Video: Dab tsi yog qhov tseem ceeb tshaj plaws ECG hloov pauv cuam tshuam nrog hyperkalemia?
2024 Tus sau: Michael Samuels | [email protected]. Kawg hloov kho: 2023-12-16 01:44
ECG hloov muaj qhov kev txhim kho txuas ntxiv, uas muaj qhov cuam tshuam nrog nrog poov tshuaj qib. Thaum Ntxov kev hloov ntawm hyperkalemia suav nrog qhov siab, peaked T nthwv dej nrog lub hauv paus nqaim, pom zoo tshaj plaws hauv kev coj ua ntej; luv QT luv; thiab ST-ntu kev nyuaj siab.
Ib qho ntxiv, ECG kuaj pom hyperkalemia li cas?
Classic qhia ntawm chronological ECG hloov pauv ntawm hyperkalemia suav nrog:
- Peaked T tsis.
- Kev ncua sij hawm ntawm PR.
- Kev nthuav dav QRS Txoj.
- P poob ntawm P yoj.
- “Sine Wave” Cov
- Asystole.
Ib tus kuj tseem yuav nug tau, cov tshuaj potassium cuam tshuam rau ECG li cas? Zoo ib yam li elevated poov tshuaj qib, qis poov tshuaj qib ua tau ua rau myocardial arrhythmias thiab tseem ceeb ectopy. EKG kev hloov ua tau suav nrog nce qhov dav thiab dav ntawm P yoj, T nthwv dej flattening thiab inversion, muaj zog U nthwv dej thiab pom ntev QT sib nrug vim kev sib koom ntawm T thiab U nthwv dej.
Tsis tas li ntawd, dab tsi arrhythmia tshwm sim los ntawm hyperkalemia?
Arrhythmia Mechanisms hnyav hyperkalemia ([Koj+]o > 7.0 mmol/L) tuaj yeem ua rau lub plawv nres, asystole, thiab VT / VF. Hauv tib neeg, qib tseeb ntawm hyperkalemia tsim tawm (los yog tsis tsim) cov kev hloov no sib txawv heev.
Vim li cas cov poov tshuaj siab ua rau peaked T wave?
Hyperkalemia: Hyperkalemia yog ib qho tshwm sim ua ntawm siab los yog peaked T tsis . Hyperkalemia cuam tshuam rau qhov gradient, nce kev ua ntawm myocardial poov tshuaj channel, cuam tshuam rau kev rov ua dua tshiab thiab kev tshem tawm. Ntawm thawj ECG qhov tshwm sim ntawm hyperkalemia yog qhov cuam tshuam rau T vuag.

Cov kev hloov pauv hauv metabolic cuam tshuam nrog cev xeeb tub yog dab tsi?
Kev cev xeeb tub ua rau muaj kev hloov pauv hauv lub cev ntawm niam thiab kev hloov pauv lub neej, suav nrog 34 poob qis ntawm cov tshuaj insulin, ua kom cov rog hauv lub cev, rog rog hauv lub cev rov faib dua, 35 txo kev tawm dag zog lub cev, thiab nce calorie ntau ntxiv [5] [6] [7], uas cuam tshuam nrog siab dua 36 txoj kev pheej hmoo ntawm GDM 8,9
Cov leeg twg yog qhov tseem ceeb tshaj plaws rau kev sib hloov ntawm lub xub pwg sib koom?
Cov leeg no suav nrog latissimus dorsi thiab posterior fibers ntawm lub deltoids, nrog ob qho ua yeeb yam tseem ceeb tshaj. Teres loj tseem pab ua qhov haujlwm no. Pectoralis loj thiab latissimus dorsi ua tus yeeb ncuab. Thaj tsam nruab nrab ntawm cov leeg nqaij deltoid yog qhov tseem ceeb tshaj plaws rau kev rub caj npab
Dab tsi ob leeg yog qhov tseem ceeb tshaj plaws hauv kev hloov pauv ntawm ko taw?
Gastrocnemius yog ib qho ntawm cov leeg nqaij uas ua haujlwm zoo tshaj plaws hauv kev cog qoob loo. Qhov no yog qhov dav thiab muaj zog cov leeg uas tseem pib qab lub hauv caug thiab khiav hauv qab theastastnemius. Nws koom ua ke rau hauv gastrocnemius txhawm rau tsim cov leeg Achilles ntawm pob taws
Dab tsi yog qhov tseem ceeb tshaj plaws thaum saib xyuas tus neeg mob uas muaj kev qaug zog tonic clonic qaug dab peg?
Khaws tus neeg SAFE. Pab tus neeg pw, thiab tso qee yam muag muag hauv qab taub hau thiab caj dab. Khaws tus neeg (tshwj xeeb tshaj yog lub taub hau) kom deb ntawm cov khoom ntse lossis tawv, xws li kaum ntawm lub rooj. Xoob tag nrho cov khaub ncaws nruj
Lub koom haum ntawm cov leeg pob txha los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj plaws yog dab tsi?
Skeletal thiab cardiac nqaij fibers. Npaj cov leeg hauv qab no los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj plaws: nqaij fiber ntau, fascicle, myofibril, filament, nqaij. Npaj cov nqaij mos sib txuas hauv qab no los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj: epimysium, perimysium, fascia, endomysium. cov sarcomere
