Ventricular amabhithi ngaphambi kwesikhathi: liphinde okwenzekayo evamile

Encwadini kwenhliziyo evamile usetha engeyokuqala ekhethekile sinoatrial, okungase atholakala ATRIUM kwesokudla. Ekhulula ngecala lokuvukela ugesi elibanga Atria ukwenza inkontileka. Yena ngokusebenzisa kwakha isimiso esiyinkimbinkimbi lamaseli ezikhethekile basakaza kanye myocardium. Imvamisa of Kufinyeta ulawulwa nezinzwa evamile futhi humoral ethize (catecholamines, isib, epinephrine) kahle. Ngakho inhliziyo avumelane nezidingo aphethe umzimba walo, okungukuthi, ngezikhathi zokucindezeleka, injabulo noma ngokomzimba ukuzikhandla imvamisa izinga iba olukhudlwana.

Beats - a "wedging" ka uthuthumele esengeziwe evamile isigqi inhliziyo, zingabantu - inhliziyo kokuvamile ukudala nobunzima ezengeziwe. Bona kwenzeke lapho i icala kagesi budluliselwe kusuka esifundeni ngaphandle engeyokuqala sinoatrial.

arrhythmias Supraventricular zenzeka ezimweni ezimbili. Noma uma abanye endaweni ATRIUM is depolarized ngaphambi kwesikhathi, noma uma umfutho okungavamile ithumela engeyokuqala atrioventricular. Ngo-60% abantu enempilo kukhona amabhithi ngabanye 'bayazalwa' kusukela ATRIUM. Nokho, ziyisici ejwayelekile izimo ezithile, njenge-isifo senhliziyo, futhi kwezinso of valve mitral. Abakwazi kushiya ukusikwa engalawuliwe - fibrillation, ngakho-ke angeke anganakwa esktrasistoly. Utshwala caffeine babhebhethekisa inkinga.

Ventricular amabhithi ngaphambi kwesikhathi kwenzeke kubantu zanoma iyiphi iminyaka. Akukhona neze engavamile. Uma ECG ukuqopha amahora 24 ke ama-63% cardiolog ezikhonjwe PVCs ngokuphelele enempilo olulodwa. Nokho, inani elikhulu lazo zitholakala abantu normal inhliziyo isakhiwo. Lokhu kwenzeka ngokuvamile ngemva kokushaywa yinhliziyo.

Izingane ventricular arrythmia kwenzeka mayelana kaningi umsebenzi njengoba atrial ngokuvamile ngokwanele njalo okujula ongaphakeme ukuthi isidlulile ukuvela. Kuphela uma isakhiwo okungavamile we Atria, kungabangela fibrillation atrial.

Kepha inhliziyo, okuyinto isakhiwo efanele, kumelwe kushiwo, akuyona esiyingozi ventricular arrythmia. Nokho, uma aqala avele kaningi ngesikhathi umsebenzi, kungcono kuwuphawu olubi.

Uma angahlangani Kutholwe isakhiwo, kufanele uvakashele wenhliziyo. isimo Kungenjalo wayesengaba zisongela ukuphila.

Engcupheni ukubonakaliswa amabhithi zihlanganisa umfutho ophakeme wegazi, ubudala avuthiwe, hypertrophy ventricular, isifo senhliziyo, zenhliziyo, ukuntula calcium, magnesium potassium, amphetamine, tricyclic antidepressant, futhi digoxin, ukusetshenziswa kabi kotshwala, ukucindezeleka, iziphuzo ezine-caffeine, kanye nezifo.

Ngokuvamile, iziguli esekhala palpitations. Ventricular amabhithi nisebancane wabonakaliswa entengo okungavamile emva umthelela evamile futhi kuhambisana umuzwa "ayeke" zenhliziyo. Kuyinto umuzwa ongavamile umuntu ezingajwayelekile, ngakho-ke Kuyaqapheleka njengoba uphawu. Abanye abantu ngesikhathi esifanayo ayinandaba kakhulu.

Ngokuvamile isimo wedwa siba sibi, futhi ngesikhathi umthwalo - ubabonisa uqobo. Nokho, uma umthwalo basuke eba namandla ngokwengeziwe, akusiwona ziwuphawu oluhle.

Futhi, zimpawu niphele amandla, amandla nokukhwehlela esingelapheki angeke sachaza ngamanye izimbangela.

Labo abaye esolwa inhliziyo anomalies izakhiwo echocardiography ababelwe ultrasound. Ihlola yegazi kanye nenani we-hormone yegilo, kanye nokwanela egazini electrolyte (calcium, magnesium, i-potassium). Ngokuvamile amasampula agcinwe umsebenzi ngokomzimba ophoqelelwe: imvamisa extrasystoles ihlolwe ngaphansi komthwalo futhi uphumule.

Ezimweni eziningi beats - hhayi imbangela alamu, kodwa uma usola kubo ngaleso - uya kudokotela obathembayo. zihlale zikhathazekile is yabulala abantu abangaphezu kuka amabhithi.
