I-Electrocardiogram

I-electrocardiogram (ECG) isivivinyo esiqopha umsebenzi kagesi wenhliziyo.

Uzocelwa ukuba ulale phansi. Umhlinzeki wezokunakekelwa kwempilo uzohlanza izindawo eziningana ezingalweni zakho, emilenzeni, nasesifubeni, abese enamathisela amabala amancane abizwa ngama-electrode kulezo zindawo. Kungadingeka ukushefa noma ukunqamula ezinye izinwele ukuze amachashazi anamathele esikhunjeni. Inani lezimagqabhagqabha ezisetshenzisiwe lingahluka.

Amachashazi axhunywe ngezintambo emshinini oguqula amasiginali kagesi enhliziyo abe imigqa yamagagasi, evame ukuphrintwa ephepheni. Udokotela ubuyekeza imiphumela yokuhlolwa.

Uzodinga ukuhlala unganyakazi ngesikhathi senqubo. Umhlinzeki futhi angakucela ukuthi ubambe umoya wakho imizuzwana embalwa njengoba ukuhlolwa kwenziwa.

Kubalulekile ukukhululeka futhi ufudumale ngesikhathi sokuqoshwa kwe-ECG ngoba noma yikuphi ukunyakaza, kufaka phakathi ukuqhaqhazela, kungashintsha imiphumela.

Kwesinye isikhathi lokhu kuhlolwa kwenziwa ngenkathi uzivocavoca noma unengcindezi yokukhanya ukuze ubheke izinguquko enhliziyweni. Lolu hlobo lwe-ECG luvame ukubizwa ngokuthi yi-test test.

Qiniseka ukuthi umhlinzeki wakho uyazi ngayo yonke imithi oyiphuzayo. Eminye imishanguzo ingaphazamisa imiphumela yokuhlolwa.

UNGAVAKALISI ukuzivocavoca noma uphuze amanzi abandayo ngokushesha ngaphambi kwe-ECG ngoba lezi zenzo zingadala imiphumela engeyona.

I-ECG ayibuhlungu. Awukho ugesi othunyelwa ngomzimba. Ama-electrode angazizwa ebanda lapho eqala ukusetshenziswa. Ezimweni ezingavamile, abanye abantu bangaba nokuqubuka noma ukucasuka lapho kubekwe khona iziqeshana.

I-ECG isetshenziselwa ukukala:

• Noma yimuphi umonakalo enhliziyweni
• Ishesha kangakanani inhliziyo yakho nokuthi ishaya ngokujwayelekile
• Imiphumela yezidakamizwa noma amadivayisi asetshenziselwa ukulawula inhliziyo (njenge-pacemaker)
• Usayizi nokuma kwamagumbi enhliziyo yakho

I-ECG imvamisa ukuhlolwa kokuqala ukwenziwa ukuthola ukuthi umuntu unesifo senhliziyo yini. Umhlinzeki wakho anga-oda lokhu kuhlolwa uma:

• Unobuhlungu besifuba noma ukushaya kwenhliziyo
• Uhlelelwe ukuhlinzwa
• Uke waba nezinkinga zenhliziyo esikhathini esedlule
• Unomlando oqinile wesifo senhliziyo emndenini

Imiphumela ejwayelekile yokuhlolwa ifaka phakathi:

• Ukushaya kwenhliziyo: ukushaya okungu-60 kuya ku-100 ngomzuzu
• Isigqi senhliziyo: Kuyavumelana futhi kuyalingana

Imiphumela engajwayelekile ye-ECG ingaba uphawu lokuthi:

• Ukulimala noma izinguquko ezicutshini zenhliziyo
• Izinguquko kwinani lama-electrolyte (njenge-potassium ne-calcium) egazini
• Isici senhliziyo esizalwe naso
• Ukwandiswa kwenhliziyo
• Uketshezi noma ukuvuvukala esikhwameni esizungeze inhliziyo
• Ukuvuvukala kwenhliziyo (myocarditis)
• Isifo senhliziyo esedlule noma samanje
• Ukunikezwa kwegazi okuncane emithanjeni yenhliziyo
• Isigqi senhliziyo esingajwayelekile (arrhythmias)

Ezinye izinkinga zenhliziyo ezingadala ushintsho esivivinyweni se-ECG zifaka:

• I-Atrial fibrillation / i-flutter
• Isifo senhliziyo
• Ukwehluleka kwenhliziyo
• I-tachycardia ye-atrial eminingi
• I-paroxysmal supraventricular tachycardia
• Isifo se-sinus syndrome
• Isifo se-Wolff-Parkinson-White

Azikho izingozi.

Ukunemba kwe-ECG kuya ngesimo esivivinywayo. Inkinga yenhliziyo ingahle ingabonakali njalo ku-ECG. Ezinye izimo zenhliziyo azikaze zenze ushintsho oluthile lwe-ECG.
