Deciphering ECG zuciya

Deciphering ECG iya dogara gane munanan a cardiac aiki, binciko kwana tare da image na zuciya rate. Electrocardiogram - nazarin aiki na cardiac aiki ga wani lokaci. Yana nuna lantarki matakai a cikin zuciya tsoka, kamar depolarization - tashin hankali, da kuma repolarization - na maido da tsokar Kwayoyin. Electrocardiogram yi transthoracic, cewa shi ne, ta hanyar da kirji, ta amfani da wayoyin sanya, a cikin fata surface, tare da kara rikodi na karatu a kan na musamman na'urar. Proper dikodi mai na ECG samar da wata dama ga fili kafa wani cikakken bincike da kuma, idan ya cancanta, domin sanin dace magani.

ECG kunshi hotunan hakora segments da ramummuka. Dents cardiogram - shi ne cikin matsananci nufi da kwana Lines wanda wakiltar Roman haruffa characterizing da wadannan alamomi: atrial ƙanƙancewa (P), na ramin zuciya contractions (Q, R, S) da kuma na ramin zuciya shakatawa (T). Barb «U» ne fickle da ba safai rubuta. Segments - segments ne a mike layin a haɗa da m hakora. A mafi muhimmanci shi ne kwafi na wani electrocardiogram a cikin PQ kuma ST segments. Alal misali, PQ kwane-kwane line kafa a cikin zumudi lokaci na bata lokaci a cikin atrioventricular (atrioventricular) kumburi. Jinkiri - mai hade da hakora da kuma segments. A mafi muhimmanci ECG jinkiri ne jinkiri PQ da Q- T.

Zumudi a cikin myocardium na zuciya ventricles ne halin da bayyanar a kan ECG QRS hadaddun sa, domin shi ne ba kawai m atrium tsoka, amma kuma yana da interventricular septum. A QRS hadaddun farko kimanta girman da mutum hakora. Idan kalaman mawadãta wuce 5 mm, wannan da aka sanya babban birnin kasar haruffa Q, R, kuma S, inda amplitude na motsi ne karami a girma, shi ana wajabta kananan harafi q, r ko s. Deciphering ECG unshi da daidai karatu da hakora. Barb R (r) -, kowane ne directed zuwa sama - m hakori nasa ne da hadaddun QRS. Duk wani downward - korau hakori ayi a gaban hakori R, an wajabta, kamar yadda Q (q), kuma da nisa da tushe na hakori R - ne da hakori S (s). Barb Q characterizes depolarization na interventricular septum, tsokar zuciya infarction, kuma shi yana da wani Extended zurfin darajar. Barb R nuna depolarization na da girma daga cikin myocardium, kuma S nuna da hakori sassan na atrial aiki na interventricular septum.

Deciphering ECG zuciya kunshi wani biyar-aya karatu da bincike:

1. A bincike na zuciya rate da cardiac madugu. Wannan bincike kwakwalwa periodicity kimanta zuciya kudi, tabbatar da dalilin da zuciya rate (HR), da kafa da zumudi tushen da kuma madugu halayyar.

2. Tabbatar da dalilin da lantarki axis na zuciya hatsaisai.

3. Nazarin atrial kalaman P.

4. A binciken da na hadaddun QRST.

5. Kammalawa ECG bincikowa.

Deciphering ECG zuciya lafiya mutum fara da wani gajeren atrial kalaman (ab), nuna da canji a cikin damar da ventricles da jini shigar lokacin systole - atrial ƙanƙancewa. A wannan electrocardiogram kalaman ne bayan da P-kalaman sa'an nan tasu ya dinga tashi, da nuna na ramin zuciya systole. Wannan m Yunƙurin (b-d) ya bi hakori Q da kuma motsa su da kwance matsayi (D-e). A shakatawa lokaci na hagu ventricle da matsa lamba akan rage a cikinta, da kwana sharply dama saukar (e-g), g batu yayi daidai da bude daga cikin mitral bawul da kara na jini a cikin ventricles. A cikin farkawa daga cikin saukarwa ne wani batu da ya dace ga irin ƙarfin lantarki na da mitral bawul, da kuma batu na f, m ga ƙulli daga cikin aortic bawul. Bayan da systolic kalaman siffofin na ramin zuciya cika kalaman (g-h) da kuma rage abun (k-a). Bi ta sake ECG sake zagayowar da lafiya zuciyar ɗan adam.
