Ungawusebenzisa kanjani umshini we-ECG

Ngenxa yobuchwepheshe bayo bokuxilonga obuvuthiwe, ukwethembeka, ukusebenza okulula, intengo emaphakathi, futhi akukho monakalo ezigulini, umshini we-electrocardiogram usuphenduke elinye lamathuluzi okuxilonga ajwayelekile embhedeni.Njengoba ububanzi bokufaka isicelo buqhubeka nokwanda, sekungenye yezivivinyo ezinhlanu ezijwayelekile “zegazi, umchamo, indle, i-imaging, kanye ne-electrocardiogram”, ikakhulukazi ezifweni ezithile zenhliziyo njenge: isifo senhliziyo esingamahlalakhona, isifo senhliziyo esibuhlungu, i-Myocarditis. , i-pericarditis, i-pulmonary embolism kanye ne-arrhythmia inenani lokuxilonga.Uyazi ukuthi isetshenziswa kanjani.

Ukuze usebenzise umshini we-ECG (Electrocardiogram), landela lezi zinyathelo ezijwayelekile:

1. Lungiselela isiguli: Qinisekisa ukuthi isiguli sisesimweni esihle futhi siveze indawo yesifuba saso.Bangase badinge ukukhipha izingubo noma ubucwebe obungase buphazamise ukubekwa kwama-electrode.

2. Amandla emshinini: Vula umshini we-ECG futhi uwuvumele ukuthi uqedele inqubo yawo yokuqalisa.Qiniseka ukuthi umshini usebenza ngendlela efanele nokuthi izinto ezidingekayo, njengama-electrode e-ECG nejeli yokuqhuba, ziyatholakala.

3.Namathisela ama-electrode: Beka ama-electrode e-ECG ezindaweni ezithile zomzimba wesiguli njengoba uyalelwe umkhiqizi womshini noma uchwepheshe wezokunakekelwa kwempilo.Ngokuvamile, ama-electrode abekwa esifubeni, ezingalweni nasemilenzeni.Landela ikhodi yombala kuma-electrode ukuze uqinisekise ukubekwa okulungile.Nazi ezinye izindlela ezijwayelekile ze-ECG : imikhondo yesifuba, izitho zomzimba, nemikhondo ejwayelekile.

1) Indlela yokuxhuma umthofu wesitho: Umlenze ongaphezulu kwesokudla - umugqa obomvu, umlenze ongaphezulu kwesokunxele - umugqa ophuzi, umlenze ophansi wesobunxele - umugqa oluhlaza, umlenze ophansi wesokudla - umugqa omnyama

2) Indlela yokuxhuma isifuba sokuhola:

I-V1, indawo yesi-4 ye-intercostal emngceleni ongakwesokudla we-sternum.

I-V2, indawo yesine ye-intercostal emngceleni wesokunxele we-sternum.

I-midpoint yomugqa oxhuma i-V3, i-V2 ne-V4.

I-V4, ukuphambana komugqa wesokunxele we-midclavicular kanye nesikhala sesihlanu se-intercostal.

I-V5, umugqa we-axillary ongaphambili kwesokunxele usezingeni elifanayo ne-V4.

I-V6, umugqa wesobunxele we-midaxillary usezingeni elifanayo ne-V4.

I-V7, umugqa we-axillary wangakwesokunxele usezingeni elifanayo ne-V4.

I-V8, umugqa wesikali kwesokunxele usezingeni elifanayo ne-V4.

I-V9, umugqa we-paraspinal kwesokunxele usezingeni elifanayo ne-V4.

(Izintambo ze-V1-V6 ngokulandelana kombala: obomvu, ophuzi, oluhlaza okotshani, onsundu, omnyama, onsomi)

4. Lungisa isikhumba: Uma kudingekile, hlanza isikhumba sesiguli ngephedi lotshwala noma isixazululo esifanayo sokuhlanza ukuze ususe amafutha, ukungcola, noma umjuluko.Lokhu kusiza ukuthuthukisa ikhwalithi yesiginali ye-ECG.

5. Faka ijeli yokuqondisa (uma kudingeka): Amanye ama-electrode angase adinge ukuthi kufakwe ijeli yokuqondisa ukuze kuthuthukiswe ukuthintana kukagesi nesikhumba.Landela imiyalelo ehlinzekwe ngama-electrode noma bheka imanuwali yomsebenzisi womshini ukuze usebenzise ijeli efanele.

6. Xhuma ama-electrode emshinini: Namathisela i-electrode eholela kumachweba ahambisanayo emshinini we-ECG.Qinisekisa ukuxhumana okuphephile ukuze ugweme ama-artifact noma ukuphazamiseka phakathi nokurekhoda.

7. Qala ukurekhoda: Uma ama-electrode enamathiselwe kahle, qalisa umsebenzi wokuqopha emshinini we-ECG.Landela imiyalo noma imiyalelo enikezwe isixhumi esibonakalayo somshini.

8. Gada okurekhodiwe: Bheka i-waveform ye-ECG eboniswe esikrinini somshini.Qinisekisa ukuthi ikhwalithi yesiginali yinhle, inamagagasi acacile futhi ahlukile.Uma kunesidingo, lungisa ukubekwa kwe-electrode noma uhlole ukuxhumana okuxekethile.

9. Qeda ukurekhoda: Uma isikhathi sokurekhoda esifiselekayo sesifinyelelwe noma njengoba siyalwe uchwepheshe wezokunakekelwa kwempilo, misa umsebenzi wokurekhoda emshinini.

10. Buyekeza futhi uhumushe i-ECG: I-ECG erekhodiwe izovezwa njengegrafu noma i-waveform esikrinini somshini.Kubalulekile ukuqaphela ukuthi ukuhumusha i-ECG kudinga ubuchwepheshe bezokwelapha.Xhumana nochwepheshe bezempilo oqeqeshiwe, njengodokotela noma udokotela wenhliziyo, ukuze ahlaziye i-ECG futhi ahumushe imiphumela ngokunembile.
