's.
More specifically, obtaining P-QRS-T ring according to the lead electrocardiogram after detecting P wave ring, qrs loop or T wave ring
Change interphase, and carries out heart rate value calculating.Such as, when vector ring is qrs loop, by filtering measurement (QRS) waveform section
R peak point in waveform carries out carrying out two or more R point meter calculating heart rate value.
Generally, heart rate includes following several states: arrhythmia cordis, and the rhythm of the heart of normal person is sinus rhythm, and the rhythm and pace of moving things is balanced,
Frequency is 60~100 times per minute.If exception occur in the origin sinoatrial node or conducting system of heart excitement, the rhythm of the heart just has occurred
It is not normal.
More specifically, after detecting qrs loop, according to the direction of the initial vector of the qrs loop, voltage value and not
Equidirectional changing value carries out heart disease analysis.
Tachycardia: being divided into two class of paroxysmal and non-paroxysmal, and be divided into supraventricular or Ventricular Tachycardia, removes frequency
Fastly, outside irregularity of pulse, how normal the former electrocardiogram form is, and the roomy deformity of the latter's QRS wave is more common in organic heart disease, non-device
Matter heart disease also may occur in which；
Atriomegaly is divided into left and right atrium hypertrophy or double atriomegalies, and ecg characteristics are that P wave is abnormal, is more common in chronic
Heart muscle caused by cor pulmonale, rheumatic mitral stenosis or the various causes of disease thickens, room chamber expands.
Ventricular hypertrophy, is divided into Ventricular hypertrophy or biventricular is loose, and ecg characteristics are that QRS wave is abnormal, is more common in wind
Ventricular muscles caused by moist heart disease, chronic cor pulmonale, congenital heart disease, high blood pressure or the various causes of disease thicken,
Ventricular cavity enlargement.
Sinus arrhythmia, sinus rate are nodal tachycardia more than 100 times per minute, are common in movement or spirit is tight
, fever, hyperthyroidism, anaemia and myocarditis etc..Sinus rate is lower than 60 times per minute for sinus bradycardia, be common in first it is low,
Intracranial hypertension, the elderly and some drugs reaction.The ecg characteristics of sinus arrhythmia are that P-R interphase is abnormal, clinical meaning
Less.
Proiosystole, abbreviation premature beat refer to the heartbeat occurred prior to normal cardiac cycle, often occur long pause later
Referred to as compensatory pause is divided into room, borderline and three kinds of room property.Electrocardiogram Feature is that P wave, QRS wave and ST-T change, and has been had
Full property or incomplete compensatiry pause.Accidental proiosystole is found in normal person, but the ventricular premature beat or formation bigeminy to take place frequently
Rule, trigeminy are more common in a variety of heart diseases；
It flutters and trembles: being divided into atrium and ventricle two major classes.Auricular flutter and trembling are frequency per minute 250~600
Secondary ectopic rhythm, P wave disappear, and instead abnormal " F " wave, is more common in Aged Heart degenerative change, high blood pressure, coronary disease
Disease, pulmonary heart disease, hyperthyroidism etc..Ventricular flutter and trembling belong to malignant arrhythmia, and patient is in peril of one's life, it is necessary to rob against time
It rescues.
The application uses the equipment that lead electrocardiogram is inputted the herein described method of application, will be described by the equipment
Lead electrocardiogram carries out ecg information calculating after being converted to vector ring, obtains the voltage value and and axis of leads of different waves or wave band
The purpose in direction sentence to carry out lesion analysis according to the ecg information that is calculated so that unprofessional user carries out health
It is disconnected.In use, the ecg information being calculated can be stored or be exported with the file of HL7 format.
