Kodi tachycardia ndi chiyani?
Timalankhula za tachycardia pamene, popuma, kupatula kuchita masewera olimbitsa thupi, mtima umagunda mofulumira kwambiri, kuposa 100 mphamvu pa mphindi. Mtima umatengedwa kuti umagunda bwino ngati ukugunda pakati pa 60 ndi 90 pamphindi.
Mu tachycardia, mtima umagunda mofulumira, ndipo nthawi zina mosadziwika bwino. Kuthamanga kwa kugunda kwa mtima uku kungakhale kosatha kapena kosakhalitsa. Nthawi zina sizingayambitse palibe chizindikiro. Nthawi zina, zimatha kuyambitsa chizungulire, kumutu pang'onopang'ono kapena kugunda kwamtima, ngakhale kukomoka. Choncho, tachycardia imatha kuchoka ku vuto lochepa mpaka ku vuto lalikulu kwambiri lomwe lingayambitse kumangidwa kwa mtima.
Kodi kugunda kwa mtima kumasiyana bwanji? Kugunda kwa mtima kumasiyanasiyana malinga ndi momwe thupi limafunira mpweya wabwino. Pamene thupi limafunikira okosijeni wochuluka, mtima umagundanso mofulumira kwambiri, kuti uyendetse maselo ofiira ambiri a mwazi, amene amanyamula mpweya wathu. Motero, pochita masewera olimbitsa thupi, minofu yathu imafuna mpweya wochuluka, mtima umayenda mofulumira. Kuwonjezeka kwa kugunda kwa mtima sikumangosintha kwa mtima wathu, kungathenso kugunda mofulumira, ndiko kunena kuti, mgwirizano mu njira yamphamvu kwambiri. Kuthamanga kwa kugunda kwa mtima kumatsimikiziridwanso ndi momwe mtima umagwirira ntchito. Mu matenda ena a mtima, pangakhale hiccups mu momwe mtima umakhazikitsira kamvekedwe kake. |
Pali mitundu ingapo ya tachycardia:
- Sinus tachycardia : Sichifukwa cha vuto la mtima koma kusintha kwa mtima ku zochitika zinazake. Imatchedwa sinus chifukwa kamvekedwe ka kugunda kwa mtima kumatsimikiziridwa ndi malo enaake mu chiwalo ichi otchedwa sinus node (malo omwe nthawi zambiri amagwetsa mphamvu zamagetsi zomwe zimachititsa kuti mtima udutse). Izi mathamangitsidwe nkusani wa mtima kungakhale zachibadwa, monga momwe zimagwirizanirana ndi kulimbitsa thupi, kusowa kwa okosijeni pamtunda, kupsinjika maganizo, mimba (mtima umayenda mofulumira mwachibadwa pa nthawi ino ya moyo) kapena kutenga zolimbikitsa monga Coffee.
Pankhani yochita masewera olimbitsa thupi, mwachitsanzo, mtima umathamanga kwambiri kuti upereke mpweya wochuluka ku minofu yogwira ntchito. Choncho ndi a anatengera. Pamalo okwera, mpweya umakhala wosowa, mtima umathamanga kuti mpweya wokwanira ubweretsedwe m'thupi ngakhale kuti mpweya wake uli wochepa kwambiri.
Koma kuthamanga kwa mtima kwa sinus uku kungagwirizane ndi vuto linalake zachilendo m’mene mtima umasinthira pofulumizitsa kamvekedwe kake. Izi zimachitika, mwachitsanzo, pakakhala kutentha thupi, kutaya madzi m'thupi, kumwa mankhwala oopsa (mowa, chamba, mankhwala enaake kapena mankhwala), kuchepa kwa magazi m'thupi kapena hyperthyroidism.
Pankhani ya kutaya madzi m'thupi mwachitsanzo, kuchuluka kwa madzi m'mitsuko kumachepetsedwa, mtima umathamanga kuti ulipire. Pankhani ya kuchepa kwa magazi m'thupi, kusowa kwa maselo ofiira a m'magazi kumabweretsa kusowa kwa oxygenation, mtima umathamanga kwambiri kuyesa kupereka mpweya wokwanira ku ziwalo zonse za thupi. Ndi sinus tachycardia, nthawi zambiri munthuyo samazindikira kuti mtima wake ukugunda mofulumira. Izi zitha kukhala tachycardia Kupeza ndi dokotala.
Sinus tachycardia imathanso kukhala yokhudzana ndi wotopa mtima. Ngati mtima ukulephera kugwira bwino ntchito, fupa la sinus limauwuza kuti ugwire pafupipafupi kuti mpweya wokwanira uziyenda m'thupi lonse.
Postural orthostatic tachycardia syndrome (STOP) Anthu omwe ali ndi STOP iyi amavutika kusuntha kuchoka pomwe adagona kupita pamalo oongoka. Panthawi imeneyi, mtima umathamanga kwambiri. Kuwonjezeka kwa mtima kumeneku nthawi zambiri kumatsagana ndi mutu, kumva kudwala, kutopa, nseru, kutuluka thukuta, kupweteka pachifuwa, ndipo nthawi zina ngakhale kukomoka. Vutoli lingakhale lokhudzana ndi matenda, monga shuga, kapena kumwa mankhwala. Amachizidwa ndi madzi abwino ndi mchere wamchere, pulogalamu yophunzitsira miyendo kuti ipititse patsogolo kubwerera kwa magazi a venous kumtima, ndipo mwina mankhwala monga corticosteroids, beta blockers kapena mankhwala ena. |
- Tachycardia yokhudzana ndi vuto la mtima: Mwamwayi, ndizosowa kuposa sinus tachycardia. Chifukwa chakuti mtima uli ndi vuto linalake, umathamanga kwambiri pamene thupi silifuna kugunda mofulumira.
- Tachycardia yolumikizidwa ndi matenda a Bouveret : imakhala pafupipafupi (kuposa munthu m'modzi mwa anthu 450) ndipo nthawi zambiri imakhala yoyipa. Izi ndizovuta mu dongosolo lamagetsi la mtima. Izi anomaly nthawi zina kumayambitsa kuukira tachycardia nkhanza kwa kanthawi asanayime modzidzimutsa. Mtima umatha kugunda kuposa 200 pa mphindi imodzi. Izi zimakwiyitsa ndipo nthawi zambiri zimayambitsa kusapeza bwino kukukakamizani kuti mugone kwakanthawi. Ngakhale pali vuto limeneli, mitima ya anthuwa siidwala ndipo vutoli silichepetsa moyo.
Mtundu wina wa tachycardia ndi Wolf-Parkinson White syndrome, yomwe ilinso yachilendo mu dongosolo lamagetsi la mtima. Izi zimatchedwa paroxysmal supraventricular tachycardia.
Ventricular tachycardia: awa ndi kugunda kofulumira kwa ma ventricles a mtima olumikizidwa ndi matenda amtima (matenda osiyanasiyana). Mitsempha ndi mapampu omwe amagwiritsidwa ntchito kutumiza magazi okhala ndi okosijeni m'thupi lonse (mtsempha wakumanzere) kapena magazi opanda mpweya m'mapapu (ventricle yakumanja). Vuto ndiloti, pamene ma ventricles ayamba kugunda mofulumira kwambiri, mphuno ya ventricular ilibe nthawi yodzaza ndi magazi. The ventricle sakhalanso ndi gawo la Mapampu ogwira. Ndiye pali chiwopsezo choyimitsa kugwira ntchito bwino kwa mtima ndichifukwa chake chiopsezo chakupha.
Chifukwa chake, tachycardia ya ventricular ndizovuta zamtima. Milandu ina ndi yochepa ndipo ina ndi yoopsa kwambiri.
Pazovuta kwambiri, tachycardia ya ventricular imatha kukula utitiri wa fibrication zogwirizana ndi desynchronized contractions of muscle ulusi. M'malo mogwirana zonse mwakamodzi m'mitsempha, ulusi wa minyewayo umalumikizana nthawi iliyonse. Kugunda kwa mtima kumakhala kosagwira ntchito potulutsa magazi, ndipo izi zimakhala ndi zotsatira zofanana ndi kumangidwa kwa mtima. Chifukwa chake mphamvu yokoka. Kugwiritsira ntchito defibrillator kungapulumutse munthuyo.
Atrial kapena tachycardia : ndiko kufulumira kwa kugunda kwa mbali ya mtima: the headsets. Zomalizirazo ndi zibowo ting’onoting’ono, ting’onoting’ono kuposa ma ventricles, amene ntchito yake ndi kutulutsa magazi ku ventricle yakumanzere kupita kumanzere kwa atrium ndi ku ventricle yakumanja kwa atrium yakumanja. Kawirikawiri, mlingo wa tachycardia uwu ndi wokwera (240 mpaka 350), koma ma ventricles amagunda pang'onopang'ono, nthawi zambiri theka la nthawi poyerekeza ndi atria, yomwe idakali yothamanga kwambiri. Munthu sangachite manyazi nthawi zina, kapena angazindikire nthawi zina.
