission between the medical coupling unit (1, 1a, 1b) and a medical sensor (2, 2a) coupled to the medical coupling unit. The medical coupling unit comprises a coupling-side connector (10) comprising a plurality of first electrical contacts (11) in or on a first surface (12) and a plurality of second electrical contacts (13) in or on a second surface (14) opposite the first surface, and a connector interface (15) for analyzing electrical signals available at one or more of the plurality of first and second electrical contacts (11, 13) to detect one or more of presence of a medical sensor coupled to the medical coupling unit, the type of medical sensor coupled to the medical coupling unit, and the orientation of a sensor-side connector of a medical sensor coupled to the medical coupling unit. The present invention relates further to a sensor-side connector (20).

Disclosed examples include those directed to detecting and remediating detachment of electrodes from a patient. In an example, a system calculates a Pearson correlation coefficient between: (1) power spectral density of the noise and (2) power spectral density of a recorded signal (e.g., from an electrode being operated in free-run EMG mode). If the recorded signal correlates with the noise, then the system notifies the user of presence of noise (e.g., the fallen electrode). Otherwise, the recorded signal is considered as the signal of interest (e.g., a valid EMG signal).

A compact integrated patch may be used to collect physiological data. The patch may be wireless. The patch may be utilized in everyday life as well as in clinical environments. Data acquired by the patch and/or external devices may be interpreted and/or be utilized by healthcare professionals and/or computer algorithms (e.g., third party applications). Data acquired by the patch may be interpreted and be presented for viewing to healthcare professionals and/or ordinary users.

A biosensor, which operates by power supplied from a battery, includes an electrode portion positioned on at least a side of one terminal of the battery; and a conductive adhesive tape having conductivity provided between the one terminal and the electrode portion. A fluctuation width of a resistance value of the conductive adhesive tape is 1.60Ω or less in absolute value when an iron ball having a weight of 33 g is dropped vertically from a height of 30 cm to apply a load to a surface of the conductive adhesive tape.
