Abstract
The invention discloses an automatic gain-regulated output method for waveform drawing of a multi-channel electrocardiograph, which comprises the following steps: (1) detecting and calculating the voltage amplitude of an electrocardiographic waveform of each channel; (2) determining the magnitude of the automatic gain of the electrocardiographic waveform of each channel based on the magnitude of the voltage amplitude obtained in the step (1); (3) carrying out gain processing on an original signal of the electrocardiographic waveform of each channel based on the magnitude of the automatic gain; and (4) drawing the electrocardiographic waveforms obtained after gain processing on an interface, recording and outputting. The invention simultaneously meets the requirements for both interface displaying and recording and outputting, and can achieve a better balance between the both. When being used for an electrocardiograph with a large number of channels (e.g. 12 channels), the automatic gain-regulated output method provided by the invention can achieve a more obvious optimization effect.
Description
Technical field
The present invention relates to a kind of control method of waveform, particularly a kind of multichannel electrocardiograph waveform is drawn automatic gain and is regulated output intent.
Background technology
In the application of electrocardiograph, electrocardiograph detects the waveform that obtains and can show on the interface on the one hand, also can write down and export by equipment such as monitors on the other hand.When by equipment such as monitors the result being write down and exporting, waveform generally is that set gain and speed writes down during according to interface display, promptly the interface of electrocardiograph draw and the waveform recording use be same gain.And in the gain of present interface display was provided with, it generally all was that the automatic gain function of electrocardiograph automatically adjusts that the user uses more.The realization of automatic gain function is a problem of comparing the comparison difficulty, current general way is, drawing area according to the ecg wave form of each passage is adjusted wave shape gain, exceeds wave regions so that wave-shape amplitude is not too large, simultaneously again can be too not little and influence observing effect.In fact it is little suitable on electrocardiograph that above-mentioned this automatic gain is handled, as mentioned before, draw at the interface of electrocardiograph and waveform recording is used is same gain, simple effect of only giving when deciding the automatic gain size undoubtedly can badly influence to write down based on the interface.Owing to compare the effect of interface display, that the user values more is record output result, because for the user, the waveform that is write down is only the basis of carrying out ECG Signal Analysis.Therefore, based on above-mentioned discussion, at present this based on the per pass waveform drawing area and determine the method for automatic gain to change, particularly for the more electrocardiograph of number of channels (as 12 passages), because it is bigger that the automatic gain size is subjected to the restriction of drawing area, so the effect of waveform recording output can be subjected to seriously influencing more.
Summary of the invention
For addressing the above problem, the invention provides a kind of multichannel electrocardiograph waveform of having taken into account the effect of interface display and record output and draw automatic gain adjusting output intent.
The technical scheme that the present invention is adopted for its problem of solution is:
A kind of multichannel electrocardiograph waveform is drawn automatic gain and is regulated output intent, may further comprise the steps:
(1) detects and calculates the voltage amplitude of the ecg wave form of each passage;
(2) based on the big or small automatic gain size that determines the ecg wave form of each passage of the voltage amplitude of step (1) gained;
(3) primary signal of the ecg wave form of each passage is carried out gain process based on the automatic gain size;
(4) ecg wave form with gained after the gain process is drawn on the interface, go forward side by side line item and output.
The invention has the beneficial effects as follows: the present invention is actually according to the voltage amplitude of ecg wave form and adjusts wave shape gain automatically, decide automatic gain to vary in size with tradition according to this external factor of drawing area of each passage ecg wave form, the size of voltage amplitude can reflect the inherent signal characteristic of ecg wave form, based on the signal characteristic close relation of automatic gain that these intrinsic factor determined size with ecg wave form, utilize ecg wave form that this automatic gain size carries out gained after the gain process actual effect of reflected waveform effectively, no matter still writing down the demand of output facet aspect interface display can be taken into account, can reach a balance preferably between the two, above-mentioned optimization effect can be more obvious when automatic gain of the present invention was regulated output intent and used on the electrocardiograph of number of channels more (as 12 passages).
The specific embodiment
A kind of multichannel electrocardiograph waveform of the present invention is drawn automatic gain and is regulated output intent, may further comprise the steps:
(1) detect and calculate the voltage amplitude of the ecg wave form of each passage, the size of this voltage amplitude can reflect the inherent signal characteristic of ecg wave form effectively;
(2) based on the big or small automatic gain size that determines the ecg wave form of each passage of the voltage amplitude of step (1) gained, this automatic gain size varies in size with the automatic gain that determines based on this extrinsic factor of drawing area of the ecg wave form of each passage, its ecg wave form with reality is closely connected, and the automatic gain size is not influenced by the size of drawing area;
(3) primary signal of the ecg wave form of each passage is carried out gain process based on the automatic gain size, can form one through ecg wave form after the gain process and be easy to observe and suitable waveform that can complete reflected signal details;
(4) ecg wave form with gained after the gain process is drawn on the interface, go forward side by side line item and output, because the voltage amplitude that this automatic gain size is based on ecg wave form is determined, therefore the effect that writes down output waveform can at first be guaranteed, though portion waveshape can occur because of the excessive interface display condition of poor of automatic gain, but guaranteeing that under the successful prerequisite of record output be acceptable, these treated waveforms can reach reasonable balance under most of situation on the effect of interface display and record output.
Automatic gain adjusting output intent of the present invention effect on a fairly large number of multichannel electrocardiograph is more obvious, with 12 passage electrocardiographs is example, 12 traditional passage electrocardiographs are owing to the shared drawing area of the ecg wave form of each passage is less, with this drawing area serves as that basis decision automatic gaining effect can make the waveform effect of the output of being write down produce bigger defective, so carries out the difficult realization of analysis meeting based on the waveform of this record output.Adopt method of the present invention to carry out that then can there be above defective in the record output waveform of gained behind the automatic gain.
