Ntxiv nrog rau muab kev pom rau lub plawv dhia, lub ECG pab koj tus kws kho mob txiav txim siab qhov loj ntawm chav hauv plawv, txheeb xyuas cov leeg nqaij puas tsuaj thiab txheeb xyuas qhov txawv txav ntawm qee yam zaub mov hauv ntshav, xws li potassium thiab calcium, uas hloov pauv ECG.
Hauv qhov no, ECG tracing sawv cev li cas?
Qhov kev siv hluav taws xob no tsim los ntawm lub plawv tuaj yeem ntsuas los ntawm cov kab hluav taws xob tso rau ntawm lub cev. Cov kaw taug qab npe a electrocardiogram tshuaj xyuas ( ECG , los yog EKG ). Cov nthwv dej sib txawv uas suav nrog ECG sawv cev Qhov sib lawv liag ntawm depolarization thiab repolarization ntawm atria thiab ventricles.
Qhov ib txwm ECG kab mob zoo li cas? Li qub ntau 120 - 200 ms (3 - 5 me me squares rau ECG ntawv). Li qub ntau txog 120 ms (3 me me squares rau ECG ntawv). QT ncua sij hawm (ntsuas los ntawm thawj deflection ntawm QRS complex mus rau qhov kawg ntawm T yoj ntawm isoelectric kab). Li qub ntau txog 440 ms (tab sis nws txawv nrog lub plawv dhia thiab tej zaum yuav ua ntev me ntsis hauv cov poj niam)
Cov lus nug tseem yog, qhov ST ntu hauv ECG tracing qhia li cas?
Nyob rau hauv electrocardiography, lub ST ntu txuas QRS complex thiab T yoj thiab muaj Lub sijhawm ntawm 0.005 txog 0.150 sec (5 txog 150 ms). Cov ST ntu sawv cev rau lub sijhawm isoelectric thaum lub ventricles yog nyob rau hauv nruab nrab ntawm depolarization thiab repolarization.
