Nokuti zvimwe zviratidzo, uye kuona sei kubata ventricular tachycardia?

Rinoreva ventricular tachycardia kuwedzera kwemwoyo pamusoro 100 anorova. / Min. pamwe muzinda panowanikwa ari ventricle. Muna 90% nyaya richiwanika munyika vanhu vane makemikari maronda mwoyo mutinhimira. Kakawanda, mutinhimira kuvhiringidza chokuita coronary tsinga chirwere. Panewo tachycardia kunogona kukonzera myocardial infarction, vachiberekwa uye rheumatic mwoyo chirwere uye nekuve yematambudziko pashure yokurapa pamwe psychotropic zvinodhaka kana mimwe dzokutindivadza.

zviratidzo

Mukana chirwere ichi kunowedzera zera. Men pachena kwaari yakakura kupfuura vakadzi. Vanhu vaduku pane makore 35 tikafunga munhu myocarditis, hypertrophic cardiomyopathy Angatanga ventricular tachycardia. Zviratidzo ndeinotevera:

• pfungwa palpitations, dzungu, kufunganya;
• kupfupika mweya, muchipfuva kurwadziwa;
• Throbbing ari pamutsipa;
• mune zvimwe zviitiko kurwisa simba uye kufenda.

pathophysiology

Ventricular tachycardia kunoitika nenzira mbiri: monomorphic uye polymorphic tachycardia. Monomorphic mhando kunoratidzwa kutevedzana kwezviitiko pulsed excitation rwokuchengeta rusingaperi. Zvinoitika kuti kuratidzwa kwakadai tachycardia kunoitika muna vanhu vane zvayakaita zvakajairika mwoyo. Muzviitiko izvi, kuti kurapwa fungidziro iri kazhinji zvakanaka. Polymorphic ventricular tachycardia chinosiyanisa variability ari kutevedzana kwezviitiko activation of ventricles. The mhaka chirwere ave myocarditis, ischemia kana masero abnormalities ari maumbirwo Ion makwara.

tachycardia kurapwa

Mabatirwo ventricular tachycardia iri dzaidzidziswa kuitwa antiarrhythmic zvinodhaka, izvo runosvika pamusoro pakanyorwa matanho kugadzirisa pane chirwere. Sezvo antiarrhythmic mumiririri inowanzopiwa kuiswa lidocaine. It chinotarisirwa nomutsinga pana 1 MG chete kilogram nokushivirira uremu. Kazhinji, izvi dose kusvika 100 MG uye chinotarisirwa mumaminitsi mashoma. Kana pasina maturo kwemaminitsi 15 kugadzirira inoshandiswa zvakare imwe chete chipimo chemushonga. Kana ventricular tachycardia achabatsirwa nezvinodzvinyirira donhwe, kuwedzera nokushandisa pressor amines. Izvi achadzorera sinus mutinhimira. Kudhaka cardiac glycosides ventricular tachycardia kubatwa potassium chloride uye lidocaine kana zvinodhaka "obzidan" rinoshandiswa.

The kuenderera kurapwa mushure kupora kwemwoyo

Kana mutinhimira rakadzorerwa Zvinofungidzirwa fungidziro uye anoshivirira utariri ronga kuti akambochera. Iye anodomwa neMutungamiriri zvinodhaka jekiseni kana kugadzwa cardioverter-defibrillator kana anobudisa mushonga zvishoma nezvishoma ablation. Kunewo aibatanidza marapirwo. Dzinowanzotanga kushandiswa kana pane chakakomba STRUCTURAL abnormality mwoyo. Anobudisa mushonga zvishoma nezvishoma ablation Somuenzaniso, unogona kuwedzera kushanda zvakanaka pamusoro antiarrhythmic kurapa, kana kuchaderedza zvinoyerera mwero akasima cardioverter-defibrillator.
