Heart isingqisho kwiimeko eziqhelekileyo kunye zophendlo lwezifo

Isingqisho Intliziyo uxhomekeke ngqo kwi pulses efunyenwe esiludumbo sinoatrial ukuba umqhubi ephambili izinga lentliziyo, okanye ezinye iindawo zale nkqubo Uhanjiso. Xa sinus node eqhelekileyo yenza la nge frequency 60-100 elingu-1, oko abathintela abaqhubi ngenye kunokwenzeka kwesingqisho intliziyo. Inkangeleko ukucuthwa ngamnye bayihambahamba kumathuba efanayo. Ukutshintsha ubude bexesha phakathi umntu amanxeba kukhokelela kokunciphisa systole - ukubetha okanye ukuncipha ukuzala - ukucuthwa intliziyo. Oku kulawulwa kwinkqubo yonyango, isingqisho intliziyo ngoncedo iihomoni kunye nenkqubo yawo luvo.

ukubetha kwentliziyo kakubi esibonakaliswa ngohlobo kukukhawuleziswa, deceleration, kunye ukubonakala imivumbo ezongezelelweyo Ukungafani epheleleyo a kwamathumbu ingalawuleki.

Kutheni Yodilizwa izinga intliziyo?

Ingcambu ezibangela oku kunokuba isifo sentliziyo ezahlukahlukeneyo, nto leyo ekuhambeni kwexesha kukhokelela kuphuhliso iimpawu abagulayo -simptomokompleksu sinus syndrome ukuba shwaka, kubonakala ukuba utshintshe. Ezi ziquka ukuvela nesiyezi, ukudinwa, niphele, ukuphazamiseka osezingqondweni, ukusilela intliziyo. Ngomhla kwisingqi kwentliziyo zinefuthe kakhulu ezi zizathu zilandelayo:

- air-ukungabikho (hypoxia);

- BP;

- iposi engabalulekanga kunye nezinye iintlobo kwemithambo;

- isifo sentliziyo kunye nesifo yokukrala myocardium;

- azalwa utshintsha sinus;

- ukusetyenziswa kwezinto excitatory;

- izifo ezidalwe;

- ukusetyenziswa arhente ezithile zonyango;

- kukuzingxala ngokutya, ukusebenzisa kakubi utywala, ukutshaya;

- stress nokungafunwa oba;

- igazi;

- ukusilela intliziyo;

- sindisa ngokomzimba.

Yintoni ukuphazamiseka rhythm intliziyo

Heart ukuphazamiseka isingqisho kwenzeka phantse onke amadoda ebomini babo. Kudla arrhythmias imithetho ombane, kwezinye iimeko - ngezifo. Arrhythmias zidla Iimpawu zokuqala nesifo sentliziyo.

Eyona ixhaphakileyo sinus isingqisho okungaqhelekanga kwentliziyo. Eli qela libandakanya arrhythmias arrhythmia yokuphefumla, tachycardia sinus kunye bradycardia.

arrhythmia yokuphefumla ayikho zophendlo lwezifo kwaye kalula, ngelixa ukufunda ukubetha kwentliziyo nokuphefumla. Idla eyenzeka kubantu iimvakalelo, kunye nenkqubo labile luvo.

Malunga sinus tachycardia bathi ukuba izinga intliziyo kune-80 ngomzuzu. Le arrhythmia kuxhaphakile kubantu abasempilweni ngexesha umthambo, xa iimvakalelo ezinamandla, ukwanda obushushu. Khuphani olu hlobo arrhythmia nezifo - usuleleko, carditis, ukuwa yegazi kunye nezinye iimeko zophendlo lwezifo.

Ukuba izinga intliziyo ixhomekeke ubuncinane 60 - kwafunyaniswa sinus bradycardia. Bradycardia ngokuqhelekileyo eyenzeka leembaleki, abantu abenza umsebenzi wezandla, yaye maxa wambi kuyenzeka ngexesha ubuthongo. Ukuba uphuhliso karhulumente iziyobisi ezahlukeneyo sonyango, amagciwane, ngamanye amaxesha - iposi engabalulekanga.

Ukuze ufumane ezinye iingxaki intliziyo isingqisho esimbaxa ziquka arrhythmia ethunjini. Esona sizathu siphambili sokuba kwazo Ukwakheka kwamaziko ezongezelelweyo excitability kwi myocardium. Eli qela arrhythmias ziquka ibetha ngaphambi kwexesha, tachycardia paroxysmal, fibrillation atrial.

Linyuke of ubume inkqubo Uhanjiso kwentliziyo , okanye ukumisa ngokupheleleyo ukuqapha ebizwa. Kuxhomekeka ukuphazamiseka isabelo yaye kuvalwe ukwahlula sinus-atrial, atrioventricular, kwaye kuvalwe iindlela amasebe ngamnye umgodlo wakhe.

Njengoko ubona, intliziyo isingqisho eqhelekileyo ingahluka ngaphakathi kwemida ububanzi. Nokuxilonga utshintsho Intliziyo rate usebenzisa electrocardiogram. Ngokuqhelekileyo, abantu abadala - le akangaphandle esi sifo, kwaye iimpawu zizifo ezahlukahlukeneyo intliziyo kunye namanye amaziko. Ngoko ke, unyango arrhythmias zibangesiNgesi yonyango sifo ngxabano.
