It relates to the field of displaying the heart-rate data collected in an exercise test, in particular to a method for achieving a panoramic display during Electrocardiogram Exercise Test by using a time axis, comprising following steps: (a) building a horizontal axis (X axis) in units of time as a time axis, and building a vertical axis (Y axis) in units of heart rate, therefore forming a two-dimensional tendency chart; (b) collecting and storing real-time 12-lead ECG raw data, acquiring and storing real-time heart rate data, (c) setting a time vernier, wherein in a default status, the time vernier is located at the current moment, and it is connected with 12-lead ECG raw data.

Improved human health monitoring is provided in the context of sensor measurements of typical vital signs and other biological parameters, by a system and method using an empirical model of the parameters and disposed to estimate values of the parameters in response to actual measurements. Residuals resulting from the difference between the estimates and actual measurements are analyzed for robust indications of incipient health issues. Residual analysis is both more robust and more sensitive than conventional univariate range checking on vital signs.

This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.

A two-dimensional visual display that allows for the user and/or another individual, such as the user's spouse, to experience self-evident, abnormally complex elevated heart rate arrhythmia. The system of the present invention uses a heart rate monitor, along with data analysis, to provide the user with a visual display, seismic feel, and/or aural feedback that allow for the user to be quickly alerted as to any arrhythmia, thereby signaling to the user to change their activity in order to avoid sudden cardiac death.

The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and/or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

An ergonomically designed wireless wearable smart band pair for continuous ECG monitoring is disclosed. The pair comprises primary and secondary smart bands with integrated electrodes that are provided with switches for enabling desired electrodes during data acquisition. When the smart bands are worn around the two limbs, electrodes contact the skin. The primary smart band sets all possible states of the electrode switches and acquires biopotential data from the first wrist while the secondary smart band simultaneously acquires biopotential data from the second wrist and sends it wirelessly to the primary smart band. The primary smart band processes biopotential data via digital and analog signal conditioning and fuses information to acquire high-fidelity ECG data as per Einthoven's law without need for completing a circuit via leads and/or holding auxiliary electrodes. The primary smart band analyzes ECG data in real-time, generates pertinent alarms, stores data locally, and wirelessly transmits information to external devices.

A method for identifying cardiac bradycardia behavior may include acquiring pulse volume wave data from a sensor associated with a patient, and calculating metrics associated with peaks detected therein. The metrics may include changes in peak amplitudes of pulse volume peaks and in the times of occurrence of pulse volume peaks. Alternative metrics may include changes in frequency domain parameters derived from the time domain pulse volume wave data. Peak amplitude values may be compared to an amplitude baseline, and differences in successive peak occurrence times may be compared to a time baseline. Cardiac bradycardia behavior may be identified by a combination of a decrease in the pulse volume peak amplitude and an increase in successive peak occurrence times. A system to implement the method may include a computing device in data communication with a photo-plethysmograph. Alternative sensors may include a blood pressure cuff and an ECG device.

A self-inflating personal flotation device (SIPFD) configured to be wom by a wearer and aid the wearer automatically. The SIPFD may communicate with a global communication network and pressurized gas cartridge assembly based on a triggering event. The SIPFD may have a wearable data transmitter of a heartbeat device; a water depth device; and a geolocation device. The SIPFD may have a neck inflation device and a torso inflation device both connected to the pressurized gas cartridge assembly to enable the pressurized gas cartridge to inflate the neck and torso inflation devices when prompted. The prompt may be automatic or on request and be performed using an actuator mechanically communicating with the pressurized gas cartridge assembly to: (i) inflate the neck and torso inflation devices; and (ii) deflate the neck and torso inflation devices associated with a wearer.

A garment (e.g., a shirt) for monitoring biometric properties of the wearer of the garment is disclosed. The garment may include sensors for monitoring or assessing biometric properties such as, but not limited to, respiration properties, heart properties, and motion properties. These properties may be assessed together to provide an assessment of vital signs and body position (e.g., three-dimensional body position) of the wearer of the garment.

An apparatus for monitoring a biosignal of a cyclist includes an electrocardiogram measuring sensor measuring an electrocardiogram signal of a cyclist, an electromyogram measuring sensor measuring an electromyogram signal of the cyclist, and a determination module determining muscle fatigue of the cyclist, based on at least one of a change in a heart rate of the measured electrocardiogram signal and a change in a frequency component of the measured electromyogram signal.
