Deciphering ECG naau

Deciphering ECG hiki reliably huai ae abnormalities ma cardiac papa,ʻimi ana i ka hālawa me ke kiʻi o ka naau kōmi. Electrocardiogram - i ka hoʻopaʻa 'ana o ka ha awina o cardiac ha awina no i kekahi wā o ka manawa. Ua Hōʻike 'ia ka pou keʻano o ka hanaʻana i loko o ka naʻau Muscle, e like me depolarization - pīhoihoi, a me ka repolarization - ka hoihoi hou ia ana o myocardial keena. Electrocardiogram hana transthoracic, i mea, ma o ka pahu, ka hoʻohana 'ana nā uila aʻa lolo kau ma luna o ka ili luna, me ka hou i hoʻopaʻa' ia o nāʻikepili ma ke kupaianaha hoʻoluku. Kupono omńkalakala o ECG hoʻolako ka manawa e pono hookupaa nui ae i ka pololei a me kaʻike,, ina he pono, e hooholo i ka 'eleu lapaau.

ECG ninoieo o nā kiʻi o ka niho Hoʻohana a me kau. Dents cardiogram - o ka lōʻihi wahi o ka hālawa laina i ko Roma palapala characterizing ke kēia nāʻikepili: atrial contraction (P), ventricular contractions (Q, R, S) a me ka ventricular hoʻomaha (T). Laumeki, «U» mea fickle a me ke kuka kakauia. Hoʻohana - Hoʻohana mea he pololei laina i ka pili niho. Ka nui o ka transcript o ka electrocardiogram ma ka PQ, a ST Hoʻohana. No ka laʻana, PQ contour laina i hanaʻia i loko o ka excitation au o kali hou aku; i loko o ka atrioventricular (atrioventricular) wahi. ʻanuʻu - he huihui 'ana o nā niho a me Hoʻohana. Ka mea nui wale ECGʻanuʻu nāʻanuʻu PQ, a Q- T.

Excitation i loko o ka myocardium o ka naau ventricles ua wehewehe aku ma keʻano ma ka ECG QRS luna 'kau, no ka mea, mea wale nō i ka papakaukau atrium Muscle ole, akā, i ka mea o ka interventricular septum. Nā QRS eiiieaena manaʻo mua i ka nui o na kanaka niho. Inā nalu ikaika hawewe aku i 5 mm o, keia ua koho paukü palapala Q, R, a me S, ma ka ikaika hawewe o ke noi mea uuku i ka nui, ka mea, ua hoakaka uuku palapala Q, R a mau. Deciphering ECG komo ai i ka pololei heluhelu ana o na niho. Laumeki, R (R) -, kēlā ua kuhikuhi iluna - maikaʻi niho e pili ana i ka luna 'QRS. Kekahi lalo - io niho e waiho ana ma ka niho mua ona R, ua hoakaka me Q (Q), a me lalo iho o ka niho R - o ka niho S (s). Laumeki, Q characterizes ka depolarization o ka interventricular septum, myocardial infarction, a me ka mea, mai ka, ua kīkoʻo akula ka hohonu waiwai. Laumeki, R Hōʻike depolarization o ka bulk o ka myocardium, a me S hōʻike i ka niho pauku o atrial ha awina o ka interventricular septum.

Deciphering ECG naau ninoieo o ka elima-welau heluhelu noiʻi:

1. Ka Ikepili o ka naau i kela a me cardiac conduction. Kēia Ka Ikepili kuhi periodicity olelo naʻau ana, manao paa o ka naau i kela (HR), i ka hoʻokumu o ka excitation kumu, a me ka conduction ano;

2. Ka hoʻoholo o ka pou (axis) o ka naau lāʻau ikiʻai wale;

3. Study atrial nalu P;

4. ka like o ka luna 'QRST;

5. Panina Manaʻo ECG lapaʻau 'ana.

Deciphering ECG naau ola kanaka hoʻomaka me ka pōkole atrial nalu (ab), hōʻikeʻana i ka loli ma ka 'auhau o ka ventricles me ke koko komo i ka manawa o ka systole - atrial contraction. Ma keia electrocardiogram nalu mea ma kēlāʻaoʻao o ka P-nalu, a laila, hele mai, e hoike ana i ventricular systole. Kēia pali ala (b-d) penei ka niho Q, a kolo ana i ka papamoe wahi (D-e). Ka hoʻomaha au o ka ventricle hema, a me ka manaʻo koikoi ka ho'ēmiʻana i loko ona, i ka hālawa ikaika hina ia (e-g), g. Wahi hoʻopili like me ka puka o ka mitral kiwikā , a me ka naku ana o ke koko i loko o ka ventricles. Ma ka hou o ka ka ho'ēmiʻana mea he wahi e hoʻopili like i ke anakahi uila o ka mitral kiwikā, a me ka wahi o ka. F, e like me ka panina o ka aortic kiwikā. Ma hope o ka systolic nalu pepa ventricular iie nalu (g-h) a me ka 'ūlōlohi lākou maʻiʻo (k-he). Ukali ma ka hou ECG kalapona o ke ola i ke kanaka naʻau.
