Sokuqonda ECG - indlela enokwethenjelwa kakhulu ukuxilongwa

Cardiogram ephrintiwe kudivayisi esikhethekile ifilimu enezithombe noma iphepha. I grafu ikhombisa okwenzeka enhliziyweni. Zonke isifo senhliziyo ngomshini ECG. Ungayisebenzisa ukuba bagcine umsebenzi isimiso sokujikeleza kwegazi, lo njalo futhi imvamisa we ukushaya kwenhliziyo, ukukhomba Ukwehla futhi ukuvinjelwa kwe-conductivity igazi ufunde ukuthi yimiphi izicubu zenhliziyo hypoxia futhi ukucacisa ngaphambilini sidluliselwe useshonile futhi inhliziyo ukuhlaselwa.

Ngaphezu kwalokho, emagama of ECG ukunquma ijubane ukushaya kwenhliziyo (ishayela). Norma omdala nenhliziyo enempilo uphumule ukuze 60-80 ishaya ngomzuzu. Lokhu kwenza kube lula ukubona ukuthi ezinjengokungcoliswa kulokolokoza futhi flutter. Lapho nokucwayiza ishayela ongafinyelela 600 ngomzuzu, futhi Flutter - 400.

ECG yokusebenza isimiso ukuthi cardiograph eqoshiwe umugqa voltage, okuyinto kudlule inhliziyo zawo wonke umzimba. Amapharamitha ngala magagasi njani isimo senhliziyo. Njenganoma yimuphi kokungabaza, cardiowaves unayo i amplitude nokubaluleka, futhi emagama of ECG wukuqinisekisa ukuthi lezi yizinkomba ibalwa nobuningi namandla ukuphumula esishubile imisipha yenhliziyo. On lezi idatha kusekelwe uphethwe lesiguli. Inhliziyo cardiogram has iphakama lapho izicubu ezithile ezinzima, futhi ukuphakama kwawo namandla awo ubuncane - uma ekhululekile.

I ECG eyenzeke Ukuqoka ngendlela izincwadi, kanjalo kulungiswa ECG kuba kufinyeleleke futhi kulula. Cabangela izindinganiso bathunyelwa kula izincwadi.

P - inquma isimo Atria.

PQ - isikhawu, okubonisa isikhashana lapho unezinkinga, kokubili Atria.

QRS - lezi izifinyezo ukumela isiqeshana electrocardiogram, elibonisa umsebenzi we ventricles inhliziyo.

Q - inquma lizinga umsebenti iyizingxenye engenhla inhliziyo.

R - kubonisa umsebenzi ventricles futhi engxenyeni engaphandle ye-Ezansi inhliziyo.

ST - omunye izinkomba main we electrocardiogram. Lembula umsebenzi kokubili ventricles zenhliziyo. Ochwepheshe ukunaka ngokukhethekile izinga T, elibonisa ukuthi senhliziyo esilimele amaseli ijwayelekile. Kungenxa yalesi ECG uphethwe isici kwenzeka.

I Isikhala phakathi P Q - kuyinto isikhawu yokudlulisela umsebenzi (ngamanye amazwi, amandla, amandla) kusukela ATRIUM ukuba i-ventricle. Ngo ube nenhliziyo enempilo, kumelwe abe imizuzwana 0,12-0,1. Futhi QRS iphakama kumelwe ngiwele isikhawu sesikhathi ngokuhlola imizuzwana 0.06-0.1. Ngokusho lokhu inkomba nayo yakhelwe uphethwe izimo Inhliziyo '.

Ngenhla esixoxe ngazo kuphela izici eziyisisekelo kakhulu ukuthi cardiogram inhliziyo. Sokuqonda ke kuhilela ukusetshenziswa ochwepheshe futhi izinto ezithile ngokuqondile nangokusuka ngokujulile ngezimiso (ngokuhlukile umsipha ngamunye, ama-valve futhi izitsha inhliziyo). Lokhu kukuvumela lokwenza ukuxilongwa esinembile lesi sifo.

Kufanele kukhunjulwe ukuthi okulotshiweyo sokugcina ECG kufanele kwenziwe nguchwepheshe. Nanoma ulwazi imithi, kodwa hhayi njengoba udokotela, ungabona kwi ECG kuphela isithombe olukha phezulu inhliziyo. Beka uphethwe wokugcina futhi zibeka ukwelashwa can kuphela wenhliziyo!
