ECG ọnụego nke ihe ndị bụ isi na-egosi

Electrocardiography bụ ihe dị mkpa ndị na-abụghị invasive usoro Ịchọpụta Otú Nsogbu ọtọ ọrụ nke obi. Ọ dabeere na ndebanye aha nke eletriki potentials na mbenata infarction, nke na-egosipụta na ihuenyo ma ọ bụ akwụkwọ.

Ndị nnyocha e mere na-egosi na ọbara mgbali elu, obi mgbu na iku ume ọkụ ọkụ, mgbe ọ dị afọ 40, na-aṅụ sịga na elu cholesterol ke idem, tupu ọ bụla ọrụ, n'oge ime na mgbe ọrịa.

Iji mepụta ihe ngwá na-eji a pụrụ iche ngwaọrụ - electrocardiograph na nwoke electrodes.

ECG ejikari ji ndị na-esonụ ihe:

1. The ezé nke na-kpọrọ akwụkwọ ozi P, Q, R, na S, T, US Geological

Ọ ga-kwuru na eze P na-egosi otú ndị excitation nke atria. Nọmalị, ya oge - site 0.06-0.1 njupụta - 0.05-2.5 mm.

Mgbe ECG ọnụego kpebisiri ike na-adịrị ọgụgụ na obosara nke dịkarịa ala square na akwụkwọ, agaghi asu electric potentials nke obi na-dere, bụ 0,04 sekọnd, na idi-elu kwekọrọ na voltaji nke 0,1 millivolts.

ECG ọnụego ọzọ ezé:

• Q nha nha ogologo ga-<0.03 na voltaji na - <¼ efegharị efegharị njupụta si R;

• R nha nha kwesịrị 0.03-0.04 na ruo 20 mm (V5 na V6 nwere ike mụbara ruo 26);

• S - nkịtị oge nke-efegharị efegharị esịmde 0.03 s, na voltaji - <8 na-edu ndú m II, bọmbụ V1 nwere ike a <25;

• ECG: nkịtị nha nha T-0,16 sec na njupụta - <1/2 na-efegharị efegharị R;

• U - norm - 0,06-16 na elu nke na-efegharị efegharị kwesịrị banyere 2-3 mm.

2. etiti: PQ (usu kwekọrọ na Itie n'etiti atrium na ventricle), QT, na RR, ST. Ikpeazụ nkeji na T ife ihe e ji mara repolarization, nke na-ewe ebe na ventricles nke obi;

3. The mgbagwoju na-inyocha QRST, na-egosi eletriki systole na ventricles.

Maka aha nke eletriki gboo na myocardium nke atọ ọkọlọtọ mee, nakwa dị ka atọ stiffened na isii ECG obi na-eduga. The norm nke na-arụpụta na-adabere na-mgbatị nke oge na njupụta nke ebili mmiri.

Ọ ga-kwuru na ECG bụ nnọọ ihe bara uru na-achọpụta ọrịa Usoro. ECG ọnụego nke niile ọcha indicative nke mgbe nile na ihe kwesịrị ekwesị ugboro ole nke contractions nke obi, nakwa dị ka nkịtị ọrụ nke onye na-akwọ nke n'afọ iri na ụma. N'okpuru mgbanwe ụfọdụ nwere ike hụrụ na ọnụnọ nke arrhythmias, gbasara obi conduction disturbances ma ọ bụ nke o kwere omume imebi nke myocardial perfusion na ischemia.

ECG ọnụego njupụta dị mkpa ka ihe na-arịa, ebe ya na-abawanye bụ omume na-ekwu okwu banyere hypertrophy nke mkpa ngalaba nke obi, nke na-amalite ọbara mgbali na ụfọdụ obi ọrịa.

M ga-asị na ECG bụ ọnụ na ihe ọmụma na-achọpụta ọrịa usoro, ma ya isi drawback - obere oge nke aha nke eletriki gboo, nke na-na-ekesa site na obi muscle. Ọ gaghị ekwe omume ịchọpụta oge nsogbu nke obi. Iji chọpụta otú ahụ abnormalities electrocardiography nlekota na-eji, nke a na-ẹkenịmde maka 48 awa ma na-enye a zuru ezu karị, na foto nke ịrụ ọrụ nke myocardium.

Ọzọkwa, maka na esi nchoputa nke organic na ọtọ ọrịa na obi nwere ike rụrụ ECG orthostatic ibu ma ọ bụ hyperventilation, nakwa dị ka n'oge ochichi nke iche iche formulations (ọgwụ samples).
