QRS. Cov Q yoj yog qhov cuam tshuam me me tsis zoo uas ua ntej R yoj . Me me Q yoj (<0.03 vib nas this hauv lub sijhawm) yog qhov pom tau zoo hauv txhua qhov kev coj ua tshwj tsis yog V.1 dhau V3, qhov uas lawv ib txwm muaj kab mob. Qhov R yoj yog thawj qhov kev txav mus los uas tshwm hauv QRS txoj.
Thiaj li, Q yoj ntawm ECG txhais li cas?
Technically, a Q yoj qhia tias qhov kev taw qhia nqa ntawm qhov tso pa tawm thaum ntxov (QRS) cov hluav taws xob ua haujlwm mus rau qhov tsis zoo ntawm cov hlau lead hauv cov lus nug. Txawm hais tias tseem ceeb Q yoj yog tus yam ntxwv pom hauv myocardial infarction, lawv kuj tuaj yeem pom hauv tus lej ntawm qhov tsis raug teeb tsa.
Ib sab saum toj no, muaj dab tsi tshwm sim thaum Q yoj? Txoj cai yog: yog tias yoj tam sim tom qab P. yoj yog kev tawm tsam sab saud, nws yog R yoj ; yog tias nws yog qhov kev poob qis, nws yog a Q yoj : me me Q yoj sib raug zoo rau depolarization ntawm interventricular septum. tus S. yoj qhia txog qhov kawg depolarization ntawm lub ventricles, ntawm lub hauv paus ntawm lub plawv.
Kuj paub, dab tsi yog kab mob Q yoj zoo li?
Q - Yoj ABNORMALITIES Q yoj sawv cev rau theem pib ntawm ventricular depolarization. Lawv yog kab mob yog tias lawv txawv txawv txawv (> 0.2 thib ob) lossis sib txawv tob (> 5 hli). Q yoj uas yog cov kab mob sib sib zog nqus tab sis tsis dav yog feem ntau ntsuas ntawm ventricular hypertrophy.
Vim li cas Q yoj tsis zoo hauv ECG?
Los ntawm kev txhais, a Q yoj rau ntawm electrocardiogram tshuaj xyuas ( ECG ) yog qhov pib tsis zoo deflection ntawm QRS txoj. Technically, a Q yoj qhia tias qhov kev taw qhia nqa ntawm qhov tso pa tawm thaum ntxov (QRS) hluav taws xob ua haujlwm rau lub tsis zoo ncej ntawm cov hlau lead hauv lo lus nug.

Dab tsi yog 5 cov lus nug uas yuav tsum tau nug txog Ap yoj?
P-wave cov lus nug: Puas yog lawv nyob? Lawv puas tshwm sim tas li? Puas muaj ib P-nthwv dej rau txhua QRS txoj haujlwm? Puas yog P-Wave du, sib npaug, thiab ncaj? Puas yog txhua P-Waves muaj cov duab zoo sib xws?
Dab tsi yog siv ntawm ib nrab yoj phaj?
Ib nrab-nthwv dej phaj tau siv los ua qhov hloov pauv polarization, tig lub polarization ncig ib puag ncig nrawm. Quartz yog cov khoom siv feem ntau siv retarder
Dab tsi yog qhov ua tau zoo ntawm ib nrab yoj rectifier?
Qhov ua tau zoo ntawm ib nrab nthwv dej rectifier yog 40.6% thaum RF tsis saib xyuas. Cov ntsiab lus Ripple tau piav qhia txog tus nqi ntawm AC cov ntsiab lus tam sim no hauv cov zis DC. Yog tias ripplefactor tsawg dua, qhov kev ua haujlwm rectifier yuav ntau dua. Theripple tus nqi yog 1.21 rau ib nrab waverectifier
Qhov twg ntawm cov hauv qab no yog hu ua qeeb yoj pw?
Qhov no puas pab tau? Yog · Tsis yog
Dab tsi yog ripple factor ntawm ib nrab yoj rectifier?
Ripple Factor of Half Wave Rectifier 'Ripple' yog qhov tsis xav tau AC tivthaiv ntxiv thaum hloov pauv AC voltage waveform rau hauv DC waveform. Qhov cuam tshuam ripple yog qhov sib piv ntawm RMS tus nqi ntawm AC voltage (ntawm sab nkag) thiab DC voltage (ntawm qhov tso tawm sab) ntawm lub rectifier
