ECG ana o ke kumu o nā hoailona

Electrocardiography mea he nui 'ole-invasive iaoia no diagnosing ka iaea ooieoeiiaeuiiai hana o ka naau. Ua Ua nānā 'ana i kakau o ka pou Loaʻaʻia ma ka hoemi infarction, a i hōʻike' ia ma luna o ka pale a me ka pepa.

Ke anamanaʻo hōʻike hypertension, umaumaʻeha a me ka pokole o ka hanu, ma hope o ka makahiki o ka 40, momoku a kiʻekiʻe naʻokoko i loko o ke kino, ma mua kekahi hana, i hāpai keiki, a ma hope maʻiʻaʻai.

E lawe mai i ka electrocardiogram ua hoʻohana 'ia ka kūikawā mea - electrocardiograph me ka mau nā uila aʻa lolo.

ECG maʻamau wehewehe aku ma ka penei hehee wale:

1. nā niho i i hoʻokohu 'ia e nā palapala P, Q, R, a me S, T, U.

It E e hoʻomaopopo i ka niho P e hōʻike mai ana i ka excitation o ka atria. Maʻamau, kona Duration - mai 0.06-0.1 ikaika hawewe - 0.05-2.5 mm o.

A lohe o ECG kōmi manao me ka maopopo i ka huahelu i ka laula o ka mea liʻiliʻi loaʻahā like ma luna o ka pepa, ai ka uilaʻia o ka naau, ua palapalaia, He 0,04 kekona, a me ke kiekie hoʻopili like i ke anakahi uila o 0,1 millivolts.

ECG uku no nā niho:

• Q niho lōʻihi pono e <0,03 me anakahi uila a me ka - <¼ nalu ikaika hawewe mai R;

• R niho e e 0.03-0.04 a (hiki ke hoomahuahua ae la lakou mai V5, a V6 i 26) mai ka 20 mm o;

• S - maʻamau lōʻihi like 'ole o ka nalu hiki 0,03 mau, ke anakahi uila - <8 ma ka kēpau aʻu II, v1 i ia i <25;

• ECG: maʻamau niho T-0,16 kek. A me ka ikaika hawewe - <1/2 o R ka nalu;

• U - kūmau - 0,06-16 me ke kiekie o ka nalu e ia ma kahi o 2-3 mm o.

2.ʻanuʻu: PQ (lāʻau ikiʻai wale hoʻopili like me ka hooholo ma waena o ka atrium a me ka ventricle), QT, a me RR, ST. Hope wā mawaena me ka T nalu characterizes repolarization, i lawe wahi i loko o ka ventricles o ka naau;

3. ka luna 'kekahi loiloi' o QRST, e hoike ana i ka pou systole na ventricles.

No ka mea kakau o ka pou impulses i loko o ka myocardium o ekolu hae ia, e like me ekolu hooolea ana a me kaʻeono ECG umauma hiki aku ai. Ke kūmau o nā hualoaʻa hilinaʻi nui ma luna o ka abduction ma i ka lōʻihi like 'ole a me ka ikaika hawewe o na ale.

It E e hoʻomaopopo i ka ECG mea he loa waiwai PalekanaEND_LINKʻano hana. ECG uku o na kumu a pau hōʻike o ka regularity a me ka pono alapine (frequency) o contractions o ka naʻau, e like me ka mea maʻamau hana o ka Keaukaha o pāpana. Ma lalo o kekahi mau loli hiki ke ike ma ka alo o arrhythmias, cardiac conduction ka haunaele a me ka hiki aʻe 'o myocardial perfusion a me ka ischemia.

ECG kōmi ikaika hawewe mea nui no ka pololeiʻike, mai kona mea ulu mea hiki i ka olelo e pili ana i ka hypertrophy o ka pili pauku o ka naau, a hoʻomōhala i ka hypertension a me kekahi naʻau maʻi.

Au pono aku nei au i ka ECG mea affordable a me ka informative PalekanaEND_LINK iaoia, akā, kona papa kuhikuhiE drawback - ka pōkole lōʻihi like 'ole o ke kakau ana o pou impulses, a i haawi ia e ka naau Muscle. Ia mea,ʻaʻole hiki ke huai ae i ka papa'āweʻaweʻa kemika ka haunaele o ka naau. E huai ae i na abnormalities electrocardiography ka mālamaʻana ua hoʻohana 'ia, a ua paa no ka 48 hola, a' oi aku ka nui piha kiʻi o ka functioning o ka myocardium.

Eia kekahi, no ka mea, i ka palena pauʻike, o ka ke aloha a me ka ooieoeiiaeuiuo kāna hana i loko o ka naʻau i e hana ECG orthostatic haawe a hyperventilation, e like me ka manawa e hooponopono ana i kekahi mau mea haʻilula keimikala (laau Eia kekahi laʻana).
