Tricycardia tricycardia yomwe imaima yokha mkati mwa masekondi 30 amatchedwa tricycardia (non-sustained tachycardia) (NSVT). Popeza tachycardia ya ventricular ingakhale yowopsa mtima , imakhala yoipa kwambiri. Choncho NSVT ndi yoopsa kwambiri kuposa tricycardia ya ventricular yomwe imapitirizabe. Komabe, izi zingayambitse zizindikiro zofunika, ndipo zitha kuwonetsa chiopsezo cha mtima.
Mwachidule
Ndondomeko yeniyeni ya NSVT ndi nthano ya tachycardia ya ventricular yomwe imakhala ndi mtima wokwana 120 kugunda kwa mphindi, yokhala ndi zimbwa zitatu kapena kupitirira mphindi makumi atatu.
Kawirikawiri, NSVT mwina siimachititsa zizindikiro zilizonse, kapena zimangotulutsa zizindikiro. Nthawi zina, NSVT ikhoza kutulutsa kuwala, chizungulire , kapena, kawirikawiri, syncope (kutaya chidziwitso).
Chifukwa NSVT nthawi zambiri sichisonyeza zizindikiro zoopsa, nthawi zambiri zimapezeka panthawiyi, polemba zojambula zamtundu wa electrocardiogram (ECG) kapena panthawi ina yowunika mtima.
Chifukwa chiyani NSVT ndi yofunika?
Pali zifukwa zitatu zomwe NSVT ilili yofunikira. Choyamba, NSVT yokha ingabweretse zizindikiro zovuta. Chachiwiri, icho chingasonyeze kukhalapo kwa matenda oyambirira a mtima osadziwika kale. Pomalizira, kukhalapo kwa NSVT kungasonyeze kuti kusagwirizana kwa magetsi komwe kumakhala koopsa kwambiri, mwinamwake kumatsogolera kuzinthu zoopsa zowonjezera monga ventricular fibrillation .
Kudziwa
Ngati mwapezeka ndi NSVT, ndikofunika kwambiri kuti dokotala wanu ayese kufufuza mtima kuti ayang'ane matenda a mtima.
Mitundu ya matenda a mtima yomwe imagwirizanitsidwa ndi NSVT ndi matenda a mitsempha ya matenda (CAD) ndi mtima wosalimba chifukwa cha kuchepa kwa mtima. NSVT imapezedwanso ndi hypertrophic cardiomyopathy ndi matenda a mtima valve (makamaka aortic stenosis ndi mitral regurgitation ).
Zambiri mwazimenezi zikhoza kuwonetsedwa ndi echocardiogram, koma vuto la thallium likhoza kukhala lothandiza ngati muli ndi zifukwa zoopsa za CAD.
Nthawi zina, NSVT imayambitsa matenda a mtima omwe sagwirizana ndi matenda a mtima (omwe ndi matenda a mtima osasintha mtima wa munthu). Ambiri mwazimenezi ndi kubwereza mobwerezabwereza monomorphic ventricular tachycardia (RMVT) . RMVT ndi matenda osakanikirana omwe amagwiritsa ntchito magetsi a mtima, omwe sapanga kusintha komwe kumawoneka ndi echocardiogram. Matenda ngati awa omwe amabweretsa kachilombo ka HIV kamapezeka kawirikawiri pamene dokotala akuwona zochitika za arrhythmia pa ECG.
Chithandizo
Nthaŵi zambiri, NSVT ndi yofunika makamaka ngati chizindikiro chomwe chimayambitsa matenda a mtima. Ngati matenda a mtima atulukira, mankhwala ayenera kulunjikira. Ngati palibe matenda a mtima amapezeka, ambiri a NSVT sawonjezera chiopsezo cha kumangidwa kwa mtima, ndipo mwachidziwitso chachipatala nthawi zambiri palibe mankhwala omwe akufunikira.
Osati nthawi zambiri, matenda a mtima amodzimodzi amachititsa ngozi yaikulu kwa imfa mwadzidzidzi kuchokera kumaganizo a mtima.
Izi ndi zoona makamaka kwa CAD ndi mtima kulephera. Pazifukwa izi, chiopsezo cha kumangidwa kwa mtima chikugwirizana kwambiri ndi gawo lamanjenje lomwe limachokera ku ventricular kusiyana ndi kupezeka kapena kupezeka kwa NSVT. Pofuna kuchepetsa chiopsezochi, pamene kachigawo kakang'ono ka ejection kakachepetsedweratu, chokhachokhacho chiyenera kuganiziridwa mozama.
Kwa anthu amene ali ndi hypertrophic cardiomyopathy, kukhalapo kwa NSVT kumasonyeza kuti pangakhale ngozi yaikulu ya imfa yadzidzidzi. Choncho anthuwa omwe ali ndi NSVT angapangitse katswiri wamaganizo kudalira njira yowonongeka, makamaka ngati pali mbiri yakufa mwadzidzidzi kuchokera ku hypertrophic cardiomyopathy m'banja.
Kukhala ndi NSVT sikusintha matenda a mtima wa valvular, kuphatikizapo mitral valve prolapse , ndipo pazifukwazi siziyenera kukhala zofunikira pakupanga chisankho.
Achinyamata omwe ali ndi NSVT zambiri ndipo palibe matenda amtima ayenera kutumizidwa kwa katswiri wa mtima wamtima (rhythm rhythm specialist) kuti awonetseredwe kwa RMVT ndi zina zomwe zimayambitsa matendawa. Mitundu ya arrhythmias imatha kuperekedwa ndi mankhwala opatsirana .
Mankhwala
Ngati zinali zophweka komanso / kapena zotetezeka kuchotsa NSVT ndi mankhwala osokoneza bongo, izi sizingakhale funso lovuta. Mwamwayi, mankhwala osokoneza bongo omwe angagwiritsidwe ntchito pochiza NSVT nthawi zambiri sakhala othandiza ndipo amachititsa zotsatira zoopsa kwambiri.
Ngati mankhwalawa akugwiritsidwa ntchito, madokotala ambiri amayamba kugwiritsa ntchito beta blockers , ndiyeno calcium channel blockers , chifukwa mankhwalawa nthawi zina amachepetsa zizindikiro, ndipo amakhala otetezeka. Komabe, ngati mankhwala enieni omwe akugwiritsidwa ntchito akugwiritsidwa ntchito, akuyenera kuti nthawi zonse azitsatiridwa ndi electrophysiologist.
Mfundo yaikulu ndi yakuti kufunika kwa NSVT nthawi zambiri sikuli zokhudza NSVT yokha. M'malo mwake, nthawi zambiri zimakhala zokhudzana ndi kuti NSVT ikhoza kukhala chitsimikizo kwa vuto lalikulu la mtima lomwe liyenera kuyesedwa ndi kuchiritsidwa.
