Beats, wabo

Beats - olu hlobo arrhythmia, ukubonakala ngenxa ukuzenzekela engaqhelekanga kwaye kwakhona Entre mechanism kwaye esizibonakalisa nokubetha kwentliziyo ekuqaleni okanye naliphi na isebe lawo. Ibetha, unobangela kunye nendawo ukuvuselela kwangethuba ezahlukileyo. Kuxhomekeka indawo imbonakalo ahluka: atrial, ventricular ibetha ngaphambi kunye nokuhla esivulekayo okuhlangana atrioventricular.

Beats, izinto ezo emiselwe ixesha ngokwembonakalo, ubiza phambi kwexesha nasemva kwexesha. Ixesha ludlulele kwisethi yangaphambili de ibetha ezintsha, ngokuba kwithuba lokuphumla predektopichesky (ixesha coupling). Yena Iqinisekile ngqo, ebonisa umthombo oqhelekileyo ukuvuselela kwangethuba. ubude ngokungalinganiyo ngamathuba ezinxulumene extrasystoles zeenkalo ezahlukeneyo. Oku itshintsha isimo sabo.

Le unxulumano olusondeleleneyo phakathi Kwemithetho inkangeleko izishunqulelo yokuqala engundoqo isingqi entliziyweni ibangwa ukuvela zenkuthazo ezingaqhelekanga eziphambili (normal) ukubetha - Indlela postdepolyarizatsii, repolarization olungenangqamaniso okanye ukuphinda-Entre.

Iimpawu extrasystoles amanqaku kunye ikhefu elandelayo na ixesha lokuphumla ludlulele phakathi ukwehla kwangethuba kwaye ubume elandelayo kwisingqi esisiseko. Ixesha eliya kuthathwa ikhefu kuxhomekeke ukuba okanye hayi kwakukho wampompoza ukumpompoza esiludumbo sinus. Phezu ekubhobhozeni ethunjini sinus node ukubetha leyo ikhokelele ukusuka excitation ekuqaleni atrial, ukuba angxamele omtsha uqalisa ukwakha kulo ixesha lokuphumla elilingana esisiseko kwisingqi sinus. Ngoko ke ixabiso ekhefu phambi postektopicheskogo ngokuya ngaphezu ezimbini eziqhelekileyo imijikelo kwentliziyo, ke umise ayiphelelanga zembuyekezo. Ukuba wokuqhuba indibano engundoqo arrythmia kwenzeka, kukho ikhefu epheleleyo, oko kukuthi, umdibaniso yaphambi kunye postektopicheskih ngamathuba alinganayo ngexesha lemijikelo ezimbini oluqhelekileyo inhliziyo.

Beats, izinto zabo, amisele oluqukuqelayo kunye nexesha inkangeleko yalo. Ukuncitshiswa ekuqaleni yimiyalezo (umzekelo, ibetha emva kwesidlo) ukuba phantse akukho impembelelo hemodynamics, kodwa ngamanye amaxesha babe ukubaluleka prognostic, ukuba intwasahlobo arrhythmias ngaphezulu kakhulu. beats rhoqo, ngelinye kunye isingqisho esiqhelekileyo, nzima ukuhamba kwegazi lobuchopho. Ukuba ezintathu irekhodi alandelelanayo izishunqulelo ngaphambi kwexesha, le meko evakalayo njenge paroxysm of tachycardia. Kukho inokuba fibrillation wentliziyo, ukuba kukho izishunqulelo yokuqala ngaphambi kwexesha, ukudityaniswa kophulwa iinkqubo pathways kwi myocardium.

nokuncipha Early ibakho intendelezo, ukuvela wabonakalisa P yomtshangatshangiso, nto leyo yahluke ukusuka imilo yesiqhelo kunye nexesha. QRS complex ngokwayo iya kuhlala injalo. Ukunciphisa ventricular-atrial kwakwakhe on cardiogram kuvela etshintshiweyo ventricular ezintsonkothileyo. P izinyo engekhoyo, ekubeni excitation ingqamana atrial ventricular excitation. Ukuba ventricular nokuncipha kwenzeka phambi atrial P igagasi negative kwaye kubonakala emva kokuba isakhiwo ventricular.

nokuncipha yobume ventricles kwi cardiogram kubonwa ekuqaleni esimbaxa ventricular ukuba imilo supraventricular. Phambi extrasystole akukho wave P, izakhiwo ventricular uyandiswa ze zatshintsha. Beats lo ventricle lasekhohlo kuvela kuvalwe iindlela kwibhloko inyanda yesebe vice versa.

zokunciphisa lwakwangoko kunye nasiphi na isifo sentliziyo, kodwa kuvela ngokwabo, ngenxa zezifo nervous libanda, inkqubo iziyobisi, ukungalingani electrolyte, utywala kukuninzi.

Indlela lokuyigxotha le arrhythmia

Kuyimfuneko ukuba ususe zonke izinto ezinegalelo ekunciphiseni ekuqaleni. Nikezela luthoba iziyobisi luvo. cuts Rare musa kufuna unyango olulodwa. Xa kudityaniswe lwegazi extrasystoles umfutho emiselweyo kunye neziyobisi antiarrhythmic (propranolol, verapamil et al.), Amachiza Potassium, ukuba akukho Izimo kuso.
