Question | Answer |
isoelectric line before P wave equals | SA node firing |
P wave equals | atrial depolarization |
PR segment equals | av node delay, His, BBs, PFs |
QRS complex equals | ventricular depolarization, muscle cells depolarize |
ST segment equals | ventricular repolarization |
T wave equals | ventricular repolarization |
isoelectric line after T wave equals | resting phase; relaxation, filling |
