Dzimwe nguva chironga chemwoyo chinogona kukonzerwa nechizvarwa chinokanganisa chemagetsi asinganzwisisiki kubva kune imwe nzvimbo mukati memwoyo. Apo izvi zvinokanganisa zvinowanzoitika nokukurumidza, tachycardia (inokurumidza kutsva mwoyo) inoitika. Tachycardias inokonzerwa nechizvarwa chinokanganisa chemagetsi asingazivikanwi anonzi "automatic tachycardias."
Zvinokonzera
Izwi rokuti tachycardia rinongoreva chiyero chemwoyo chepamusoro pekurohwa 100 paminiti.
Pane zvikonzero zvitatu zvinokonzera tachycardia:
- Kazhinji tachycardia (kana sinus tachycardia) ndeyechiitiko chinowanzoitika vazhinji vedu tinoona zuva rimwe nerimwe. Izvo zvinoitika nokuti node ye sinus inokurumidza kusvika pachiyero iyo inokonzera mafungiro emagetsi maererano nekuedza kana kushungurudzika. (Kune, zvisinei, rudzi rwechiito chisina kujairika tachycardia, chinonzi sinus sinus tachycardia, kana IST .)
- Kudzorera tachycardia chirongwa chemwoyo chinokonzerwa nekushamwaridzana kwemagetsi kune imwe nzvimbo mumoyo iyo inogadzira dunhu rinokwanisa. Kudzorera tachycardias kutanga uye kumira kamwe kamwe uye pasina chikonzero chakajeka, uye kazhinji kazhinji kunoitika kune vanhu avo vangave vane utano hwakakwana.
- Kushandura tachycardias hakurevi magetsi eruwa asi asi, kunokonzerwa nechizvarwa chinokanganisa chemagetsi emagetsi kubva pane imwe nzvimbo kunze kweropa re sinus. Aya magarthmias anowanzoonekwa kuvanhu vane mishonga isina kugadzikana.
Mamiriro
Muchizvidzivirira tachycardias, masero mune imwe nzvimbo mukati memwoyo anotanga kubudisa mafungiro awo emagetsi zvakakurumidza kupfuura node ye sinus inosvika, nokudaro kutora rwiyo rwemoyo nekubereka tachycardia.
Zvichida tachycardias inogona kunge iine supraventricular (inonzi "automatic atrial tachycardia," zvinoreva kuti masero "ari nyore" kupisa anowanikwa mukati meatria), kana kuti ventricular ("automatic ventricular tachycardia," umo kusagadzikana kwemagetsi ari kuuya kubva kuvhudziro).
Mukuwedzera, zvinowanzoitika junctional tachycardia zvinogona kuitika kana mafungiro asina kufanira achiuya pedyo neAV node , iyo iri pedyo ne "junction" yeAria uye ivhu).
Kusiyana zvakasiyana nevezve reach tachycardias, zvinowanzoitika tachycardias zvinowanzoonekwa kune vanhu vari kurwara zvikuru. Izvi ndezvokuti mhando dzakasiyana-siyana dzehutachiona hunogona kuumba mamiriro ezvinhu anodikamwa kuti mwoyo uve nemafungiro asina kunaka emagetsi.
Kunyanya, zvinogadziriswa arrhythmias zvinowanzoitika kune vanhu vane acute mapapu chirwere (zvakadai seplumine embolus kana pneumonia), achirwereka myocardial infarction (kurwadziwa kwemwoyo) , kana kune vanhu vane zvakasiyana-siyana zvakakomba mumamiriro avo emagetsi - zvakadai sechitsipa chemuviri weropa mazinga, low potassium kana kuti magnesium ropa mazinga, kana zvakakwirira zvikuru zveadrenalin.
Somugumisiro, tachycardias dzinowanzoonekwa muvanonyanya kusagadzikana muchipatara, kunyanya kune vanhu vanorwara zvakakwana kuti vave mune zvipatara zvakanyanya.
Kune zvipfeko kune iyi inowanzo, asi. Chinhu chisingawanzozivikanwa chinonzi automatic atrial tachycardia (inonziwo "ectopic atrial tachycardia") inogona kuitika kune vechidiki, vamwe vanhu vane utano hwakanaka. Kusiyana nekudzokazve kweatricycardia, chirwere ichi chinoita kuti chirambe chichienderera mberi panzvimbo pechipfuva uye chinogona kutungamirira ku tachycardia-induced heart failure.
Mhando iyi yekuramba iripo inouraya tacycardia inowanzobatwa nehutachiona hwekubvisa .
Kurapa
Nenzira yakawanda, kurapa kwakanakisisa kwekutengesa tachycardia ndiko kuziva uye kudzosera dambudziko rekurapa riri pasi. Kana imwe nguva mapapu ari pasi, chirwere chemwoyo, kana kusagadzikana kwemagetsi kunogadziriswa, chirongwa chechirmemia chinoenda. Saka munenge mamiriro ezvinhu ose, kurapwa kwevatachiona tachycardias ndekukurumidza kugadzirisa chirwere chekurapa chiri kurichiita.
Kazhinji, kana munhu ane tachycardia yega-oga ane utano hwakakwana zvokuti abve muchipatara, chirongwa chacho chakatozogadziriswa.
Hapana chikonzero chekutarisa kushandiswa kwemishonga isingagadziriswi, kana mamwe maawa ekugara kwenguva yakareba inotarisirwa mukurapa mwoyo arrhythmias. Kuchengetedza chero mamwe magwaro ekutonga nyaya yekutora chero matanho aunokwanisa kuita kudzivirira kudzokorora kwehutano hwehutano hwakakonzera chirongwa chekutanga mune.
Shoko Rinobva
Automatic tachycardias inokonzerwa nechizvarwa chinokanganisa chemagetsi kubva kune imwe nzvimbo mumoyo. Zvinogona kufungidzirwa sechirongwa chemwoyo chinokonzerwa ne "shungu" yemasikirini emwoyo, kazhinji semugumisiro wechirwere chakaoma, chirwere chakanyanya. Nenzira yakawanda, aya arrhythmias anoenda apo chirwere chepachirwere chepachirwere chinobudirira zvakaporesa, uye hapana chirwere chekare chinonzi antiarrhythmic therapy chinodiwa.
