Figure 4 shows a method of the present invention and also one in the embodiment according to original (raw) electrocardiogram signal after performing a filtering step of analyzing electrocardiogram signal during electrocardiogram signal graph shown and, after performing a filtering step of the present invention and one in the embodiment according to Figure 5 shows a electrocardiogram signal of a timing graph of Figure 4 subsequent to perform the differentiated electrocardiogram signal are disclosed. Figure 6 shows a section of the present invention and subsequent steps to perform the averaging differential electrocardiogram signal subsequent electrocardiogram signal graph shown in the embodiment according to one and, in the embodiment of the present invention also Figure 7 shows a QRS wave peak signal noise during peak signal according to a power on state for one threshold and determining method drawing and described, also shown in Figure 8 7 of Figure 5 timing graph threshold can vary according to method are disclosed. The steps are signal processing unit (110) can be performed.

QRS frequency band for detecting electrocardiogram signal of filtering by power, the following order through substrate.

1) low pass filtering, 2) band pass filtering, 3) differential, 4) an absolute value, 5) window section using average

Each filtering procedures filters can be implemented as follows.

First, low pass filtering a filter output relationship the following cleaning substrate.

Wherein, n is an index and data, and the output value of a manual or automatic y, x is an input of the filter value. In order n ms sampling rate coefficient changed according to unit and transfers but, when the sampling rate is 200Hz [t provided 25ms] to [n-a 5], [t provided 50ms] is [n-a 10] are disclosed.

The output of the second high pass filtering a filter z is referred to as, z is [t provided 60ms] x - y can be expressed by, wherein y is [n-a 1] y + x [t provided 120ms] - x implementation being. Y is a low-pass output of the filter, the all-pass filter be a x [t provided 60ms]. I.e., an all-pass filter by subtracting an output of the low pass filter is a high pass filter can be implemented.

After the output signal of the low-pass filter and a high pass filter original electrocardiogram signal is high pass filters can be the differentiator. Differentiated signals are shown in fig. 5 in the nanometer range.

Then, after the absolute value of the differentiated signals are, in one embodiment the window 80ms 80ms using absolute value window oppose amplifying top surface, such as QRS wave signal with large value also 6 can be achieved. I.e., QRS wave appears whenever an output signal having a relatively large value can be achieved.

Low pass filtering, high pass filtering, differentiate and average QRS signal having a peak value obtained takes in signals is transformed into the substrate. However, the QRS wave peak value representing all inner portion, each peak value determines whether or noise signal QRS fine accomplishing.

To this end each peak magnitude, then the relative position from last QRS wave, QRS peak value or maximum size of the differential signal to the and-gate determines whether the noise signal can be fine.

First previous peak value after the peak value in time are number 1 ignore other. Number 1 time is in one embodiment the implementation being 200ms. And, when an optical pickup device, and its original electrocardiogram signal peaks of value identifying whether one of the positive peak value and negative peak value base line if not change as follows.

In addition, peak value will appear from within one of the half maximum slope greater than previously before 360ms examines whether T wave to a user if not greater than 2000.

If QRS wave detecting more than a threshold QRS wave outputs, QRS wave detecting less than a threshold S. if noise signal to a user.

R a-R interval 1. 5 times greater than half peak value detection threshold within peak value unless a noise signals can appear later if the QRS wave peak value determines 360ms outputs an other.

The QRS wave detection threshold QRS wave with a peak value detection threshold and noise signals each anti-noise signals can be dynamically altered. I.e., the peak value of the magnitude of the recent peak 8 and noise signals to store, each median (median) can be detected from the threshold is determined.

The largest peak value QRS wave peak value in 8 seconds every second data initially test, and a noise signal after determining a detection threshold thus set to the value 0, 8 seconds since detection module determines such as on.

Figure 9 shows a threshold according to a timing graph of running rate therefrom forecast is preferably also are disclosed.

Updating such thresholds is a ratio of the running rate 0. 3 to 0. 4 0 up. 0001 (300 to 400 on drawing) and changed to MIT/BIH database when it is applied to unit, running rate is 0. 3470 (347 on drawing) when, total 91072 sensitivity and forecast is the bit 99 each. 745% and 99. 849% has been measured.

Association for the Advancement of Medical Instrumentation (AAMI) performance measurement is made from the PPG systems by applying a measure the performance standard ANSI/AAMI EC13, his 200Hz data sampling. Data process takes, and resulting comparison using the air number in the resampling physionet [...] WFDB tool kit.

Figure 10 shows a measuring device of the present invention also one in the embodiment according to animal electrocardiogram signal may be stored in a reference electrocardiogram data timing table are disclosed.

As one example, in the case of cats and dogs, and personal when dog, small-sized silk, silk features, formation silk is formed between the normal state of heart rate, electrocardiogram signal of P wave, PR interval, Q wave, QRS width, S wave, S wave segments, PR interval, etc. with information such as T wave. Such information can be obtained in a water system, this information signal processing unit (210) of memory unit (212) can be stored. Examples of such animal 10 also is not limited to, data can be stored in the memory against all aren't there. In addition, such a normal state of electrocardiogram data and stored in the memory, electrocardiogram signal measuring device is mounted on an animal types and size of setting information, and using the detected electrocardiogram signal, if it is judged that whether or not the corresponding animal can be electrocardiogram signal.

With, in the embodiment according to the electrocardiogram signal measuring device one animal of the present invention, can be installed simultaneously to a plurality of animals. In one example, veterinary hospital, like all mounted to zoo animal can be, in this case the main server determines whether judgment result from all animals in heart or more transmission 2000 KIPO. I.e., signal processing unit (210) number of control section (212) in memory unit (212) stored electrocardiogram data and the corresponding animal electrocardiogram signal detected from each animal of a steady-state difference comparing electrocardiogram data and normally only if main server by sending an abnormal signal, heart abnormality detector can be managing a plurality of animals.

The present invention refers to drawing one embodiment described with reference to the example shown in an exemplary to avoid a but which, if various deformation and equally therefrom art person with skill in the art will understand enabling other embodiment examples. The, true technical idea of the present invention techniques protection range defined by appended claims will generated by the range of registration.
