The long route cardiogram figure of representative is not replaced.First electrocardio scatter plot science summit on May 10th, 2011 and electrocardio
Scatterplot graphics composition is vertical, and meeting is in Beijing holds, from Beijing and participant expert in all parts of the country around Non-linear Chaos Theory, non-
How linear method is applied to cardiac diagnosis, how to recognize and use electrocardio scatter plot, electrocardio scatter plot to dynamic RR interphase
Physiological and pathological information, ventricular fibrillation and the spin wave theory of expression and the offer of sequence variation are discussed.Since then, it is dissipated based on electrocardio
The ambulatory ECG analysis of point diagram is paid more and more attention.Common Lorenz scatter plot uses the company in 24 hours long route cardiogram figures
Continuous RR interphase (Rn, Rn+1) does scatter plot as scatterplot coordinate in rectangular coordinate system.It can reflect the variation of adjacent R R interphase,
The nonlinear characteristic of heart rate variability is disclosed, dynamic ECG can be qualitatively judged.But Lorenz scatter plot lacks
Timing information in former electrocardiogram cannot reflect the time trend of HRV, especially be easy to mix the scatter plot of different time
Together.In order to more effectively be classified and retained the timing information that electrocardiosignal has to the not normal rhythm of the heart, when occurring
Between scatter plot, but how to solve to time scatter plot each point carry out ecg wave form control be anxious to be resolved ask
Topic.
The content of present invention
The present invention is directed to overcome above-mentioned the deficiencies in the prior art, a kind of dynamic electrocardiogram time scatter plot conversed analysis side is provided
Each of time scatter plot scatterplot or the scatterplot of selection area can inversely be found the electrocardio wave corresponding to it by method, the method
Shape.
In order to achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of dynamic electrocardiogram time scatter plot conversed analysis method, includes the following steps：
S1：The ambulatory ecg signal that acquisition comes is carried out to automatically analyze identification R wave position；
S2-1：According to the R wave position that step S1 is identified, using the interval of adjacent R wave as ordinate, the interval of adjacent R wave
Also it is used as abscissa, draws time scatter plot；
S2-2：The range of choosing will be enclosed on time scatter plot, carries out reverse operation；
S2-3：The multiple electrocardiogram segments found by time scatter plot reverse method are shown, any heart is selected
The amplification of electrograph segment, is checked for comparison.
Preferably, the step S1 includes the following steps：
S1-1：12 are carried out to patient and leads dynamic electrocardiogram (ECG) data acquisition；
S1-2：12 next to acquisition lead electrocardiogram (ECG) data and are removed interference, then carry out R wave positioning again.
Preferably, in the step S2-1, with (Rn, Rn) as the scatterplot coordinate in rectangular coordinate system, wherein Rn is represented
N-th of RR interphase length, ordinate unit millisecond, abscissa unit minute, and mark time scatterplot, the normal sinus of ventricular premature beat
The time scatterplot of property heartbeat.
Preferably, in the step S2-2, range x1 to the x2 for selecting the x coordinate of range to represent the time is enclosed, encloses and y is selected to sit
Mark represents the range y1 to y2 of RR interphase, and the period x1 for filtering out the generation of RR interphase is determined according to selected time range<x<
X2 determines the RR interphase y1 of screening further according to selected RR interphase range<y<y2.
Method can effectively auxiliary operation person will be different for dynamic electrocardiogram time scatter plot conversed analysis provided by the invention
The ecg wave form of interphase range and period filter out, to carry out batch edit operation.
