Sinoatrial aeie: mea, lalau mai, lapaau. Haunaele ma ka naau pāpana

Sinoatrial aeie - he pathological ana i ua pu ma ka haunaele o ka maoli naau pāpana. myocardial hapa asynchronously hoemi, no ia mea, he mea he pokole asystole. Maoli ai, e like me ka pohāʻana mea pilikia loa. He nui nā mea maʻi e huli no ka 'ike hou aku e pili ana i kēia maʻi. No ke aha la blockade? Acaeoey oo? Ina he mea kekahi mawaho hoailona? He aha nō nā'āpana hana e kaumaha ana i kēia lapaau? Pane i kēia mau nīnau e ia o ka hoihoi ana i na mea he nui heluhelu.

He aha ka ka sinoatrial aeie?

I mea e wehewehe i ka pathology, mua oe pono e hoʻolohe i ka anatomical a me ka physiological ano o ke kanaka myocardium. E like me oe i ike, o ka naau - ke kino hapa 'ia' hana nona iho. Kona ka ho'ēmiʻana ua hoakaka ia ma ka hana o ka kūikawā ganglion, i hoʻomaka nā aʻalolo impulses.

An nui hapa o na Keaukaha o cardiac pāpana mea sinus wahi. Ua ua ma waena o ka pono atrial appendage, a me ka weheʻana aia o ke kūlana vena cava, i loko o ka akau atrium pa. Sinoatrial i huiia loaʻa paha kekahi mau lala, a me lāʻau Toreli, Bachmann, Wenckebach - ka mea hana impulses i nā paia o nā atria. Hoʻohuikau o ko mākou hopohopo impulse i kēia paena a me ka hea blockage sinoatrial wahi.

Ke'ī mai, e kū'ē i ke kāʻei kua o ka pathology i loko o ka naʻau pāpana i lolelua ka, e alakai i ka asystole, a, o ka papa,'āina pilikia loa. Ua ua olelo mai ia ia mea he pohihihi pathology - ka mea, ua diagnosed ma 0,16% o nā mea maʻi i loko o ka cardiology Oihana. A e like me ke ana helu haʻawina pinepine e ae mai aʻe 'ana o nā kānaka ma luna o kanalima makahiki. Ma ka wahine, e like me haiahū kūmau Ua emi, he pono ole.

Paha i ka hooulu ana o ka blockade, a me ka noho 'ana kamaliʻi, akā, ka mea, IeAUPIIe, IAa IO ia lŘlŘ ma luna o ke kāʻei kua o congenital ke aloha myocardial poino.

I ka papa kuhikuhiE kumu o ka maʻi

Ua Ua maopopo ia CA-blockade mea,ʻaʻole he aupuni kūʻokoʻa maʻi. Ua mea, e aho, he hoailona o nā pathologies. Kokoke 60% o nā mea maʻi me ka blockage hoomanawanui mai coronary naʻau maʻi. Eia hou kekahi, he mea pinepine he pathology ma ke kāʻei kua 'ole ma hope o myocardial infarction.

Eia hou, ma laila nō nā kumu i hiki ke alakai i ka hoʻohuikau 'o ka maʻamau naʻau pāpana. 'Ākena Makaʻu nā mea hoʻomaʻi a me ka mea koʻohune myocarditis, e like me cardio myocardio, calcification o ka naau Muscle congenital palapala cardiomegaly. I kekahi manawa, CA blockade e hoʻomōhala ana i loko o kanaka e loaa ana mai ka rumatika.

Blockade o ka sinoatrial wahi i ke kauoha ma ka hoʻohana 'ana i oi nui nā māhele o cardiac glycosides, Hoʻokolohua-blockers, quinidine a me nā lāʻau. E kūkulu i kekahi pathology pinepine Nā hualoaʻa ma ka oi o ka potasiuma i loko o ke koko. Mai ka hana ana o ka naau ua hooponopono ia e ka vagus nā aʻalolo, i ka mahuahua ana o kona leo hiki no hoi e alakai i arrhythmias (ikaika hawewe paha trauma o ka pahu, e hoʻopaʻa nei i kekahi reflex e ho'āʻo ai i hoomahuahua i ka ha awina o ke aʻalolo a hāʻule pahū wale).

Nā kumu 'ē aʻe nā maʻi puʻuwai a me ka naau kiwikā mā, i ke alo o kaʻeho ma ka lolo, malfunctions thyroid kaheaia hypertension, meningitis, encephalitis, leukemia, cerebral vascular pathology. Me oe e ike, he nui na kamepiula aʻe.

Blockade o ke degere mua, a me kona hiʻona

Ma kēia lapaau ua maheleia i ekolu degere o ka oolea o keia maʻi. Kēlā me kēia no ia i kona mau 'ano. Most mehana a me ka malama sinoatrial aeie mua loa. Me ia pathology kēlā me kēia lāʻau ikiʻai wale i lŘlŘ ma ka sinus wahi, i ka atria ihoiho. Akā, paʻa ka mea, ke hele mai me ka kekahi ke kali ole.

Kēia pathology hiki ole ke ike i ka electrocardiogram, aʻaʻohe mawaho hoikeana - hoʻomanawanui iki mai no ka hapanui loa manao maʻamau. Diagnosing mua ka papahelu hiki blockade i intracardiac EFI.

Blockade o ka lua o ka iho: he manawa pōkole hōʻikeʻano

Kēia ka anu u Ua hiki e puʻunaueʻia ka hooulu ana o ka pathology i loko o nā 'ano:

• Blockade o 2nd degere o ka 'ano mua o ka conductivity ukali ma kekahi gradual emi i loko o ka sinus wahi. Oia ka nahae hiki koke ana ke diagnosed ma ka electrocardiogram. Me ka pili ana i ka mea mawaho symptoms, nā mea maʻi pinepine ohumu o recurring pōniuniu, nawaliwali. E like me ka maʻi pinepine i loko o kanaka ola e alai ae, a me kekahi manawa transient lilo o ka ike paka i hoʻonāukiukiʻia, a mahuahua nui physical haʻawina, ikaika cough,ʻoi 'ana e haʻalele i ke poo, a no laila, ma luna o. D.
• Blockade o ka 2 Makalu degere o ka lua o ka type ua ano pu e kekahi kūlike loa cardiac arrhythmia, a ke haha aku i ka hoʻomanawanui. No ka laʻana, ka mea naʻau ua mua listen (he kanaka i haha aku contractions), a laila, ho opa ao mahana, a me ka hoʻomau 'ana ma hope o ka ihola. I manawa o ka asystole, ka hoʻomanawanui Kahalaopuna he pahikakiwi oi nawaliwali, pinepine nalowale ike paka i.

He aha hoailona pu ma ka blockade o ke kolu o ke degere?

Pathology o ke kolu o ka iho - he piha sinoatrial ai hoi. Ma keia hihia, ke myocardium, a i ole loaa impulses mai ka sinus wahi. Maoli ai, ka pathology ike ma ka electrocardiogram, no ka mea, ke hoʻomanawanui? Acaeoey? Asystole ma ke kāʻei kua o ka piha conduction blockade. Pela ka mea, i ka elusive ectopic pāpana mililani aku i na hana o ke kolu o ka papa o Keaukaha. Iloko o ka ECG hiki ke ike i loaʻa nā ole eiiieaenu PQRST.

ka lapaʻauʻia

Koke ia E e olelo mai la i ke ano o ka lapaau hilinaʻi nui ma luna o ke kumu o ka pathology. Inā sinoatrial aeie ka helehelena a me ka meaʻaʻole i ka hoʻoweliweli 'ana i ke ola o ka hoomanawanui, i ka mea i ho'ākāka' Inc i e pono ai - naau pāpana e hoʻi i ka maʻamau ma iho.

Aka hoi, e pono e hana i ka iniiaiie maʻi. No ka laʻana, ina ka blockade hoʻonāukiuki ma ka mahuahua ma vagal leo, ka mea, he pono i ke ahonui, "Atropine" (ae pani "ephedrine", "Ortsiprepalinom", "isoprenaline"). I ka hanana i kekahi ka hoʻohuikau 'o cardiac pāpana ma luna o ke kāʻei kua o ka overdose, lawe palena papaha pilikia ai' e e pani koke, a ho'āʻo e lawe mai i ke kino o residues o nā lāʻau.

Eia naʻe, he pinepine keia pāpana hana maʻamau hiki aku ai i ke kūpono 'ana o ke fibrosis i loko o ka myocardium. Ma ia manawa, e hoʻopaʻa i ka maʻamau contraction o ka naau Muscle mea hiki wale ma ka ikaika uila stimulation.

First kōkua no ka blockade

E like me ua oleloia, ma ka hapanui o na hihia, blockage He hapa a me ka meaʻaʻole i pololei hoʻoweliweli 'ana i ke ola o ka hoʻomanawanui. Aka hoi, ma kekahi manawa, he piha cessation o ka EYI o ka pou impulses hiki aku ai i ka ulia holo ana o ka naau.

Inā ka naau pāpana ua malama nui setback i ka holo ana, alaila, e paa ana ia atrial i auhele. E like me 'oe ke kau puʻe i ka'ōnohi a (ka mea kōkua, e hoʻololi i ka naʻau like) me ka pōkole-makahiki ana. Eia naʻe, i kekahi manawa i ka hoʻomanawanui koi mālama nui malama, cardiac lomilomi a me ka pilina i ke ola-kākoʻo mīkini.
