Ka lāʻau ikiʻai: ke ano pana, ka lāʻau ikiʻai papaʻaina ma ka makahiki

Iloko o ka contraction o ka naʻau i loko o ka vascular'ōnaehana ua pahu mai kekahi hapa o ke koko. kona LIKE i loko o ka artery paia hana kuekueni a hoʻopulapula ma ka moku, a hiki i ka periphery i nā mae. Ka mea, i la ia mea me ka lāʻau ikiʻai wale.

He aha mea i ka lāʻau ikiʻai wale?

Ma kānaka, ma laila nō ekolu ano o na moku koko: arteries, aa koko a me capillaries. Release o ke koko mai o ka naʻau i loko o kekahi aoao ai kekahi e loli ai i kela mea keia mea o lakou, ma o na la ia e oscillate pā pōhaku. O ka papa, e like me ka artery hea ka mea me ka ipu naau ke aupuni 'oi paha a hiki i ka aoao o cardiac auaiaea. Fluctuations i loko o ko lākou mau pā pōhaku, ua pono ka manao e palpation, a me ka ipu nui a hiki hiki i ka maka kapa ole. Ia mea ke kumu o ka arterial ka lāʻau ikiʻai o ka loa nui no kaʻike,.

Capillaries - na moku uuku ke koko i loko o ka kanaka kino, akā,ʻo eʻike piʻi ka mea naau. e kuekueni lākou mau paia i ka manawa me ka naau uku, akā, i ka uku hiki e hooponoponoia ia mea, me ke kōkua o kūikawā manaʻo wale. Kekahi 'ai i ka mea kapa ole maka capillary lāʻau ikiʻai wale - he hoailona o ka pathology.

Aa koko mai o ka naau wehe 'ia ai i kā lākou mau pā pōhaku i ole pahee. Ka ai-kapaia venous pāpaʻa - he hoolilo kuekueni me ka pili loa kaulike nui arteries.

No ke aha la e hoʻoholo i ka lāʻau ikiʻai wale?

He aha mea i ka manaʻo nui no kaʻike, o vascular pā pōhaku e kuekueni? No ke aha la i keia no laila, nui?

Lāʻau ikiʻai wale apono 'oe e hoohewa aku i ka haemodynamic, pehea ka pono hoemiia naau Muscle, e pili ana i ka pono nui o ka vascular moe, ma ka pāpana o Kal.

Ma na mea he nui pathological keʻano o ka hanaʻana loli aʻe ka pana, i ka lāʻau ikiʻai wale ano pohaku e kulike i ke kūmau. Kēia i mea e hiki ai i ka manao i ka mea'ōnaehana mānowai koko nenoaiu mea i pau pono.

He aha kiko'î a ho oholo i ka lāʻau ikiʻai wale? Ano o ka lāʻau ikiʻai wale

1. Pāpana. Ka mea maʻamau Pauma ma regularʻanuʻu, a ma keia hope aku i ka naau ana e e rhythmic.
2. Alapine (frequency). Lāʻau ikiʻai wale nalu mea maʻamau like ka nui me ka naau mokomoko ana no minuke.
3. Anakahi uila. Ua uku hilinaʻi nui ma luna o ka systolic ke koko. Ke kiekie ae ia mea, no ka paʻakikī i ka mea mea e oOeEIAOO i ka artery me kou mau manamana lima, 'o ia hoʻi, kiʻekiʻe anakahi uila ka lāʻau ikiʻai.
4. Iie. Ua hilinaʻi nui ma luna o ka buke o ke koko kipakuʻia ka naʻau i systole.
5. Mea. Kēia manaʻo i hoʻopuka pu maʻiʻo a me ka hoʻopilikia.
6. Palapala - o kekahi aiao e hoʻoholo i ka lāʻau ikiʻai wale. lāʻau ikiʻai wale hiʻona i loko o ka haawi hihia hilinaʻi nui ma luna o ke koko, hoʻololi i loko o nā moku i systole (contraction) a me ka diastole (hoʻomaha) o ka naau.

arrhythmias

I ka 'aʻe' ole hanauna o ka lāʻau ikiʻai ma ka naau Muscle contractions o ka naau pāpana loli aʻe, a me ia, a me ka hoʻololi i ka lāʻau ikiʻai wale. Kekahi fluctuations vascular pā hoʻomaka i haule, a hōʻike prematurely, a ma hope kekahi i kekahi i oleʻanuʻu.

He aha nā arrhythmias?

Arrhythmias hoʻololi hana sinus (myocardial hapa i paha ke lāʻau ikiʻai wale kūpono ai i loko o ka ka ho'ēmiʻana o ka naʻau Muscle)

1. Sinus tachycardia - māhuahua alapine (frequency) o contractions.
2. Sinus bradycardia - he emi i loko o ke alapine (frequency) o contractions.
3. Sinus arrhythmia - naau kui i oleʻanuʻu.

Ectopic arrhythmias. Ko lakou helehelena i hiki i ka wa a ka pulakaumaka i loko o ka myocardium me ka ha awina ma luna ma mua o ka sinus wahi. Ma keia kulana, ka hou pacemaker e inhibit i ka ha awina o ka hope, a keʻauhau iā lākou pāpana naʻau kōmi.

1. Mokomoko ana i - ka muli o ka halawai Kal. Ke kaumaha ma muli o ka IIeEeAIEUAA o ka ectopic pulakaumaka o excitation kui iho oe a i atrial, ventricular a me ka atrioventricular.
2. Paroxysmal tachycardia - mahuahua naau i kela ulia (mai i 180-240 Kal no minuke). Like na kui iho oe a hiki e atrial, ventricular a me ka atrioventricular.

'Aʻe' ana i ka lāʻau ikiʻai wale o ka myocardium (blockades). Ke kaumaha ma muli o ka IIeEeAIEUAA o pilikia iaʻi lakou i ka maʻamau holomua o ke aʻalolo impulse mai ka sinoatrial wahi, blockade māheleʻia i loko o nā pūʻulu:

1. Sinoauricular aeie (ka lāʻau ikiʻai hele hou aku ia ma mua o ka sinus'āina).
2. Intraatrial aeie.
3. Atrioventricular aeie (impulse ua i hoololiia mai ka atria a hiki i ka ventricles). I ka piha atrioventricular hihia (III degere) i hiki i ka loaʻa nō nā pacemaker (sinoatrial wahi, a me ka piko o ka excitation i loko o ka naʻau ventricles).
4. Intraventricular aeie.

Kaawale e noho ma luna a me ka blink o atrial kolili a fibrillation. i kēia mau hana hea kapaia loa arrhythmia. Sinus'āina i loko o keia hihia mea hou he pacemaker, a ma ka myocardium o ka atria a ventricles i hana mau ectopic foci o ka excitation e hoakaka i ka naau pāpana me ka alapine (frequency) ka ho'ēmiʻana. Maoli ai, i loko o kēia mau rula, o ka naau Muscle mea,ʻaʻole hiki ke ponoʻole hoemiia. No laila, i ka pathology (oi loa mai na ventricles) mea ola-na olelo hooweliweli au.

Heart kōmi

E oʻioʻi naʻau uku no i kanaka makua, he 60-80 kui iho oe a no minuke. O ka holo ana, keia huahelu loli aʻe ma ke ola. Lāʻau ikiʻai wale ma ka makahiki i kekahi me ka nui loa.

Ua hiki e ka discrepancy ma waena o ka helu ana o Kal a me ka helu o ka lāʻau ikiʻai wale ale. Kēia ia lŘlŘ ina i loko o ke koko kipaku liʻiliʻi koko ka leo (cardiac insufficiency, ka ho'ēmiʻana i loko o ka nui o ka ai hoʻolahaʻia ke koko). Ma keia hihia na oscillations o ka moku paia e ole ana.

Penei, he kanaka ka lāʻau ikiʻai wale (maʻamau no ka makahiki i hōʻike luna) ua ole mau manao iʻike ākea arteries. Kēia,ʻaʻole naʻe, 'aʻole i manaʻo i ua hoemi ole no hoi i ka naau. Aia paha ia i emi ma ka ejection mahele.

anakahi uila

Ke kaumaha ma muli o ka loli ana o keia anakahi ua hoʻololi 'a me ka lāʻau ikiʻai wale. lāʻau ikiʻai wale anakahi uila ano o kona mahele hoʻolako i nā kēiaʻano likeʻole:

1. Paa ka lāʻau ikiʻai. Ma muli o ke kiʻekiʻe ke koko, (BP), o ka oi aku systolic. E'ō'ū i ka artery me kou manamana lima i loko o keia hihia ka loa paʻakikī. Keʻano o kēia lāʻau ikiʻai waleʻano likeʻole Hōʻike i ka pono no ka koke ai? Iaea o ke koko, me ka antihypertensive ai '.
2. Kahi I ka lāʻau ikiʻai. Ke artery Ua'opihia wale, aʻaʻole ka mea, 'o loa maikai, no ka mea, i kēiaʻano o ka lāʻau ikiʻai wale hōʻike o ka oi aku haʻahaʻa ke koko. Ua hiki e no i kekahi mau kumu: i ke ka ho'ēmiʻana o ke koko ka leo, ka ho'ēmiʻana o vascular leo, inefficient Kal.

1. Full. Kēia 'o ia hoʻi i ke koko holo i loko o ka arteries lawa.
2. Nele. Kēia lāʻau ikiʻai wale ia lŘlŘ ka wā he uuku ka leo o ke koko kipakuʻia ka naʻau i systole. Ke kumu no ia o ka moku'āina hiki ke lilo i pathology o ka naau (naau e hemahema, arrhythmia me he nui loa ka naau i kela) a me ka emi ana i loko o ke koko buke i loko o ke kino (koko poho, dehydration).

Ke kumukuai o ka lāʻau ikiʻai wale

Kēia anakahi hiehie i ka maʻiʻo a me ke anakahi uila ka lāʻau ikiʻai. Ua hilinaʻi nui kuhikuhi ma ke anoe o arteries i cardiac contraction a me ka hoʻomaha ma kona palaho infarction. Ka nui o na kēia mauʻano o ka lāʻau ikiʻai wale:

1. Nui (kiʻekiʻe). Ua lŘlŘ i loko o ke kulana home 'ole ma kahi o ka mahuahua ma ka ejection mahele, a ua hoʻemi arterial pā leo. I ka nui o ka puʻe ma ka systole a me ka diastole loli aʻe (no ka kekahi cardiac kalapona o ka hana ka mea, puka mai ia, a laila, emi me ka nui loa). Ke kumu alakai i ka hanana o ka lāʻau ikiʻai wale nui e e aortic insufficiency, thyrotoxicosis, kuni.
2. Small lāʻau ikiʻai wale. Koko i loko o ka vascular kipaku iki leo arterial pā mea kiʻekiʻe, ka'aloʻahiʻa fluctuations ma ka systole a me ka diastole haʻahaʻa. Nā kumu no kēia moku'āina: aortic stenosis, naau e hemahema, hemorrhage, kŰia. Ma pakahi aku la ia hanahana loa hoopii, i ka lāʻau ikiʻai wale cia hiki e ka nīnūnē (keia ua kapaʻia ka lāʻau ikiʻai wale thready).

Ke kinona o ka lāʻau ikiʻai wale oscillation

Ma keia aiao i ka lāʻau ikiʻai wale ua maheleia i loko o ka papa kuhikuhiE waeʻano elua:

1. Fast. Ma keia hihia, i systole ka puʻe i loko o ka aorta ua me ka nui loa, a mahuahua nui, a ma ka diastole emi hikiwawe loa. Rapid pāpaʻa mea he ano hoailona o aortic insufficiency.
2. Lohi. Ke ku pono ana i kulana, ma a he mea he nui puʻe kulu i loko o ka systole a me ka diastole. Oia pāpaʻa ana Hōʻike i ke alo o aortic stenosis.

Pehea e noiʻi ana ka lāʻau ikiʻai pono?

Paha kela kanaka keia kanaka i ike i ka pono e e hana, e hooholo i ka lāʻau ikiʻai wale ana o ke kanaka. Eia naʻe,ʻo ia ka mea manipulation i nā hiʻona i kou pono e ike.

Lāʻau ikiʻai wale hoao no kaʻike ākea (kahahānai) a me ka kumu (carotid) arteries. He nui i ka ike i ka haʻahaʻa cardiac auoiaea ma ka periphery o ka lāʻau ikiʻai wale ale hiki ole ke 'akomi i.

pehea e palpate i ka lāʻau ikiʻai wale ma ka lima noonoo. Kahahānai artery Ua loaʻa no ka noiʻi ma ka pulima oʻu pono ma lalo o ka kumu o ka manamana nui. I ka hoomaopopo ana i ka lāʻau ikiʻai wale palpated nā arteries (haʻalele a me ka pololei), e like me hiki mai i ia wahi, i hiki i ka wa a ka'aloʻahiʻa lāʻau ikiʻai wale E oko a ma nā lima. Kēia paha ia ma muli o ka mīkini'opihia o ka ipu, mai ka waho (e laʻa me,ʻeho) a occlusion o kona lumen (thrombus, atherosclerotic plaque). Ma hope o ke kapakai i ka i ana ai i ka lāʻau ikiʻai ma ka lima ma ka pono palpated. He mea nui i ka hoʻopaʻa 'ana i ka lāʻau ikiʻai fluctuations i loko o ka artery ua ole kekahi manamana lima, a me kekahi mau (loa ka pono hoopuni i ka pulima oʻu no laila, i ka 4 manamana, koe nae ka manamana nui, e noho ana ma luna o ka kahahānai artery).

Pehea o ka lāʻau ikiʻai wale ma ka carotid artery? Ināʻike ākea pāpaʻa ale, uaʻoi aku nawaliwali, e hiki e makaikai i ka lāʻau ikiʻai wale o na moku nui. Ke easiest ala e ho'āʻo a loaʻa ia ma luna o ka carotid artery. E hana i kēia, pono e kau manamana elua ( 'inideka, a waena) ma luna o ke kahi o kaʻana i hoakaka ia artery (ma ka mua kihi o ka sternocleidomastoid Muscle luna i ka Adamu ka'ōnohi). He nui no ka hoomanao ana i ka pono, e noiʻi ana i ka lāʻau ikiʻai wale ma nāʻaoʻaoʻelua mea hiki ole. Ua e ana i ka carotid arteries elua hiki i circulatory haunaele ma o ka lolo.
