Description
Technical field
The invention belongs to electrocardiogram processing technology fields, more particularly to one kind is for predicting that arrhythmia cordis occurs for multipole individual
Risk surface electrocardiogram processing system.
Background technique
Electrocardiogram (ECG or EKG) is to record electricity caused by heart each cardiac cycle from body surface using electrocardiograph
The technology of activity change figure.Myocardial cell membrane is semi-permeable membrane, when quiescent condition, arranges the positively charged sun of certain amount outside film
Ion, the negatively charged anion of the identical quantity of the interior arrangement of film, film volta potential are higher than in film, referred to as polarized state.Quiescent condition
Under, since each position cardiac muscle cell of heart is all in polarized state, without potential difference, the potential curve that galvo-recorder is traced is flat
Directly, the as equipotential line of surface electrocardiogram.In the stimulation by some strength, permeability of cell membrane changes cardiac muscle cell
Become, poured in film in a large amount of cation short time, becomes film inner potential just by negative, this process is known as depolarization.To whole heart
For, potential change of the cardiac muscle cell from the internal membrane of heart into external membrane of heart sequence process of depolarization, the current potential traced by galvo-recorder
Curve is known as wave of depolarization, i.e., the P wave in atrium and the QRS wave of ventricle on surface electrocardiogram.After the completion of cell depolarization, cell membrane is arranged again
A large amount of cations out make film inner potential be restored to original polarized state by just becoming negative, this process from the external membrane of heart to the internal membrane of heart into
Row, referred to as multipole.Potential change in same cardiac muscle cell's process of repolarization traces out referred to as repolarization wave by galvo-recorder.By
Relatively slow in process of repolarization, repolarization wave is low compared with wave of depolarization.The repolarization wave in atrium is low and is embedded in the wave of depolarization of ventricle, body surface
Electrocardiogram is not easy to recognize.The repolarization wave of ventricle shows as T wave on surface electrocardiogram.After entire cardiac muscle cell's whole multipole, then
Secondary recovery polarized state, without potential difference between each position cardiac muscle cell, equipotential line is recorded in surface electrocardiogram.However, existing
Ecg signal acquiring equipment is not readily portable greatly, and needs wearing in continuous 24 hours that can just obtain complete assessment report, limits
The daily action of patient, while diagnosis needs the participation of doctor, is difficult to realize daily cardiomotility situation and rhythm abnormality
Self-monitoring, diagnosis and management；Meanwhile environment, position and state locating for the subject be when changing, in electrocardiogram
Intensity, the frequency of various interference signals can also change at any time, lead to the consistency reduction of ECG signal and waveform quality
Decline causes the workload of operator's follow-up editor, modification wrong report, failing to report phenomenon to influence the precision of software analysis result
Increase, working efficiency reduces.
In conclusion problem of the existing technology is:
Existing ecg signal acquiring equipment is not readily portable greatly, and wearing in continuous 24 hours is needed just completely to be commented
Estimate report, limit the daily action of patient, while diagnosis needs the participation of doctor, be difficult to realize daily cardiomotility situation with
And self-monitoring, diagnosis and the management of rhythm abnormality；Meanwhile environment, position and state locating for the subject be when changing,
Intensity, the frequency of various interference signals in electrocardiogram can also change at any time, the consistency of ECG signal is caused to reduce,
And waveform quality declines, to influence the precision of software analysis result, causes operator's follow-up editor, modification wrong report, fails to report now
The workload of elephant increases, and working efficiency reduces.
Alarm cannot carry out alert notice to the abnormal data of differentiation constantly in the prior art, reduce alarm velocity, make
Obtaining abnormal data cannot be found in time, reduce the operating accuracy and working efficiency of system；Printer cannot be quasi- in the prior art
Optimal solution is really obtained, electrocardiogram is subjected to printing to there is peak deviation, is unfavorable for obtaining accurate clearly electrocardiogram；It is existing
Have display in technology that cannot effectively avoid difference problem existing for the gray value of lamp point region and background area so that data by
The influence of contrast and brightness, display cannot quickly, clearly, accurately show electrocardiogram (ECG) data, electrocardiogram and the heart rate of acquisition
Abnormal data information.
