    摘要: The technology described in this document can be embodied in a method that includes receiving optical data including information associated with a subject, and determining from the optical data, a first and a second dataset. The first dataset represents time-varying color change at a first body part of the subject. The second dataset represents time-varying characteristics at a second body part of the subject. The method includes identifying a first point in the first dataset, and a second point in the second dataset. The first point represents a time at which a pulse pressure wave traverses the first body part of the subject, and the second point represents a time at which the pulse pressure wave traverses the second body part of the subject. A pulse transit time (PTT) between the first and second body parts can be calculated as a difference between the first and second points.

    摘要: Various examples are provided for non-contact vital sign acquisition. Information can be provided regarding vibrations of a target using a radar signal such as, e.g., non-contact vital sign measurement. Examples include estimation of heart rate, change in heart rate, respiration rate, and/or change in respiration rate, for a human or other animal. Implementations can produce one or both rates of vibration and/or change in one or both rates of vibration for a target other than an animal or human experiencing two vibrations at the same time, such as a motor, a vehicle incorporating a motor, or another physical object. Some implementations can estimate the respiration movement in the radar baseband output signal. The estimated respiration signal can then be subtracted from radar signals in the time domain and, optionally, can be further enhanced using digital signal processing techniques, to produce an estimate of the heartbeat pulses.

    摘要: A system and method are provided for determining electrophysiological data. The system comprises an electronic control unit that is configured to receive electrical signals from a set of electrodes, receive position and orientation data for the set of electrodes from a mapping system, compensate for position and orientation artifacts of the set of electrodes, compose cliques of a subset of neighboring electrodes in the set of electrodes, determine catheter orientation independent information of a target tissue, and output the orientation independent information to a display. The method comprising receiving electrogram data for a set of electrodes (80), compensating for artifacts in sensor positions in the mapping system (81), resolving the bipolar signals into a 3D vector electrogram in the mapping system coordinates (82), manipulating observed unipolar voltage signals and the tangent component of the e-field to estimate the conduction velocity vector (83), and outputting the catheter orientation independent information (84).

    摘要: The invention provides a body-worn system that continuously measures pulse oximetry and blood pressure, along with motion, posture, and activity level, from an ambulatory patient. The system features an oximetry probe that comfortably clips to the base of the patient's thumb, thereby freeing up their fingers for conventional activities in a hospital, such as reading and eating. The probe secures to the thumb and measures time-dependent signals corresponding to LEDs operating near 660 and 905 nm. Analog versions of these signals pass through a low-profile cable to a wrist- worn transceiver that encloses a processing unit. Also within the wrist- worn transceiver is an accelerometer, a wireless system that sends information through a network to a remote receiver, e.g. a computer located in a central nursing station.

    摘要: A method for detecting the onsets or offsets of heart depolarization or repolarization waves (e.g. QRS-complex or T-wave) includes determining a slope of a cardiac electrogram. A threshold value is determined based on a maximum of the slope of the cardiac electrogram, and a last point of the cardiac electrogram before the slope of the cardiac electrogram crosses the threshold is identified as one of an onset or an offset of a wave. The method may further include receiving an indication of local ventricular motion associated with a cardiac contraction, and determining an electromechanical delay between the identified onset and the local ventricular motion. Some examples include providing the electromechanical delay for configuration of cardiac resynchronization therapy (CRT), e.g. selection of pacing sites.
