Beats, izimbangela zazo

Beats - lokhu uhlobo arrhythmia, kokuvela ngenxa automaticity okungafanele kabusha Entre indlela futhi kubonakala ukushaya kwenhliziyo ekuseni noma yimiphi iminyango yalo. Beats, imbangela nendawo ukushukuma ekuseni zihlukile. Kuye esikhundleni ukubukeka ababonakali ngezikhundla: atrial, ventricular amabhithi nisebancane nokuncipha okwenzeka kwalapho atrioventricular.

Beats, izimbangela zazo kunqunywa ngesikhathi ukubonakala, ubiza ekuseni khulu, ngemuva kwesikhathi. Isikhathi sihamba kusukela isethi odlule kuze amabhithi, okuthiwa isikhawu predektopichesky (elihlangana isikhathi). Yena akuvunyelwe fixed, okubonisa ziwumthombo ovamile ukushukuma ekuseni. Ubude engalingani ngezikhathi elihlobene ne extrasystoles ezindaweni ezahlukene. Lokhu kushintsha isimo sabo.

I buhlobene eduze ukubukeka Kufinyeta yokuqala esemqoka isigqi inhliziyo kubangelwa ukuvela yamaholo okungavamile main (evamile) ishayela - indlela postdepolyarizatsii, repolarization indlela noma kabusha Entre.

Izakhiwo extrasystoles amanothi ikhefu okwalandela kuyinto isikhawu ezingamabhande yedlula ukwehla ekuqaleni futhi ishayela alandelayo isigqi eziyisisekelo. Isikhathi ikhefu incike yini noma cha kwakukhona ukudedelwa engeyokuqala itheku. Lapho osenyameni ethunjini itheku node ishayela okwaholela kusukela ekuqaleni excitation atrial, yisifiso entsha uqala ukwakha kuwo isikhawu sesikhathi ngokuhlola ilingane eziyisisekelo itheku isigqi. Khona-ke ukubaluleka pre- kanye postektopicheskogo ngezikhawu uthole emifushane than evamile imijikelezo inhliziyo, akuphelele misa isikhashana compensatory. Uma wokuqhuba umhlangano eyinhloko arrythmia kwenzeka, kukhona ikhefu ephelele, okungukuthi, isamba pre- kanye postektopicheskih ngezikhawu ilingane nobude imijikelezo ezimbili ezivamile inhliziyo.

Beats, izimbangela zazo, ukucacisa imvamisa nesikhathi kakhulu ngokubukeka kwabo. Angavamile ukunciphisa ekuseni (isibonelo, ishaya emva kokudla) kwadingeka cishe namthelela hemodynamics, kodwa ngezinye izikhathi zingase zisho okuthile okubalulekile prognostic, ngokuba kuzalwa arrhythmias eyingozi. amabhithi njalo, nese isigqi evamile, nzima cerebral ukugeleza kwegazi. Uma ezintathu irekhodi elandelanayo Kufinyeta ngaphambi kwesikhathi, lesi simo is esichazwa njengesono esiphambene paroxysm ka tachycardia. Kungase kube fibrillation wenhliziyo, uma kukhona ekuseni Kufinyeta ngaphambi kwesikhathi, kuhlangene kuphula umthetho we izinqubo umzimba e myocardium.

ukusikwa Early okwenzeka ATRIUM, ukubukeka wabonakaliswa P igagasi, okuyinto ihlukile ukuma evamile kanye nesikhathi. QRS eziyinkimbinkimbi uqobo uhlala okufanayo. Ukuncishiswa kwakwakhe ventricular-atrial ku cardiogram avele ezishintshwe ventricular eziyinkimbinkimbi. P izinyo ulahlekile, kusukela excitation kuvumelana atrial ventricular excitation. Uma ventricular ukusikwa kwenzeka ngaphambi atrial P wave alivumi futhi ibonakala emva eziyinkimbinkimbi ventricular.

ukusikwa Sakudala ventricles ku cardiogram wazibona njengoba ekuqaleni ventricular eziyinkimbinkimbi kokuba ukuma supraventricular. Ngaphambi extrasystole kungekho P igagasi, ventricular izakhiwo enwetshiwe washintsha. Beats i-ventricle engakwesobunxele avele nokuvinjelwa kwesokudla block besigaxa legatsha, noHezekeli.

Beats, izimbangela zazo

entengo Early ungakwazi ukuhamba yisiphi isifo senhliziyo, kodwa kungase kuvele bebodwa, ngenxa yezifo kwemizwa uhlelo izidakamizwa ukweqisa izidakamizwa, electrolyte ukungalingani, utshwala obuningi.

Indlela ukuqeda le arrhythmia

Kuyadingeka ukuba aqede zonke izici ukuthi nomthelela ekuncishisweni ekuseni. Yetha uthulisa kwemizwa uhlelo izidakamizwa. ukusikeka ezingavamile angadingi ukuphathwa ngendlela ekhethekile. Lapho kuhlangene nomfutho wegazi ophezulu extrasystoles antihypertensive anqunyiwe izidakamizwa antiarrhythmic (propranolol, verapamil et al.), Potassium amaphilisi, uma kungekho contraindications nalokho.
