Electrocardiogram

I-electrocardiogram (ECG) luvavanyo olurekhoda umsebenzi wombane wentliziyo.

Uya kucelwa ukuba ulale phantsi. Umboneleli wezempilo uyakucoca iindawo ezininzi ezingalweni, emilenzeni, nasesifubeni, emva koko ke uya kuthi anamathisele amabala amancinci abizwa ngokuba zii-electrode kwezo ndawo. Kunokuba yimfuneko ukucheba okanye ukucofa ezinye iinwele ukuze amabala anamathele eluswini. Inani leepatches ezisetyenzisiweyo lingahluka.

Amachaphaza aqhagamshelwe ziingcingo kumatshini ojika imiqondiso yombane yentliziyo ibe yimigca ye-wavy, edla ngokuprintwa ephepheni. Ugqirha uphonononge iziphumo zovavanyo.

Uya kudinga ukuhlala uzolile ngexesha lenkqubo. Umboneleli unokucela ukuba ubambe umphefumlo wakho imizuzwana embalwa njengoko uvavanyo lusenziwa.

Kubalulekile ukuba ukhululeke kwaye ufudumale ngexesha lokurekhodwa kwe-ECG kuba nayiphi na intshukumo, kubandakanya ukungcangcazela, inokutshintsha iziphumo.

Ngamanye amaxesha olu vavanyo lwenziwa ngelixa usenza umthambo okanye uphantsi koxinzelelo lokukhanya ukujonga utshintsho entliziyweni. Olu hlobo lwe-ECG lubizwa ngokuba luvavanyo loxinzelelo.

Qinisekisa ukuba umboneleli wakho uyazi ngawo onke amayeza owathathayo. Amanye amachiza anokuphazamisa iziphumo zovavanyo.

SUKUYENZA umthambo okanye usele amanzi abandayo kwangoko phambi kwe-ECG kuba ezi zinto zinokubangela iziphumo ezingezizo.

I-ECG ayinazintlungu. Akukho mbane uthunyelwe ngomzimba. Ii-electrode zinokuziva zibanda xa zisetyenziswa okokuqala. Kwiimeko ezinqabileyo, abanye abantu banokuphuhlisa irhashalala okanye ukucaphuka apho bekubekwe khona iipatches.

I-ECG isetyenziselwa ukulinganisa:

• Nawuphi na umonakalo entliziyweni
• Ikhawuleza kangakanani ukubetha kwentliziyo yakho nokuba ibetha ngesiqhelo na
• Iziphumo zeziyobisi okanye izixhobo ezisetyenziselwa ukulawula intliziyo (njenge pacemaker)
• Ubungakanani kunye nokuma kwamagumbi akho entliziyo

I-ECG ihlala iluvavanyo lokuqala ukwenziwa ukufumanisa ukuba ingaba umntu unesifo sentliziyo na. Umboneleli wakho unoku-odola olu vavanyo ukuba:

• Unentlungu esifubeni okanye ukubetha
• Ucwangciselwe utyando
• Uneengxaki zentliziyo kwixa elidlulileyo
• Unembali eqinileyo yesifo sentliziyo kusapho

Iziphumo zovavanyo eziqhelekileyo zihlala zibandakanya:

• Inqanaba lentliziyo: i-60 ukuya kwi-100 beats ngomzuzu
• Isingqisho sentliziyo: Iyahambelana kwaye iyalingana

Iziphumo ze-ECG ezingaqhelekanga zinokuba luphawu loku:

• Ukonakala okanye utshintsho kwimisipha yentliziyo
• Utshintsho kwinani lee-electrolyte (ezinje nge potassium kunye ne calcium) egazini
• Isiphene sentliziyo
• Ukwandiswa kwentliziyo
• Ulwelo okanye ukudumba engxoweni ejikeleze intliziyo
• Ukudumba kwentliziyo (myocarditis)
• Ukuhlaselwa kwentliziyo kwangaphambili okanye kwangoku
• Ukunikezelwa kwegazi okungalunganga kwimithambo yentliziyo
• Iingqungquthela zentliziyo engaqhelekanga (arrhythmias)

Ezinye iingxaki zentliziyo ezinokukhokelela kutshintsho kuvavanyo lwe-ECG zibandakanya:

• I-Atrial fibrillation / iflutter
• Ukuhlaselwa yintliziyo
• Ukumelwa yintliziyo
• I-tachycardia yemithambo emininzi
• I-Paroxysmal supraventricular tachycardia
• Isifo sesinus
• Iswekile yeWolff-Parkinson-White

Akukho bungozi.

Ukuchaneka kwe-ECG kuxhomekeke kwimeko yokuvavanywa. Ingxaki yentliziyo ayinakuhlala ibonakala kwi-ECG. Ezinye iimeko zentliziyo azize zivelise naluphi na utshintsho oluthile lwe-ECG.
