Description
Technical field
The present invention relates to medical electrocardiosignal monitoring arts, more particularly to a kind of automatic switchover of cardiac diagnosis lead mode of operation
Method and apparatus.
Background technology
Electrocardio（Abbreviation ECG）Signal is reflection of the heart in a period of time interior electrical activity, is gathered by skin electrode, so
Skin electrode is connected with cardiac diagnosis lead-line again afterwards, and electrocardiosignal is transferred in electrocardio measuring circuit.Skin electrode is typically placed
At each position such as extremity and chest.
In cardiac monitoring, 3 leads, 5 leads, 12 lead Three models are mainly used.Wherein, 3 lead patterns are using right
Arm（RA）, left arm（LA）, left lower limb（LL）Three limb lead lines, can show I, II, III 3 road waveforms.Due in 3 lead patterns
Under, only three conducting wires, and electrocardiosignal is differential signal, per pass waveform is as calculating by two different conducting wires
Lead, the 3rd is got as driving lead, therefore under 3 lead patterns, three road waveforms can not be shown simultaneously, be only able to display which every time
In one waveform.5 lead patterns use right arm（RA）, left arm（LA）, left lower limb（LL）, right lower limb（RL）, chest lead（V）Five leads
Line, can show I, II, III, seven road waveform of avR, avL, avF, V, seven road waveforms can be shown simultaneously.12 lead patterns use right arm
（RA）, left arm（LA）, left lower limb（LL）, right lower limb（RL）, chest lead（V1~V6）Ten conducting wires, can show I, II, III, avR,
12 road waveform of avL, avF, V1, V2, V3, V4, V5, V6,12 road waveforms can be shown simultaneously.
In general, electrocardio measuring circuit can eliminate the common mode interference signal of human body using actuation techniques, so as to carry
High electrocardiosignal quality.Actuation techniques mainly by the common-mode voltage of limb lead taking-up human body, then common-mode voltage Jing again
Anti-phase amplification etc. is fed back in certain lead after processing, and the lead referred to as drives lead, and this driving lead is not involved in electrocardio and believes
Number calculate, with this reach eliminate human body exist common mode interference signal effect.Under 3 lead patterns, when showing I waveform, left lower limb
（LL）To drive lead, when showing II waveform, left arm（LA）To drive lead, when showing III waveform, right arm（RA）Lead to drive
Connection.Under 5 leads and 12 lead patterns, drive lead using most for right lower limb（RL）, but other leads are also can select to drive
Lead.
In use, because of situations such as the movement or other collisions of patient, conducting wire can be caused to come off, non-driven is led
When connection comes off, electrocardiosignal still provides for measurement, does not affect to use, but electrocardiosignal may be caused to examine after driving lead-fail detector
Survey, prior art, it can be determined that lead-fail detector, by whether receive corresponding bioelectrical signals, if it did not, or signal not
It is normal then be judged as that lead (include drive lead) comes off.Only accordingly reported to the police after lead-fail detector is driven, user must be again
New connection drives conducting wire just be continuing with, and so operates not only relatively time-consuming, uses also inconvenient, and reduces survey
Amount efficiency.
The content of the invention
The purpose of the present invention is for problem described above, there is provided a kind of method that cardiac diagnosis lead mode of operation automatically switches
And device.
To solve above technical problem, the technical scheme that the present invention is provided is：
The device that a kind of cardiac diagnosis lead mode of operation automatically switches, including
Lead mode decision module, for judging current cardiac diagnosis lead mode of operation；
Lead-fail detector judge module, is connected with described lead mode decision module, for being judged as 12 leads or 5 leading
Drive whether lead comes off under gang mould formula, or whether arbitrary lead comes off under 3 lead patterns；
Lead mode switch module, is connected with described lead-fail detector judge module, for if it is determined that 12 leads or 5
Lead-fail detector is driven under lead pattern, being then switched under other lead patterns carries out ECG signal sampling；
Prompting alarm module, is connected with described lead-fail detector judge module, for if it is determined that 12 leads or 5 leads
Arbitrary lead-fail detector under lead-fail detector, or 3 lead patterns is driven under pattern, then alarm is exported.
Further, also include,
Module is pre-seted, is connected with described lead mode decision module and lead-fail detector judge module, for advance
Cardiac diagnosis lead pattern and 12 leads or the driving lead under 5 lead patterns are set.
The method that a kind of cardiac diagnosis lead mode of operation that the present invention is provided automatically switches, comprises the steps：
Step 1, judge current cardiac diagnosis lead mode of operation；
Step 2, continue to judge to drive whether lead comes off under the pattern if being judged as 12 lead patterns, if it is determined that driving
Dynamic lead-fail detector, then into step 3；
Step 3, judge whether arbitrary lead comes off under 3 lead patterns, if it is determined that arbitrary lead does not take off under the pattern
Fall, then into step 4, if it is determined that arbitrary lead-fail detector under the pattern, then into step 5；
Step 4, it is switched under 3 lead patterns and carries out ECG signal sampling；
Step 5, alarm are simultaneously exported.
Further, also include that return to step 2 in scheduled duration carry out the step of duplicate detection after the step 5
Suddenly.
Further, also include that return to step 2 in scheduled duration carry out the step of duplicate detection after the step 4
Suddenly.
Further, in the step 2, if it is determined that driving lead not come off, then 12 lead patterns are kept not
Change carries out ECG signal sampling, and in scheduled duration repeats step 2.
The present invention provides a kind of method that cardiac diagnosis lead mode of operation automatically switches, and comprises the steps：
Step 1, judge current cardiac diagnosis lead mode of operation；
Step 2, continue to judge to drive whether lead comes off under the pattern if being judged as 5 lead patterns, if it is determined that driving
Dynamic lead-fail detector, then into step 3；
Step 3, judge whether arbitrary lead comes off under 3 lead patterns, if it is determined that arbitrary lead does not take off under the pattern
Fall, then into step 4, if it is determined that arbitrary lead-fail detector under the pattern, then into step 5；
Step 4, it is switched under 3 lead patterns and carries out ECG signal sampling；
Step 5, alarm are simultaneously exported.
Further, in the step 2, if it is determined that drive lead do not come off, then keep 5 lead patterns it is constant enter
Row ECG signal sampling, and step 2 is repeated in scheduled duration.
Further, in the step 2, continue to judge arbitrary lead under the pattern if being judged as 3 lead patterns
Whether come off,
If it is determined that arbitrary lead does not come off, then keep that 3 lead mode of operations are constant to carry out ECG signal sampling；
If it is determined that arbitrary lead-fail detector, then alarm export.
The invention provides a kind of cardiac diagnosis lead mode of operation automatic switching method and device, in 12 leads and 5 lead moulds
Under formula, the judgement whether lead comes off is driven, if driving lead-fail detector, 3 lead mode of operations can be automatically switched to, after
It is continuous that electrocardiosignal is measured.Due to only having three conducting wires under 3 lead patterns（RA、LA、LL）, electrocardiosignal is difference
Signal, so wherein two used as lead is calculated, the 3rd can not all carry out electrocardio as driving lead, arbitrary lead-fail detector
The measurement of signal, therefore under 3 lead patterns, arbitrary lead-fail detector cannot be switched to other patterns, only carry out corresponding warning and carry
Show.
The program has been due to having used lead automatic switchover technology, it is to avoid because driving lead-fail detector, and caused electrocardio without
Method measures problem, makes user not only save time when in use but also convenient, is that other patterns or reconnect driving are led without the need for manual switching
On line, just can continue to measure electrocardiosignal, and Consumer's Experience is more preferable.
