Claim 1
Independent Claim
226 words
A system for collecting and displaying data for cardiac diagnosis, comprising means for transducing into electrical signals energy waves detectable at the suface of the body emanating from the cardiovascular system; broad band means for recording the output of said transducer corresponding to at least a segment of a given heart beat; a voltmeter for measuring and indicating the instantaneous voltage of electrical signals; means for repetitively feeding given portions of said recorded segment to said voltmeter; means for controlling said voltmeter to measure and indicate the instantaneous voltage of a succession of said portions sequentially and separately in extremely short intervals and for storing said indications to provide a composite stored replica of the given short portions of the wave form of said segment of said signals corresponding to a given short period of time which short period encompasses a multiplicity of said extremely short intervals; means for deriving from said stored replica the entire frequency content of said wave form for said short portion and for recording same graphically in coordinates of time, frequency and amplitude; and means for controlling the voltmeter controlling means to index successively to measure, store, derive and record the frequency contents of successive short portions of said wave form following said given short portion, whereby a three dimensional recordation of the time-frequency-amplitude content of said wave form is produced.
Claim 2
Independent Claim
226 words
A system for collecting and displaying data for cardiac diagnosis, comprising means for transducing into electrical signals energy waves detectable at the suface of the body emanating from the cardiovascular system; broad band means for recording the output of said transducer corresponding to at least a segment of a given heart beat; a voltmeter for measuring and indicating the instantaneous voltage of electrical signals; means for repetitively feeding given portions of said recorded segment to said voltmeter; means for controlling said voltmeter to measure and indicate the instantaneous voltage of a succession of said portions sequentially and separately in extremely short intervals and for storing said indications to provide a composite stored replica of the given short portions of the wave form of said segment of said signals corresponding to a given short period of time which short period encompasses a multiplicity of said extremely short intervals; means for deriving from said stored replica the entire frequency content of said wave form for said short portion and for recording same graphically in coordinates of time, frequency and amplitude; and means for controlling the voltmeter controlling means to index successively to measure, store, derive and record the frequency contents of successive short portions of said wave form following said given short portion, whereby a three dimensional recordation of the time-frequency-amplitude content of said wave form is produced.
Claim 3
Dependent Claim
96 words
A system as defined in claim 1 further characterized by means for separately transducing into electrical signals a plurality of forms of said energy waves; means for recording said separately derived signals in separate recording channels; means for measuring and deriving the time, frequency, and amplitude content of each form as defined in claim 1 separately, and means for recording same one directly over the other on the coordinates on the same graph each in a self distinguishing form; whereby a composite picture of a plurality of forms of data is presented in a single graph.
Claim 4
Dependent Claim
25 words
A system as defined in claim 2 further characterized by said means for transducing said energy waves including EKG, sound, phono-doppler, and pulse wave transducers.
Claim 5
Dependent Claim
26 words
A system as defined in claim 3 further characterized by said sound transducer comprising means for transducing sounds from 10 Hz to at least 20 kHz.
Claim 6
Dependent Claim
19 words
A system as defined in claim 2 further characterized by means for displaying the respective forms in different colors.
