EKG Cable Science Paub

Kev siv cov txhuas txhuas ntawm ECG txhuas hlau

ECG thiab cov hlau lead tau muab faib ua tsib xim: liab, daj, ntsuab, dub, thiab dawb, thiab dawb yog faib ua C 1. C 2. C 3. C 4. C 5 C6 muaj tag nrho ntawm 10 xov hlau.

QHOV CHAW UA HAUJ LWM RAU TXOJ CAI NTAWM TXOJ CAI, DAJ yog txuas mus rau sab laug Qaum Qaum, Ntsuab yog txuas rau sab laug qis qis, dub yog txuas mus rau sab xis qis qis, thiab txuas mus rau txhua qhov chaw LUB CHEST. LUB TSEV KAWM NTAWV yog raws li nram no:

Limb lead: Limb lead Ⅰ Sab qaum sab xis yog txuas nrog tus ncej tsis zoo, thiab sab laug sab qaum yog txuas nrog tus ncej zoo. Limb lead II txuas nrog tus ncej tsis zoo nyob rau sab xis sab sauv thiab tus ncej zoo nyob rau sab laug sab ceg.

Limb lead III txuas nrog tus ncej tsis zoo nyob rau sab laug sab sauv thiab tus ncej zoo nyob rau sab laug sab ceg. Lub pressurized unipolar limb lead aVR txuas nrog tus ncej zoo nyob rau sab xis sab sauv, thiab tus ncej tsis zoo txuas nrog rau sab laug sab sauv thiab tnws sab laug qis.

Lub pressurized unipolar limb lead aVL, sab laug sab sauv yog txuas nrog tus ncej zoo, thiab sab xis sab sauv thiab sab laug sab ceg yog txuas nrog tus ncej tsis zoo. Lub pressurized unipolar limb lead aVF, sab laug sab qaum yog txuas nrog tus ncej zoo, thiab sab laug sab sauv thiab sab xis sab sauv yog txuas nrog qhov tsis zoo.ncej.

• Lub hauv siab ua: V1 muab tso rau hauv qhov chaw thib 4 ntawm txoj cai sternal ciam teb;

• V2 yog nyob rau hauv 4th intercostal qhov chaw nyob rau sab laug ciam teb ntawm lub sternum, opposite rau V1;

• V3 yog nyob rau nruab nrab ntawm txoj kab txuas ntawm V2 thiab V4;

• V4 nyob rau sab laug Qhov thib tsib intercostal midclavicular kab yog nyob rau hauv lub txiv mis;

• V5 yog sab laug axillary kab ntawm tib theem li V4;

• V6 yog sab laug midaxillary kab ntawm tib theem li V4 thiab V5;

• V7 yog nyob rau sab laug posterior axillary kab, nyob rau tib theem li V4 thiab V5 Kab rov tav dav hlau;

• V8 yog nyob rau sab laug subscapular lub kaum sab xis, tib lub dav hlau kab rov tav li V4, V5, V6, thiab V7;

• V9 nyob rau tib lub dav hlau kab rov tav li V4, V5, thiab V6 ntawm sab laug clavicle;

• V3R, V4R, V5R yog nyob rau sab xis ntawm qhov sib thooj ntawm V3, V4, thiab V5.

• Sab hauv siab, ib qho ntawm sab laug thiab ib qho ntawm sab xis.
