Ziqonde ECG Intliziyo

Kuqondwe ECG uyakwazi ngokuthembekileyo ukungaphili kumsebenzi kwentliziyo, ukuhlola kwigophe kunye nomfanekiso izinga kwentliziyo. Electrocardiogram - isifundo umsebenzi yomsebenzi kwentliziyo kangangexesha elithile. Oku kubonisa iinkqubo zombane imisipha intliziyo, ezifana depolarization - uchulumanco, kunye repolarization - ukubuyiselwa iiseli engabalulekanga. Electrocardiogram enze transthoracic, oko kukuthi, ngenxa esifubeni, esebenzisa electrode kubekwa phezu eluswini, kunye ushicilelo olunye ufundo kwisixhobo okhethekileyo. ekufundeni eyiyo ECG kunika ithuba lokuba ukuseka ngokucacileyo ukuxilongwa kwaye, ukuba kuyimfuneko, ukugqiba unyango kwangethuba.

ECG anemifanekiso uziziqwempu amazinyo kunye Azisekho. Nge- cardiogram - eyona ngongoma esibi imigca curve nenika oonobumba yaseRoma eziphawula iziboniso zilandelayo: ucutheko atrial (P), izishunqulelo ventricular (Q, R, S) kunye ventricular nokuphumla (T). Barb «U» luyinto zaza zarekhodwa kunqabile. Ezi ziqwempu - ziqwempu yi umgca othe ngqo oqhagamshelanisa amazinyo ezikufutshane. Eyona nto ibalulekileyo kukuba okotshiweyo se electrocardiogram kwi PQ kunye ST komsindo. Umzekelo, PQ umgca nentaba abunjwe kwithuba excitation of ukulibaziseka atrioventricular (atrioventricular) node. Amathuba - indibanisela amazinyo kunye namacandelo. Amathuba ibalulekileyo ECG na ekhefu PQ kunye Q- T.

Excitation kwi myocardium le ventricles intliziyo luphawulwa ukuvela ECG QRS iseti enzima, kuba ayikho kuphela intendelezo kwezihlunu enkulu, kodwa kumele ekudibaneni interventricular. I QRS complex kuqala ukuqikelela ubungakanani kwamazinyo ngamnye. iileta Ukuba wave awo udlula 5 mm, oku ngokwesikhundla capital Q, R, kunye S, apho awo sesindululo incincane e lilodwa, ngaba emiselweyo ileta encinane q, r okanye s. Ziqonde ECG ibandakanya ukufunda elichanekileyo kwamazinyo. Barb R (r) -, nganye ijoliswe phezulu - Izinyo HIV bobabo ukuya QRS ezintsonkothileyo. Nayiphi kwehle - Izinyo elibi ime phambi izinyo R, emiselwe njengokuba Q (q), kunye emazantsi izinyo R - yeyona S izinyo (s). Barb Q ephawula depolarization ye ekudibaneni interventricular, iposi engabalulekanga, kwaye anexabiso kubunzulu elide. Barb R ubonisa depolarization ye isambuku myocardium, kunye S ibonisa amacandelo izinyo umsebenzi atrial ye ekudibaneni interventricular.

Ziqonde ECG intliziyo iquka uphando ukufunda ingongoma ezintlanu-:

1. Uhlalutyo of izinga lentliziyo kunye Uhanjiso intliziyo. Olu hlalutyo luthatha izinga lentliziyo periodicity uqikelelo, ukumiselwa izinga kwentliziyo (HR), ukumiselwa umthombo excitation kunye Uhanjiso iimpawu;

2. Ukumiselwa esqwini wombane pulses intliziyo;

3. Study wave atrial P;

4. Isifundo QRST kuntsonkothileyo;

5. uxilongo Isiphelo ECG.

Ziqonde ECG Intliziyo obusempilweni umntu iqala nge wave elifutshane atrial (ab), ebonisa ukuba utshintsho kwamandla ventricles igazi ngokungenisa ixesha systole - nokuncipha atrial. Kule wave electrocardiogram eliphesheya P-yomtshangatshangiso koko onyukayo, ebonisa systole ventricular. Le ukunyuka (b-d) lulandela izinyo Q kwaye wenza ukuba ngokuxwesileyo (D-e). Ithuba lokuphumla le ventricle yasekhohlo kunye nokunciphisa ingcinezelo kuyo, igophe kabukhali uwela phantsi (e-g), g indawo liyangqinelana ukuvulwa ivelufa mitral kunye hawu igazi kungena ventricles. Emva kwalo Ukwehla ingongoma oluhambisana lombane ivelufa mitral, yaye kwinqanaba f, ulungelelene ukuvalwa ivalve aortic. Emva kokuba iifom iSystolic wave ventricular ukuzaliswa ngumtshangatshangiso (g-h) wehlise isiqulatho yabo (k-a). Kulandele umjikelo phinda ECG ngentliziyo yomntu esempilweni.
