    Abstract: Described herein are methods, devices, and systems that monitor heart rate and/or for arrhythmic episodes based on sensed intervals that can include true R-R intervals as well as over-sensed R-R intervals. True R-R intervals are initially identified from an ordered list of the sensed intervals by comparing individual sensed intervals to a sum of an immediately preceding two intervals, and/or an immediately following two intervals. True R-R intervals are also identified by comparing sensed intervals to a mean or median of durations of sensed intervals already identified as true R-R intervals. Individual intervals in a remaining ordered list of sensed intervals (from which true R-R intervals have been removed) are classified as either a short interval or a long interval, and over-sensed R-R intervals are identified based on the results thereof. Such embodiments can be used, e.g., to reduce the reporting of and/or inappropriate responses to false positive tachycardia detections.

    Abstract: The present invention provides a PHHM for the measurement of a subject's BP and, optionally, one or more other vital signs, comprising a housing located on a PHHCD or a hand-held component of a computing system; a blood flow occlusion means located in the housing such that, when the housing is located on the PHHCD or the hand-held component, an open surface of the blood flow occlusion means is available to be pressed against a body part of the subject or to have a body part of the subject pressed against it; a pressure sensor adapted to provide an electrical signal indicative of the pressure applied to or by the open surface; a means for detecting the flow of blood in the body part of the subject when pressure is applied to or by the open surface; and means for receiving electrical signals from the pressure sensor and the blood flow detecting means and for transmitting electrical signals indicative of the pressure and blood flow to the processor of the PHHCD or the computing system, wherein the processor of the PHHCD or computing system is adapted to process signals acquired by the pressure sensor and the blood flow detecting means to provide at least a measurement of the BP of a subject, the processor is further adapted to carry out a process to measure a DBP value and a SBP value, the DBP and the SBP values are estimated in such a way that the difference between the measured optical signals and those that would be generated by the estimation of the DBP and SBP values is minimized or the DBP and the SBP values are estimated in such a way that the difference between the measured incremental pressure signals and those that would be generated by the estimation of the DBP and SBP values is minimized. The present invention also provides alternative PHHMs and SADs for use in such PHMS.

    Abstract: A method includes receiving a plurality of raw PCG data inputs; applying at least one binary classification technique to each of the raw PCG data inputs to generate a respective plurality of filtered PCG data inputs; applying at least one divide-and-conquer algorithm to detect heartbeat compartments in each of the plurality of the filtered PCG data inputs based, at least on part, on assumptions that noise signals and S1-S2 alternation acoustic signals are non-stationary over a one-minute time interval; classifying each compartment of the heartbeat compartments in each of the plurality of the filtered PCG data input as a maternal compartment or a fetal compartment based at least on a plurality of referenced maternal QRS positions; combining a plurality of maternal compartments to identify at least one actual maternal heartbeat; combining a plurality of fetal compartments to identify at least one actual fetal heartbeat.
