ECG ngesikhathi sokukhulelwa kanye nezinye izimo

Electrocardiogram (ECG) kuyinto ukubonisa sokuqhafaza umehluko ezingaba, ezilotshwe phezu komzimba. Le ndlela isisekelo ukuthola izifo yisimiso senhliziyo nemithambo yegazi.
ECG ngesikhathi sokukhulelwa kubalulekile sokunquma conduction nesigci thuthuva ukuthi kungaba ngenxa izilonda isakhi myocardium noma izidakamizwa ukudakwa. Ngaphezu kwalokho, isidumbu sowesifazane, zonke izinqubo ihlelwe kabusha ukudala kwezimo ezifanele ukuthuthukiswa kwempilo entsha.

ECG kakhulu ngesikhathi sokukhulelwa ayishintshi, yebo, uma kungaba ukuthi ukukhulelwa kuphazamisa okuphuma evamile. Ngezinye izikhathi i-ECG kungadala izimpawu eziwumphumela kwegazi hyperkinetic kanye ukufuduka diaphragm futhi wenhliziyo ingaphakathi esifubeni ngenxa yezinguquko bokuphila kubantu besifazane abakhulelwe. Bona zibukeka izinguquko ECG ezilandelayo: shift kwesokunxele of inhliziyo-eksisi kagesi, ukubonakala-isigaba ezimbili, ukunciphisa nokugcina olubushelelezi, kombhala T wokuzuliswa III phambili ejwayelekile nasesifubeni kwesokudla kuholela, ezijulile izinyo Q (kwehle ngo ubambe umoya ukuze umoya) futhi isicaba, ukushintshwa noma prong ezingezinhle R 3 phambili ejwayelekile. I ECG ngesikhathi sokukhulelwa isigqi njalo, itheku, kungadala amabhithi ngaphambi kwesikhathi noma izikhawu ezimfushane nadzheludochnoy tachycardia. Ngo kusaqalwa T ne-Q-P-Q isikhawu obuphelele zingandiswa (ngaphandle becabangela okungale kwalokho kwezinkambiso bokuphila) bese wehlise nge okwandisa isikhathi. Lapho sokukhulelwa kushintsha isilinganiso hormone egazini. Lokhu kuholela ukwehla okuncane ngesikhathi Lokusakaza ishayela kagesi kwi Atria futhi ventricles: i-ECG eqoshiwe ngesikhathi sokukhulelwa ukunciphisa isikhathi QRS eziyinkimbinkimbi, P wave

Phakathi ukulethwa, ikakhulukazi phakathi Kufinyeta, nemizamo nobubanzi P wokuzuliswa PQ isikhawu QRS eziyinkimbinkimbi nokuncipha, kungadala kuka ngakwesokudla inhliziyo-eksisi kagesi. Ngemva kokubeletha, zonke izinguquko inhliziyo zingagcinwa isikhathi eside.

ECG ngokuvamile sisetshenziswa angina pectoris. Livela yalesi sifo kubangela benezincwadi enganele oxygen imisipha yenhliziyo, okuholela ECG izimpawu sengathi ayisibonelo salezi ischaemia esivimba amanzi. Lezi zimo zokuma ST ingxenye shift komugqa isoelectric 1 mm noma ngaphezulu, phezulu - lapho ischemia subepicardial noma inani, phansi - at subendocardial. Lapho unhlangothi futhi kungenzeka ukushintsha T wave ngesikhathi ubuhlungu anginal avele conduction ukukhubazeka nesigci: tachycardia ventricular, ventricular amabhithi ngaphambi kwesikhathi, kungase kube lezivakashi ventricular noma AV block.

Ukuzivocavoca ukuhlolwa ukucindezeleka kuyadingeka ukuhlola ukuzinza esimiso senhliziyo nemithambo yegazi, ngaphezu, zinikeza ithuba ukuhlola yokutakula umsebenzi inhliziyo ngemuva komsebenzi ngokomzimba ngokuhamba kwesikhathi. EKG ngaphansi komthwalo kungaba kwenziwe ngezindlela ezimbili: i-treadmill (treadmill) noma ibhayisikili. Ngaphambi test ibalwa ngamunye ukuze isiguli ileveli enkulu umthwalo, ikhumbula ubulili, ubudala, ukuphakama, isisindo, comorbidities. I oyifunayo umsebenzi kokuqala liyakhula kancane kancane, kuyilapho ngesikhathi esifanayo eqoshiwe electrocardiogram futhi wegazi. Lapho inhliziyo ezithile noma kwenhliziyo rate, ne ukubonakala izinguquko evelele ku ischemic ECG, lapho ubuhlungu lesiguli noma weqise ukukhathala cwaningo kanye nemsebenti lotsintsa umtimba kufanele wayeka. Ngemva kokuma ECG blood pressure uqhubeke ukurekhoda ngisho nemizuzu engu-10. Kufanele kuqashelwe ukuthi ukuziphatha yalezizifundo lihlotshaniswa osindayo enhliziyweni, okungase kuholele ngisho nasezinkingeni stop yayo.
