ELEKTROKARDIOGRAFIYa

ELEKTROKARDIOGRAFIYa (az elektro, kardio… va grafiya), usuli tadqiqi mushakhoi dil tavassuti ba qayd giriftani potensialhoi bioelektrii dili korkunandaro guyand. Impulsi elektrikie, ki dar girehi sinusii dil paydo shuda, bad ba hamai miokard (mushaki dil) pahn megardad, ba vositai elektrokardiograf ba qayd girifta meshavad. Mulhanie, ki dar lentai qogazin yo fotonavori harakat kardaistoda aks yoftaast, elektrokardiogramma (mukhtasarai EKG) nom dorad. Vobasta ba on, ki elektronho ba kujoi badani odam guzoshta meshavad, samti jarayoni elektrik se kheli standarti (asosi) — I, II va Sh-yum, se kheli yakqutbi va shash kheli sinai (bo harfhoi V|— V6 ifoda mekunand) dorad. Dandonahoi EKG — bo harfhoi lotini: R, Q, R, S, T va U ifoda karda meshavand.

Elektrokardiogrammai boetidol se dandonai ba bolo (R, R va T) va du dandona i (Q va S) ba poyon nigaronidashuda dorad. Gayr az in fosilahoi PQ, QT, TR va RR inchunin kompleksi QRS, QRST-po farq, mekunand. Tahayyuji mushaki peshdil dar EKG chun dandonai R aks meyobad. Badi dandonai R fosilai PQ meoyad, ki on valyuta az peshdil to ba medacha rasidani impuls va cap shudani tahayyuji medachahoro nishon medihad. Kompleksi QRS alomi  tahayyuji medachaho buda, bad az on khati rosti ST meoyad. Hamai boloravandai dandonai T nisheb, nugash lundashakl va nimai ba pastnigaronidaash rost furomadagi meboshad. Fosilai QT tanosubi inqiboz (sistola)-i medachahost. Fosilai RR ba davomnokii vaqti yak davrai kori dil mutanosib ast. E. yake az muhimtarin usuli tadqiqi kasalihoi sistemam dilu ragho meboshad, Sarfi nazar az budan yo nabudani dandonaho, shaklu andozai onho, fosilai bayni dandonaho va g. ikhtiloli vazmi tappishi dil, bo khun taminshavii mushaki dil va az in ru layoqati kori dilro tashkhis menamoyand. Bo yorii E. (tavassuti ba har joi badan mondani elektrodhoi apparat) kadom qismi miokard oseb (mas., infarkt) yoftanashro muayyan mekunand.

E.-ro baroi tadqiqi tasirn doruho ba dili hayvonot labaratori, dar amaliyoti veterinari va tibbi sporti niz istifoda mebarand.
