Problems solved by technology

However, the basic ECG data of the Chinese Garden Dog has not been reported yet.
Due to the lack of basic data of the ECG of the Chinese Pastoral Dog, in the process of analyzing the ECG of the Chinese Pastoral Dog, the standard customization of each waveform is different, which cannot provide effective reference for clinicians

Embodiment 1

[0040] Taking 400 adult Chinese pastoral dogs (half male and half female, 6-10kg) as the experimental subjects, the experiment was carried out in a dog farm. The farm adopted a fully enclosed feeding method, kept in cages, and all fed mixed extruded feed.

[0041] The electrocardiogram is measured by:

[0042] The dog took the natural standing position, put it in the safety frame under non-anesthesia state before eating, inserted the needle electrodes of the electrocardiogram machine into the subcutaneous of the limbs in sequence, and after the animal was stable, collected six samples of I, II, III, aVR, aVL and aVF in sequence Lead ECG signal.

[0043] The collected ECG signal is filtered to obtain the processed signal.

[0044]Digimizer medical image analysis software is used to analyze the processed signal, and 2400 ECG data of 6 leads are obtained, each data includes: P wave interval, P wave amplitude, QRS wave interval, QRS wave amplitude, T wave interval , T wave ampli...

Abstract

The invention discloses a method for obtaining a standard parameter range of an adult Chinese rural dog electrocardiogram. The method comprises the following steps of (1) collecting electrocardiogramsignals of each lead; (2) performing filtering processing to obtain processing signals; (3) analyzing the processing signals to obtain parameters of P wave intervals, P wave amplitudes, QRS wave intervals, QRS wave amplitudes, T wave intervals, T wave amplitudes, PR intervals and QT intervals of each lead; (4) performing scatter diagram analysis on the parameters of step (3), and discarding the parameters with large dispersion; (5) calculating mean values and standard deviations of each parameter; (6) using a QT correction formula for correcting the parameters of the QT intervals; (7) correcting T wave data, and obtaining the standard parameter range of the adult Chinese rural dog electrocardiogram. The method establishes the basic data of the Chinese rural dog electrocardiogram for the first time, and fills the blank of the technical field.

Description

technical field [0001] The invention relates to the technical field of biomedical signal processing, in particular to a method for obtaining the standard parameter range of an electrocardiogram of an adult Chinese pastoral dog. Background technique [0002] Electrocardiogram (ECG) is the use of electrocardiogram detection equipment to record the electrical activity changes generated by each cardiac cycle of the heart from the body surface. What the electrocardiogram records is the curve of voltage changing with time, which reflects the electrical activity process of heart excitation. At present, ECG is widely used as intermediate processing data in the basic function and pathological research of the heart. [0003] With the rise of the dog breeding industry, the monitoring of physiological indicators of dogs has become more and more standardized. There have been some reports on the ECG of dogs in recent years, but due to the differences in breed, gender, age, and breeding ...
