Disturbance ntawm intraventricular conduction ntawm lub plawv.

Lub pathology ntawm cov hlab plawv system yog tam sim no mus rau hauv thawj qhov chaw rau tag nrho cov lwm yam feem ntau.

Ob peb cov neeg nyob rau hauv lub niaj hnub ntiaj teb no tsis tau hnov ntawm atherosclerosis mob ntawm cov hlab plawv system. Cov pathological tej yam kev mob li cas, thiab disturbance ntawm intraventricular conduction ntawm lub plawv.

Kev ua txhaum ntawm hais tias conductivity yog tsis tas cov tsis tuaj kawm ntawv ntawm lub tso cai ntawm paj impulses. Qhov no raws li txoj cai qhia ib tug ua txhaum nyob rau hauv povodyaschey system uas yuav manifest nws tus kheej raws li ib tug deceleration zaus kis tau tus mob pulses (thiab deceleration tus nqi, ntsig txog) thiab ua kom tiav tas ntawm cov zaj uas lub pulses (cardiac ntes). Yog li, disturbance ntawm intraventricular conduction ntawm lub plawv manifested lub plawv thaiv. Raws li, lawv muab faib ua tiav (tsis muaj tau ntawm zaj ntawm ib tug paj impulse) thiab tsis tag uas paj impulses yog ua nrog tsawg zaus.

Ntxiv mus, disturbance ntawm intraventricular mob conduction yuav categorized los ntawm qhov chaw txhab (e.g., blockade ntawm txoj cai los yog sab laug nras-ceg thaiv). Cia li tag nrho cov blockade yuav tau muab faib mus rau hauv proximal thiab distal. Thaum nws los txog rau lub distal feem ntawm lub paj fibers ntawm lub mob cov ntaub so ntswg, lawv yog tsawg paaj thiab demand ntau dua mloog los ntawm tus kws kho mob.

Lwm embodiment blockades kev faib: pheej (mob los yog pheej) thiab nraum (mob los yog tsis ruaj tsis khov).

Yog vim li cas uas yuav ua rau disturbance ntawm intraventricular conduction ntawm lub plawv yuav tsum tau muab faib mus rau hauv peb lub ntsiab pawg: organic, kev haumxeeb thiab lam.

Organic - hloov cov qauv ntawm cov mob conduction system. Tej kev hloov yuav tshwm sim nyob rau hauv myocarditis, coronary mob plawv (lub plawv nres, angina, infarction, thiab lwm tus), congenital tsis xws luag, cardiomyopathies, thiab tej zaum tom qab kev phais.

Kev hloov - hloov nyob rau hauv lub mob conduction system nyob rau hauv lub qhaj ntawv ntawm cov organic pathology CCC. Lub ntsiab tshuab regulating tus ua hauj lwm ntawm lub mob conduction system yog cov sympathetic thiab parasympathetic systems. Nyob rau hauv cov ntaub ntawv no, lub sympathetic system tsub kom lub conductivity thiab parasympathetic - slows. Nyob rau hauv lag luam ntawm cov tshuab ob yog balanced, txawm li cas los, nrog cov tsis txaus cai haumxeeb hloov nyob rau hauv cov hlab plawv system. Nce kev ua si ntawm lub parasympathetic system - "vagotonia".

Drug vim ua. Qhov no pab pawg neeg no muaj xws li tshuaj, uas nws muaj nuj nqi tej zaum yuav ua rau sib txawv ntawm lub plawv atherosclerosis. Ib tug feature ntawm no pab pawg neeg blockades yog tsis tshua muaj hnyav thaum lub sij hawm thiab torpid (heev) kev kho mob.

Kev ua txhaum intraventricular conduction thiaj paub tias yog los ntawm electrocardiographic txoj kev. Nyob rau hauv lub xub ntiag ntawm nraum arrhythmias ua ib tug tshwj xeeb version ntawm ECG kev tshawb fawb - Holter xyuas.

Raws li tus txheej txheem ECG nws yog ib qhov nyuaj los txiav txim rau qhov chaw, li ntawd, nyob rau hauv thiaj li yuav meej lub xub ntiag ntawm proximal los yog distal blockade nqa tawm lub npe Nws nras electrogram (EPG).

Yuav kom ntes kev koom tes ntawm poob siab system (ntawm lub sympathetic thiab parasimpatiki) nyob rau hauv yuav ua blockade nqa ce kam kuaj.

Yog li, qhov mob ntawm lub plawv kab mob no yog tam sim no tsim kom meej meej heev thiab meej, uas koj tau yooj yim qhia cov ntxaug ntawm intraventricular conduction ntawm lub plawv. Kev kho mob ntawm no pab pawg neeg ntawm cov kab mob feem ntau vim etiological nam. Uas yog, cov kev kho mob nyob rau hauv thawj qhov chaw yuav tsum tau tswj xa cov ua ntawm lub blockade thiab tsuas secondarily - symptomatic kev kho mob.
