Yintoni esetyenziswayo?
I-electrocardiogram, okanye i-ECG, uvavanyo oluqhelekileyo olusetyenziswa oogqirha ukuvavanya imeko yentliziyo. I-ECG isetyenziswe kakhulu ngenxa yokuba inokukhenkcelela kwiimeko ezahlukeneyo zentliziyo, imishini ye-ECG ifumaneke kwiindawo ezininzi zonyango, kwaye ukuvavanywa kulula ukwenza, kubaluleke kakhulu ukuba kungabi nengozi, kwaye kungabibizi.
I-ECG yenziwe njani?
Umntu one-ECG ehamba phambili ye-12 ehamba phambili uya kulala kwitafile yeemviwo kunye nesifuba sakhe sibonakala.
(Abasetyhini banokugcina iibras zabo ngokubanzi.) I-electrode yeshumi (okanye iikholeji) ihlanganiswe - enye ingalo nomlenze, kunye nesithandathu kwisifuba. .
Ama-electrode asetyenziselwa ukurekhoda umbane wentliziyo. Ezi zimpawu zombane zithunyelwa kumshini we-ECG, apho zicutshungulwa khona, kwaye ziprintwe njenge-"ECG tracing". Uvavanyo lwe-ECG lithatha ngaphantsi kwemizuzu emihlanu ukwenza.
Uluhlu Luni lwe-ECG lukhangeleka?
Umfanekiso kweli phepha ubonisa i- ECG evamile , evamile . Izibonakaliso zombane eziveliswe kwii-electrode ezilishumi ziye zaqhutyelwa "kwiimbono" ezingu-12 zomsebenzi wombane - oko kuthiwa yi-ECG ehamba phambili. Ngokuhlolisisa naziphi na izinto ezingaqhelekanga kwi-ECG, kwaye ngokuqwalasela oku kubangela ukuba okungaqhelekanga kubonakale kukho, ugqirha unokufumana amanqaku amaninzi ebalulekileyo malunga nesimo senhliziyo.
Ziziphi iinkcukacha eziza kufundiswa kwi-ECG?
Ukusuka ekulandeleni i-ECG, le nkcazelo elandelayo inokumiselwa:
- izinga lentliziyo
- ingaba kukho nayiphi na intliziyo ye-arrhythmias , ezinjengeenkomfa zangaphambili ze-ventricular okanye i-fibrillation ye-atrial .
- ingaba kukho "ukungaqhelekanga kokuqhuba" (ukungavumelekanga kwindlela umtshini wombane usasazeka ngayo yonke intliziyo), njengesiqithi segatsha .
- ingaba kukho nawuphi na uphawu loqhubela phambili okanye ngaphambili kwe-myocardial infarction
- ingaba kukho izibonakaliso ezingaphezulu kwe- coronary artery (CAD)
- ingaba isisu senhliziyo siye saqina ngokungaqhelekanga, njengokwimeko ye -cardiomyopathy ye-hypertrophic .
- ingaba kukho iimpawu zokungaqhelekanga kombane, ezifana ne- Brugada syndrome .
Zonke ezi zinto zibaluleke kakhulu. Ngelixa i-ECG ingenza i-diagnostic ecacileyo kwiimeko ezithile zentliziyo (njenge-cardiac arrhythmia), kudla ngokuba luncedo njengoluvavanyo lokuhlola. Ukungaqhelekanga okubonakalayo kwi-ECG kufuneka kulandelelwe uvavanyo oluchanekileyo ukwenzela ukuba kwenziwe ukuxilongwa ngokucacileyo. Ngokomzekelo, Ukuba i-ECG ibonisa i-CAD enokwenzeka, uvavanyo loxinzelelo okanye ukunyanyiswa komzimba kungadingeka . Ukuba kubonakala i-hypertrophy ye-ventricular, i- echocardiogram idla ngokufunekayo ukujonga isifo senhliziyo se-valvular (njenge- aortic stenosis ), okanye ezinye izinto ezingaqhelekanga.
Ziziphi iimida ze-ECG?
- I-ECG ibonisa izinga lentliziyo kunye nesingqimba kuphela ngemizuzwana embalwa kuthatha ukurekhoda i-ECG. Ukuba i-arrhythmia ephakathi ikhunjulwa, ukubeka iliso lokubambisana kunokufuneka.
- I-ECG isinokuqhelekileyo ibe yinto eqhelekileyo okanye eqhelekileyo kwizigulane ezine-CAD ezingafumanekiyo okanye ezinye iintlobo zesifo senhliziyo (iziphumo ezingalunganga.)
- Uninzi "okungaqhelekanga" olubonakala kwi-ECG luya kuba lukhulu lwezokwelapha emva kokuvavanywa okucwangcisiweyo kwenziwa (iziphumo ezimbi).
Xa kufuneka ube ne-ECG?
Kunengqiqo ukuba ugqirha wakho enze i-ECG okokuqala ekubonayo, njengesifundo esisezantsi. Olu vavanyo lunokuthelekiswa nokuvavanywa kamva ukuze ubone ukuba kukho utshintsho olwenzekile.
Kunengqiqo nokwenza i-ECG njengenxalenye yonyango lonyango lwenyanga xa unesifo senhliziyo esikhathini esidlulileyo, okanye ukuba unobungozi obukhulu bokugula kweengqondo . Nangona kunjalo, ukuba unempilweni ngokupheleleyo kwaye ungenayo ingozi enkulu, ezininzi iingcali azicebisi kwakhona "rhoqo" i-ECG yonyaka.
