Deciphering wadnaha ECG

Deciphering ECG kalsoonaan karo lagu ogaan karaa in shaqada wadnaha, sahaminta qalooca la image ee garaaca wadnaha. Electrocardiogram - waxbarasho ee waxqabad ah ee dhaqdhaqaaqa wadnaha muddo waqti go'an. Waxa ay ka tarjumaysaa geedi socodka korontada ee muruqa wadnaha, sida depolarization - farax, iyo repolarization - dib u soo celinta ee unugyada myocardial. Electrocardiogram sameeyaa transthoracic, in uu yahay, iyada oo xabadka, iyadoo la isticmaalayo electrodes kaalinta on dusha maqaarka, la duubo dheeraad ah akhrinta on qalab gaar ah. kelmadaha saxda ah ee ECG siisaa fursad ay si cad u ogaado sax ah iyo, haddii loo baahdo, si loo go'aamiyo daaweynta waqtigii.

ECG ka kooban yahay images of qaybaha ilkaha iyo naadi. Diisan cardiogram - waa meesha ugu ba'an ee khadadka qalooca oo wakiil warqado Roman sifeeyay ka muujinaya soo socda: foosha wadne (P), foosha ventricular (Q, R, S) iyo nasashada ventricular (T). Degmada Afgooye «U» waa yeelsiiyeen iyo dhif duubay. Qaybaha - qaybaha waa xariiq toosan xira ilkaha ku xiga. Ugu muhiimsan waa qoraalka ah ee wadnaha ah in qaybaha PQ iyo ST. Tusaale ahaan, line dusha PQ la aasaasay muddo excitation ee dib u dhac ku atrioventricular (atrioventricular) Guntin ah. Dura - isku dhafan ee ilkaha iyo qaybaha. The dura ugu muhiimsan ECG waa dura PQ iyo S T.

Excitation ee myocardium ee intraventricular qalbiga ku jira waxa lagu gartaa muuqashada ku ECG QRS go'an adag, sababtoo ah ma aha oo kaliya muruqa Atrium weyn, laakiin sidoo kale waxa uu leeyahay septum ku interventricular. adag QRS ugu horeeya ee la qiyaaso size ee ilkaha shaqsi. xarfaha Haddii Ilodanimada ruxruxo ka badan 5 mm, taas waxaa loo qoondeeyey Q, R, iyo S, halkaas oo Ilodanimada inayan ee mooshinka ka yar ee magnitude, waxaa lagu qoray warqad yar q, r ama s. Deciphering ECG ku lug reading saxda ah ee ilkaha. Degmada Afgooye R (r) -, mid kasta waxaa si toos ah kor - ilig wanaagsan iska leh QRS adag. Kasta oo midhona - ilig xun ku yaal R iliga hore, waxaa loo qoray sida Q (q), iyo hoose ee R iliga - waa S iliga (s). Degmada Afgooye Q tilmaamay depolarization ee septum interventricular ah, Wadnaxanuun myocardial, oo waxa ay leedahay lagu qiimeeyay qoto dheer la dheereeyey. Degmada Afgooye R muujinaysaa depolarization ee bulk of myocardium ah, iyo S muujinaysaa qaybaha ilkaha ee hawsha wadne ee septum interventricular ah.

Deciphering wadnaha ECG ka kooban cilmi reading shan dhibcood:

1. Falanqaynta of garaaca wadnaha iyo tabinta wadnaha. Falanqaynta Tani waxay u muuqataa garaaca wadnaha qiyaasta periodicity, go'aaminta heerka garaaca wadnahaaga (HR), abuuritaanka ilo excitation iyo tabinta ku caan;

2. Go'aaminta dhidibka koronto ee la karsado wadnaha;

3. Study P ruxruxo wadne-;

4. waxbarasho ee QRST adag;

5. Baadhista ECG Gunaanad.

Deciphering ECG caafimaad qalbiga qofka ku bilaabmaa la ruxruxo wadne-gaaban (ab), isbadalka in awoodda intraventricular ah dhiig galaan wakhtiga systole - foosha wadne. In la ruxruxo electrocardiogram this shisheeyaa P-ruxruxo ka dibna kor u kaco, oo muujinaya systole ventricular. Tani waxay u kaca uga yaacday (b-d) socota Q iliga iyo guuro meel siman (D-e). Muddada nasashada ee ventricle bidix iyo hoos u cadaadiska dhexdeeda ah, xariiqa qallooca ayaa u soo maratay hoos u dhaco (e-g), dhibic g dhiganta la furitaanka waalka mitral ah iyo rush dhiigga galay intraventricular ah. In Duke of dhimayo waa hal dhibic u dhigma danab ee waalka mitral ah, iyo hal dhibic ka mid ah f, oo u dhiganta xiritaanka waalka aortic. Ka dib markii la ruxruxo foomamka la ruxruxo systolic ventricular buux (g-h) iyo hakin ay content (k-a). Raacay by wareegga ECG celiyaan qalbi caafimaad qaba aadanaha.
