Iyo yakajairika kurova kwemoyo ndeye 60 kusvika ku100 kurova mwoyo paminiti, nguva dzose. Izvo zvakare zvakajairwa kuti huwandu hwekurova kwemoyo kukurumidze mukuita kwekuita nesimba kana muchiitiko chekuderedzwa kwetachiona gland, semuenzaniso. A Mwoyo arrythmia kunoitika kana moyo inorova zvisina kujairika kana ikarova zvishoma pasi pemakumi matanhatu ekurova kwemoyo kana anopfuura makumi zana emwoyo paminiti, pasina chikonzero.

Arrhythmia ndiyo yakajairika moyo kusagadzikana. Mumoyo unogadzirira, iyo mafungiro emagetsi ndiani anodzora Mwoyo unorova kuitika kubva yakashata nzira kana usapfuure nepakati pemagetsi macircuit.

Iyo nguva ye arrhythmia inosiyana zvakanyanya kubva kune mumwe munhu kuenda kune mumwe uye zvakare kunoenderana nerudzi rwe arrhythmia.

taura pfungwa. Kune huwandu hwakawanda hwemhando dze arrhythmia, uye kwete ese anotsanangurwa mune ino pepa.

Mhando dzakasiyana dze arrhythmia

The arrhythmias dzinoiswa munzvimbo yainotangira, iyo atrium kana ventricle uye zvinoenderana nemhedzisiro yavanogadzira, kungave kumhanyisa kana kudzikira kwekurova kwemoyo. Iyo tachycardia inoenderana nekuwedzera kwemoyo, iyo bradycardies kusvika kuderera.

Tachycardias, kana kuwedzerwa kurova kwemoyo

Isu tinotaura nezve tachycardia apo moyo unorova pamwero mukuru kudarika zana kurova paminiti.

Dzimwe tachycardias dzinoitika mukati Mahedhifoni. Mafomu akajairika ndeaya:

• Atrial fibrillation. Ndiyo mhando yakajairika yearrhythmia. Inowanzoitika mushure memakore makumi matanhatu, mune vanhu vane yakakwira BP kana dambudziko remwoyo. Inowanzo kukonzerwa nekusakara uye kubvarura pane inoitisa nyama yemoyo. Kusvika ku60% yevanhu makumi masere uye pamusoro vanotambura nazvo. Nguva dzeatrial fibrillation dzinogona kutora kubva pamaminetsi mashoma kusvika kumaawa mashoma. Kazhinji fibrillation inotogara zvachose. Iyo fibrillating atrium inogona kubatika pamwero we10 kusvika 80 nguva paminiti (zvine mutsindo ma ventricles haarove nekukasira nekuti zvimwe zvezvinhu zvakashata zvinodzivirirwa munzira). Rudzi urwu rwe arrhythmia runogona kuve nengozi. Ropa harisisiri kutenderera zvakakwana. Kana ikamira muatrium, a kuvhara ropa inogona kuumba, kutamira kuuropi uye njodzi yekukonzera sitiroko;
• Atrial flutter. Rudzi rwe arrhythmia rwakafanana ne atrial fibrillation, kunyangwe kurova kwemoyo kwakanyatso kurongeka uye kunonoka zvishoma mune iyi kesi, kwakatenderedza mazana matatu paminiti;
• Tachycardia supraventricular. Kune akatiwandei mafomu. Iyo inowanzo kukonzera 160 kusvika ku200 contractions paminiti uye inogona kutora kubva pamaminetsi mashoma kusvika kumaawa mashoma. Inoitika zvakanyanya muvechidiki uye kazhinji haisi kutyisidzira hupenyu. Iyo inowanzozivikanwa ndeye supraventricular tachycardia Paroxysmal ou Chirwere cheBouveret (mhando pfupi yedunhu inogadzirwa uye inomutsa ma ventricles nekukurumidza uye kazhinji). iyo Wolff-Parkinson-White chirwere imwe fomu. Izvo zvinoitika kana simba remagetsi richipfuura kubva paatrium kuenda kune ventricle isina kupfuura nenzira yeatrioventricular;
• sinus tachycardia. Inozivikanwa ne yakawedzera kurova kwemoyo kudarika zana kurova paminiti. Sinus tachycardia yakajairika mumoyo une hutano mushure mekushanda nesimba, kushaya mvura, kushushikana, kudyiwa kwezvinokurudzira (kofi, doro, nicotine, nezvimwewo) kana mamwe marapirwo emishonga. Nekudaro, iyo dzimwe nguva inogona kuve chiratidzo chechinetso chakakura chehutano mumoyo, senge pulmonary embolism kana kutadza kwemoyo;
• Atrial extrasystole. Kuwedzeredza kwakatemerwa kusati kwasvika kwemoyo, kazhinji kuchiteverwa nekumbomira kwenguva yakareba kupfuura zvakajairwa. Iyo yekuwedzera dzimwe nguva inotsvedza pakati peyakajairika pulsations, pasina kuchinja kwavo kuteedzana. Zvakajairika kuva nezvishoma pazuva. Nezera, ivo vanowanzoitika, asi kazhinji vanoramba vasingakuvadzi. Nekudaro, ivo vanogona kukonzerwa nedambudziko rehutano (moyo kana zvimwe). Atrial extrasystole inotanga muatrium, nepo ventricular extrasystole (ona pazasi) inotangira kubva kuma ventricles.

Mamwe tachycardias anoitika mukati ventricles, ndiko kuti, mumakamuri epasi emoyo:

• Ventricular tachycardia. Uku kurova kwakajairwa, asi kuchikurumidza kwazvo kwema ventricles, kubva pa120 kusvika 250 contractions paminiti. Izvo zvinowanzoitika panzvimbo yekavara rakasiiwa nekuvhiya kwakapfuura kana kushaya simba nekuda kwechirwere chemwoyo. Kana iyo nguva ichinge yapera maminetsi akati wandei, inogona kudzikira kuita ventricular fibrillation uye inoda dambudziko rinopindura;
• Fibrillation ventricular. Izvi zvinokasira uye zvisina kurongeka kupokana kwemoyo ventricles zvinoumba a kurapwa. Moyo hauchakwanise kupomba uye neropa harichatenderera. Vanhu vazhinji vanorasikirwa nekuziva nekukasira uye vanoda rubatsiro rwekurapa nekukurumidza, kusanganisira cardiopulmonary resuscitation. Kurova kwemoyo kunofanira kudzoreredzwa nedhibhrifiya, zvikasadaro munhu anofa mukati memaminetsi mashoma;
• Syndrome du QT yakareba. Dambudziko iri rinoreva kureba kwenzvimbo yeQT pane electrocardiogram (ECG), inova nguva iri pakati pekuchaja magetsi nekubuditsa ma ventricles. Inowanzo kukonzerwa ne kusagadzikana kwemajini kana kuberekwa kwakashata kwemoyo. Uye zvakare, iyo mhedzisiro mhedzisiro yemishonga yakati wandei inogona kutungamira kune iyi syndrome. Izvo zvinoita kuti moyo urove nekukurumidza uye zvisina kujairika. Zvinogona kutungamira mukusaziva uye kunyange kukonzera kufa kamwe kamwe;
• Ventricular extrasystole. Premature contraction inogona kuitika muma ventricles. Ventricular extrasystole inowanzoitika kupfuura yeatrial mavambo. Sezvakaita atrial extrasystole, inogona kunge isina kukuvadza mumoyo wakagwinya. Nekudaro, izvo zvinodikanwa kuti uongorore zvimwe kana zvakajairika.

Bradycardias, kana kudzikira kwemwoyo

Bradycardia inoitika kana ropa richiparadzirwa kuburikidza pasi pemakumi matanhatu ekurova kwemoyo paminiti. Iyo inononoka kurova kwemoyo zvakajairika hazvireve hazvo kuti zvinotyisidzira hupenyu. Iyo inogona kutove chiratidzo cheakanakisa moyo hutano. Vamwe vatambi, semuenzaniso, vane zororo remwoyo wekurova makumi mana paminiti uye vanokodzera zvinoshamisa.

Kune rimwe divi, mune zviitiko apo moyo usingakwanise kupa zvakakwana nhengo ne oxygen, tinotaura nezvazvo chiratidzo bradycardia. Aya mafomu anotevera ndiwo akajairika.

• Sinoatrial node kusagadzikana. Izvi zvinowanzo kukonzera kurova kwemoyo kwepasi pe50 paminiti. Chikonzero chakanyanya kuvhunduka zvinyama zvinokanganisa kana kutsiva iyo sinoatrial node;
• Atrioventricular chinogumbura. Uku kukanganisa mukutapurirana kwesimba remagetsi (kunonoka, kumisidzana pano neapo kana kukanganiswa kwakazara) pakati peatria nema ventricles kunokonzera kudzikira mukurova kwemoyo.

Zvinokonzera

Zvinokonzeresaarrhythmia mwoyo akawanda uye anosanganisira anotevera:

• Kukwegura zvakajairika;
• Kushungurudzika;
• Kushungurudzwa kwefodya, doro, kofi kana chero chimwe chinhu chinokurudzira; kushandisa cocaine;
• Kupera mvura mumuviri;
• Arteriosclerosis uye atherosclerosis;
• Kutora mimwe mishonga;
• Broncho-pneumopathies (matambudziko nehurongwa hwekufema);
• Pulmonary embolism;
• Coronary insufficiency inotungamira mukushayikwa kwe oxygenation yemoyo tishu.

Zvinogona kuitika

Mimwe mhando ye arrhythmia inowedzera njodzi yezvinetso zvakadai se:

• tsaona yeperebrovascular (sitiroko);
• kutadza kwemoyo;
• a kurasikirwa kwekuziva (kashoma, chete mamwe marudzi e arrhythmia).

Nguva yekubvunza chiremba?

Bata navo mabasa ekukurumidzira ipapo kana iwe ukaona zviratidzo zvakadai sekurova kwemoyo, chipfuva chepfu kana kushaya mweya, zvisingatarisirwi uye zvisina kutsanangurwa.
