Effect of cardiac ventricular mechanical contraction on the characteristics of the ECG: A simulation study

abstract: the consequence of ventricular contraction on ecg profile (contraction --> ECG)

 

*method + result: 

-biophysical heart ( contraction + I_sac ) --> 3D torso Heart model --> 12 lead ECG compute

i) contraction + no I_sac : qrs에는 노 영향 , t-wave peak leftwards, amplitude up

ii) contraction + I-sac : QRS duration 23% up, q-t interval 5% up (t-wave 가 뒤로간다는말임)

 

*conclusion : contraction 은 QRS+T wave 에 영향있고 , 2. I_sac exacerbates
