Taw qhia

Muaj ntau yam mob uas yuav tsum tau siv lub tshuab electrocardiogram, ECG lossis EKG, txhawm rau kuaj mob thiab kho kom raug. Ib qho electrocardiogram yog ntsuas kev ua haujlwm hluav taws xob ntawm lub plawv. Lub plawv cov leeg sib cog lus, uas ua rau lub plawv dhia uas tau hais los ntawm kev siv hluav taws xob uas ua tau zoo los ntawm cov kws kho mob.

Ib qho cuab yeej siv ECG ib txwm muaj, pom hauv tsev kho mob zoo thiab muaj txiaj ntsig zoo, raug nqi ntau txhiab daus las. Txawm hais tias cov no muab kev daws teeb meem zoo thiab raug rau kev nyeem ECG, cov cuab yeej no tsis tuaj yeem siv tau rau tus kheej, lossis tsev kho mob qis, thiab ntau qhov loj heev uas tsis suav nrog lawv los ntawm qhov thov kev saib xyuas.

Txhawm rau txhawm rau tawm tsam cov kev cov nyom nrog cov cuab yeej siv ECG ib txwm muaj, peb tsim cov ntsiab lus ntawm kev saib xyuas ECG lev. Qhov no yog qhov tsim pheej yig heev uas tsuas yog xav kom ib tus neeg tso lawv txhais tes rau ntawm lub lev, kos nrog ua ntej gelled bioelectrode sensors, txhawm rau kom tau txais ECG.

Lub ntsiab lus ntawm kev saib xyuas ECG lev yog nqa tau tag vim nws qhov me me thiab qhov tseeb tias tag nrho cov lev tuaj yeem siv tau los ntawm lub roj teeb me me. Cov cuab yeej no muab qhov pheej yig heev, nqa tau yooj yim, txhim khu kev ntseeg ECG nyeem ntawv.
