  • Patent number: 9820667
    Abstract: There is a method and system for detecting heartbeat irregularities comprising the steps of receiving a dataset representative of at least one waveform, the at least one waveform indicative of a subject's heart activity over a predetermined period of time; identifying from the data representative of at least one waveform, a plurality of peaks, each peak corresponding to a heartbeat; identifying from the predetermined period of time the time occurrence of each peak; calculating the difference (duration) between the time occurrence of each peak with its adjacent peak; determining the difference between each duration; classifying the absolute value of the difference into one of at least three intermediate categories; wherein each intermediate category comprises a specified range such that the absolute value is categorized into the intermediate category if it falls between the range; the intermediate categories further providing an indication of whether the subject has heartbeat irregularity.

  • Publication number: 20130304112
    Abstract: An apparatus and method for altering reflected arterial pulse of a body is disclosed. The apparatus comprises a belt having a compression member arranged to apply a pressure to the body, the belt being arranged to be positioned such that the compression member applies the pressure to one of at least two pressure points between the xiphis sternum and navel of the body, the belt adjustable to provide at least two pressure levels to each of the at least two pressure points and a blood pressure monitoring device arranged to obtain a beat-to-beat arterial pulse waveform when the pressure is applied at each of the pressure points and at each of the at least two pressure levels; and analyze the waveform to determine the optimum position for the compression device to apply the pressure to the body to alter the pulse waveform.
