Achiongorora zvaive ECG mwoyo

Achiongorora zvaive ECG anogona yakavimbika kuziva abnormalities mu cardiac basa, ichitsvaka munyonga pamwe mufananidzo kwemwoyo. Electrocardiogram - kudzidza webasa cardiac basa kuti imwe nguva. Zvinoratidza zvemagetsi pezvakaitwa mumwoyo tsandanyama, akadai depolarization - mafaro, uye repolarization - kudzorerwa masero myocardial. Electrocardiogram akaita transthoracic, kureva, kuburikidza mubhokisi, vachishandisa electrodes akaisa paganda pamusoro, mimwe zvokurekodhwa kuverengwa iri mudziyo unokosha. decoding zvakakodzera ECG zvinopa mukana kumisa zvakajeka kuongororwa zvakarurama uye, kana zvakakodzera, kuti kuona nenguva kurapwa.

ECG rine mifananidzo mazino zvikamu uye cheap car insurance. Netsaona cardiogram - ndiro yokunyanyisa pfungwa munyonga mitsetse inomiririra tsamba Roman zvinoratidza zvinotevera zvairatidza: atrial marwadzo (P), ventricular sunga (Q, R, S) uye ventricular kutandara (T). Barb «U» ndiye chinji uye kashoma akanyorwa. Zvikamu - zvikamu chinhu yakarurama mutsetse unobva pedyo mazino. Chinonyanya kukosha ndiyo inopangidza ane unonzi, electrocardiograph muna PQ uye ST zvikamu. Somuenzaniso, PQ gandiwa mutsetse yakaumbwa muna excitation nguva kunonoka ari atrioventricular (atrioventricular) raiva pedyo nebundu. Zvikamu - mubatanidzwa mazino uye zvikamu. Chinonyanya kukosha ECG zvikamu zviri zvikamu PQ uye Q- T.

Excitation ari myocardium mwoyo ventricles kunoratidzwa chitarisiko pamusoro ECG QRS kunzwisisa yakatarwa, nekuti hazvina chete hombe atrium tsandanyama, asi anewo interventricular septum. The QRS zvakaoma kutanga kufungidzira kukura wacho kwemeno. Kana chinozunguzirwa amplitude kwazvo 5 neMM, izvi akasarudzwa mavara makuru Q, R, uye S, uko amplitude inofamba iri seduku nokukura, chichitsveneswa ushandiswe tsamba duku Q, R kana s. Achiongorora zvaive ECG kunosanganisira kuverengwa kwakarurama kwemeno. Barb R (R) - mumwe chinotungamirwa mudenga - akanaka zino ndohwaJehovha dzakaoma QRS. Chero pasi - zino kunaka rakamiswa pamberi zino R, iri ushandiswe sezvo Q (q), uye nomurwizi of zino R - ndiye zino S (s). Barb Q inechirevo depolarization ari interventricular septum, myocardial infarction, uye ane yakareba udzamu kukosha. Barb R inoratidza depolarization pakati unorema kubva myocardium, uye S rinoratidza zino zvikamu atrial basa interventricular septum.

Achiongorora zvaive ECG mwoyo ine shanu-pfungwa tsvakurudzo kuverenga:

1. Kuongororwa nomwoyo exchange uye cardiac conduction. Ongororo iyi achipfeka periodicity kufungidzira kwemwoyo, Kutsunga kwemwoyo (HR), kugadzwa excitation panobva uye conduction mamirire;

2. Kutsunga of zvemagetsi akabatana mumoyo pulses;

3. Kudzidza atrial chinozunguzirwa P;

4. Kudzidza kunzwisisa QRST;

5. Mhedziso ECG Diagnostics.

Achiongorora zvaive ECG utano mwoyo munhu chinotanga pfupi atrial chinozunguzirwa (AB), tichiratidza kuchinja vanokwanisa pakati ventricles neropa kupinda nguva systole - atrial marwadzo. In ichi unonzi, electrocardiograph wave mhiri P-wave uye ipapo achikwira, achiratidza ventricular systole. Izvi pamawere vosimba (b-d) kunotevera zino Q uye kunoita kuti chinjikira nzvimbo (D-e). The kutandara Nguva ventricle rworuboshwe uye kumanikidza rutapudzo zvirimo, munyonga rinooneka anowira pasi (e-g), g pfungwa zvachinotarisana Panovhurwa ari mitral vharuvhu uye nhokwe ropa mukati ventricles. In pekufa rutapudzo ndiyo pfungwa kuti rinoenderana voltage pakati ari mitral vharuvhu, uye pfungwa f, zvakafanana kuvhara zviri kutsemuka vharuvhu. Mushure systolic chinozunguzirwa siyana ventricular zvekupfakira chinozunguzirwa (g-h) uye kuderedza kugutsikana kwavo (K-a). Uchiteverwa wodzokorora ECG kutenderera mwoyo utano hwevanhu.
