A unipolar coj yog tib tus neeg xyuas pib coj nrog ib tug electrode nyob rau ntawm lub ntsis. A bipolar hmoov muaj ob tug sib cais thiab cais conductors nyob rau hauv ib tug- coj ; qhov hluav taws xob distal nyob ntawm qhov ntxeev ntawm coj thiab lwm tus yog feem ntau txog 2 cm ntau proximal.
Xav txog qhov no, qhov txawv ntawm unipolar thiab bipolar leads yog dab tsi?
Unipolar ua sau npe kev ua si hauv lub plawv uas yog qhia rau, los yog nyob rau hauv qab ntawm lub electrode, whereas bipolar coj sau npe voltage nruab nrab ob electrodes. Cov unipolar coj kuj piv cov qhov sib txawv ntawm lub plawv kev ua ub no thiab qhov voltage los ntawm dab tsi yog hu ua indifferent electrode.
Tsis tas li ntawd, dab tsi yog cov hlau lead bipolar? A coj tsim los ntawm ob electrodes ntawm opposite polarity yog hu ua bipolar lead . A 12 ib- coj ECG muaj peb yam bipolar ko taw ua (I, II, thiab III), lub cev tsis muaj zog ua (AVR, AVL, thiab AVF), thiab rau lub hauv siab unipolar ua , tseem hu ua precordial lossis V ua ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,.
Hauv qhov hais txog qhov no, cov coj tsis sib thooj yog dab tsi?
Unipolar ua (augmented ua ua thiab hauv siab ua ) muaj ib qho kev kaw lus zoo electrode thiab siv qhov sib xyaw ua ke ntawm lwm cov electrodes los ua cov khoom tsis zoo electrode. Feem ntau, thaum ntsuas ECG, tag nrho ua tau sau tseg ib txhij, muab nce mus rau qhov hu ua 12- coj ECG.
Puas muaj bipolar lead coj mus tso rau qhov twg?
Bipolar Leads . Yog, qhov 2 ua nyob rau sab xis thiab sab laug dab teg (los yog lub xub pwg nyom), AVr thiab AVL feem, thiab coj nyob rau sab laug pob taws (los yog sab laug hauv plab) AVf, ua ib daim duab peb sab, hu ua "Einthoven's Triangle". Cov ntaub ntawv sau los ntawm cov no ua hu ua " bipolar ".

Qhov txawv ntawm tus neeg narcissist thiab tus neeg puas siab puas ntsws bipolar yog dab tsi?
Qhia tawm ntawm Pinterest Narcissism yog tus yam ntxwv ntawm kev xav ntawm kev loj hlob thiab tus kheej qhov tseem ceeb. Kev puas siab puas ntsws bipolar yog kev xav tsis meej uas ua rau tus neeg mus ncig ntawm qhov kev xav zoo heev, hu ua mania, thiab qee zaum, kev nyuaj siab. NPD yog ib feem ntawm pab pawg ntawm tus cwj pwm tsis xws luag hu ua pawg B tsis zoo
Vim li cas nws thiaj hu ua 12 lead ECG thaum muaj tsuas yog 10 lead?
12-lead ECG qhia, raws li lub npe cuam tshuam, 12 coj uas tau muab los ntawm txhais tau tias ntawm 10 electrodes. Peb ntawm cov coj no yooj yim to taub, vim lawv tsuas yog qhov tshwm sim ntawm kev sib piv cov peev xwm hluav taws xob kaw los ntawm ob lub electrodes; ib qho hluav taws xob tab tom tshawb nrhiav, thaum lwm qhov yog siv hluav taws xob siv
Dab tsi yog antiarrhythmic yog muab rau pulseless ventricular tachycardia VT thiab ventricular fibrillation VFIB uas tsis teb rau CPR defibrillation thiab vasopressor?
Amiodarone
Dab tsi yog qhov tseem ceeb ntawm qhov sib txawv ntawm unipolar piv rau kev puas siab puas ntsws bipolar?
Unipolar kev nyuaj siab cuam tshuam nrog ntau cov tsos mob kev nyuaj siab (tsis tshua muaj siab), thaum kev nyuaj siab bipolar cuam tshuam nrog ntau qhov kev nyuaj siab thiab tseem muaj cov tsos mob manic (hloov pauv ntawm lub sijhawm tsis tshua muaj siab heev nrog kev zoo siab/chim siab heev)
Vim li cas 12 lead hu ua 12 lead?
12-lead ECG qhia, raws li lub npe qhia, 12 coj uas tau muab los ntawm 10 electrodes. Peb ntawm cov coj no yooj yim to taub, vim lawv tsuas yog qhov tshwm sim ntawm kev sib piv cov peev xwm hluav taws xob kaw los ntawm ob lub electrodes; Ib qho electrode yog tshawb nrhiav, thaum lwm qhov yog siv electrode
