Beats Ventricular ngaphambi: kwakhona kwenzeka ngokwesiqhelo

Ngendlela eqhelekileyo izinga intliziyo icwangcisa node ekhethekileyo sinoatrial, leyo inokufunyanwa intendelezo ekunene. Ekhulula isimangalo lombane ebangela imithambo ukuncipha. Yena ngenkqubo oluntsonkothileyo iiseli ezizodwa isasazwe ecaleni myocardium. Ukuphinda-phinda izishunqulelo ulawulwa kakuhle luvo eliqhelekileyo humoral ezithile (catecholamines, umz, epinephrine). Ngoko ke intliziyo wayethimb iimfuno host ephilayo yayo, oko kukuthi, ngexesha ngamaxesha embandezelo, imincili okanye izinga frequency amandla omzimba kuba inkulu kakhulu.

Beats - i "ukuverha" Iezothuso ezongezelelweyo kweyesiqhelo kwisingqi wentliziyo, ukuba - intliziyo engaqhelekanga kwaye zidala iingxaki ezongezelelekileyo. Ukuba kwenzeka xa intlawulo sombane ophezulu ukusuka kummandla ngaphandle esiludumbo sinoatrial.

arrhythmias Supraventricular zenzeka kwiimeko ezimbini. Okanye ukuba ezinye indawo intendelezo into depolarized ngaphambi kwexesha, okanye ukuba isantya engaqhelekanga ithumela esiludumbo atrioventricular. Ngowe-60% yabantu abanempilo kukho ibetha ngamnye 'ukuzalwa' ukusuka intendelezo. Noko ke, okufana iimeko ezithile, ezifana nesifo sentliziyo, nabanezinto ezingaqhelekanga ze ivalve mitral. Ukuba ungakwazi ukuqala ucutheko olungalawulwayo - fibrillation, kwaye ke ayikwazi ukuba ngoyaba esktrasistoly. Utywala ne caffeine mandundu le ngxaki.

beats Ventricular ngaphambi kwenzeka abantu na ubudala. Asinto kwaphela ingaqhelekanga. Ukuba ECG emazishicilelwe iiyure ezingama-24, ngoko 63% of cardiolog ezichongiweyo PVCs abangatshatanga abasempilweni ngokupheleleyo. Nangona kunjalo, inani elikhulu kubo zifumaneka kubantu abane kwisakhiwo ngentliziyo engaqhelekanga. Oku kwenzeka kakhulu emva kokuba wahlaselwa yintliziyo.

Abantwana ventricular arrythmia kwenzeka ngayo rhoqo umthambo njengokuba atrial ngokuqhelekileyo ngokwaneleyo rhoqo ngamandla kakhulu ukuba sele wayeka ukuba ivele. Kuphela kwimeko lwesakhiwo engaqhelekanga ye imithambo, oko kunokubangela fibrillation atrial.

Ke yona intliziyo, nto leyo isakhiwo ezichanekileyo, kufuneka ukuba athi, akukho kuyingozi ventricular arrythmia. Noko ke, ukuba baqalise ukuvela rhoqo ngexesha umthambo, loo nto luphawu embi.

Ukuba ukungaqheleki elibhaqiweyo lwesakhiwo, kufuneka utyelele cardiologist. Kungenjalo imeko ibe esisongela ubomi.

Esichengeni obubonakala ibetha ziquka lwegazi, ubudala oqolileyo, hypertrophy ventricular, isifo sentliziyo, cardiomyopathy, ukuswela calcium, nemagnesium nepotassium, amphetamine, lakhula tricyclic, kunye digoxin, kakubi utywala, ntshikilelo, caffeine, kunye nezifo.

Ngokuqhelekileyo, izigulane ezikhala iyangongoza. beats Ventricular ngaphambi walibonakalisa zokunciphisa engaqhelekanga emva ifuthe eqhelekileyo lukhatshwa ingqiqo "ukuyeka" kwentliziyo. It yimvakalelo engaqhelekanga ukuba umntu ezingaqhelekanga, ngoko ziphawuleka njenge uphawu. Abanye abantu ngelo xesha wakhathazeka gqitha.

Ngesiqhelo imeko kuphela sibi, yaye umthwalo - ngokwandisa ngokwayo. Noko ke, ukuba umthwalo ukuba lisomelela, akukho nto uphawu elungileyo.

Kwakhona, iimpawu Abatyhafileyo, ubuthathaka, yaye ukhohlokhohlo esinganyangekiyo ukuba asikwazi bachaza zezinye izinto.

Abo baye ekurhaneleka mgaqweni kwentliziyo izakhiwo echocardiography babelwe ultrasound. Iitsheki yegazi kunye isixa ihomoni, kwakunye ngokwanela electrolyte egazini (calcium, nemagnesium, potassium). Ngokufuthi iisampula zibanjwa kwi a wenyama kwanyanzeleka: extrasystoles rhoqo zitshekishwe phantsi komthwalo yaye baphumle.

Kwiimeko ezininzi ibetha - hayi unesizathu alarm, kodwa ukuba bona ukrokrela kwi - yiya kugqirha omthembileyo. ixhala njalo ke yabulala abantu abangaphezu kwama ibetha.
