In embodiments, a wearable cardioverter defibrillator (WCD) system includes a support structure for wearing by an ambulatory patient. When worn, the support structure maintains electrodes on the patient's body. Different pairs of these electrodes define different channels, and different patient ECG signals can be sensed from the channels. The ECG signals can be analyzed to determine which one is the best to use, for the WCD system to make a shock/no shock decision. The analysis can be according to widths of the QRS complexes, consistency of the QRS complexes, or heart rate agreement statistics.

A physiological information acquisition device includes: a reception interface configured to receive waveform data corresponding to a measured waveform of a physiological parameter of a subject from a sensor; a notifier configured to output an alarm indicating that the physiological parameter is not normally acquired; a processor configured to cause the notifier to output the alarm based on the waveform data; and a predictor configured to predict, based on the waveform data, a probability that the physiological parameter is erroneously calculated. The processor is configured to cause the notifier to perform a notification of at least one of a quality of the waveform data, a state of the sensor, and an action shall be taken by a user, based on the probability.

A method of operating a personal safety system including a vehicle includes automatically detecting that a smartphone is within a communication range using a wireless communication system of the vehicle, and starting an approach time period with a controller of the vehicle or the smartphone when the smartphone is detected. The method further includes sending checkup data from the vehicle to the smartphone using the wireless communication system when the smartphone fails to arrive at the vehicle prior to the approach time period elapsing, and triggering an emergency response by the vehicle and/or the smartphone when the vehicle fails to receive a response to the checkup data from the smartphone within a response time period.

A method includes retrieving a plurality of indications of cardiac events in a patient, heart rates of the patient during the cardiac events, and durations of the cardiac events. The method also includes selecting a subset of indications from the plurality of indications based on the heart rates of the patient during the cardiac events and the durations of the cardiac events and sorting the subset of indications based on heart rates of the patient during the cardiac event indicated by the subset of indications and based on durations of the cardiac events indicated by the subset of indications to produce a sorted list of indications. The method further includes communicating, from the sorted list, an indication that is first in the sorted list for clinical review.

Techniques are disclosed for detecting arrhythmia episodes for a patient. A medical device may receive one or more sensor values indicative of motion of a patient. The medical device may determine, based at least in part on the one or more sensor values, an activity level of the patient. The medical device may determine a heart rate threshold for triggering detection of an arrhythmia episode based at least in part on the activity level of the patient. The medical device may determine whether to trigger detection of the arrhythmia episode for the patient based at least in part on comparing a heart rate of the patient with the heart rate threshold. The medical device may, in response to triggering detection of the arrhythmia episode, collect information associated with the arrhythmia episode.

A system 300 and method for biologically monitoring the fitness of an athlete, and providing a warning 338 when an overtraining condition is determined in order to reduce injury. Through implementation of an efficient system architecture, micro-artificial intelligence use is practical for mobile situations where internet coverage is deficient or non-existent.

Monitoring vital parameters of a wearer of a compression garment by analyzing a pressure signal waveform indicative of a fluid pressure in an inflatable and deflatable bladder of the compression garment. Analyzing the pressure signal waveform for an oscillating amplitude as a function of time and/or a representation of a pulse of the wearer provides an indication of blood pressure of the wearer.

The present invention is directed to a system for monitoring a physiological parameter of a cyclist, and methods of using the system. The system comprises a garment, a sensor, and a signal processor. The garment is configured to be worn by the cyclist. The sensor is fixedly coupled to the garment and configured to measure a signal representative of the physiological parameter during pedaling. The signal processor is operatively coupled to the sensor and configured to determine a diagnosis based on the measured signal. An alert is generated in response to the diagnosis substantially in real time.

A method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy is provided. The method includes receiving cardiac data and determining a cardiac index based upon the cardiac data. The method includes determining an increased risk of death associated with epilepsy if the indices are extreme, issuing a warning of the increased risk of death and logging information related to the increased risk of death. Also presented is a second method for determining and responding in real-time to an increased risk of death relating to a patient with epilepsy comprising receiving at least one of arousal data, responsiveness data or awareness data and determining an arousal index, a responsiveness index or an awareness index, where the indices are based on arousal data, responsiveness data or awareness data respectively. The second method includes determining an increased risk of death related to epilepsy if indices are extreme values, issuing a warning of the increased risk of death and logging information related to the increased risk of death. A computer readable program storage device is also provided. Also provided is a method for receiving body data, determining a cardiac, an arousal, a responsiveness, or a kinetic index, determining an increased or increasing risk of death over a first time window relating to a patient with epilepsy and issuing a warning and logging relevant information.

An intelligent wearable device (1) and system having an alarm function, comprising: an alarm detection apparatus (11), a main control apparatus (12), an evidence collection apparatus (14) and an alarm transmission apparatus (13). When the alarm detection apparatus (11) determines that an abnormal situation has occurred, the alarm detection apparatus (11) sends an alarm signal to the main control apparatus (12); the main control apparatus (12) alarms according to the alarm signal; and the evidence collection apparatus (14) acquires evidence collection information, and the alarm transmission apparatus (13) sends the alarm information and evidence collection information to a background operation server (2). The intelligent wearable device (1) and system support various alarm ways, automatically send the alarm information to the background operation server (2) and can also send the alarm information to a designated contact person at the same time, the background operation server (2) sends the alarm information to a public security department, a medical department, a fire department, a traffic management department and so on so as to handle the warning condition, an environment safety monitoring function and a food safety monitoring function are achieved, and the situation that no person accepts the alarm can be avoided.
