left ventricular contraction
does a normal qrs complex measures <.12
A QRS wave is caused by the depolarization of the ventricles of the heart, which leads to the contraction of the ventricles and the pumping of blood out of the heart. The QRS complex represents the electrical activity associated with this depolarization.
No, the T wave is not higher than the QRS complex in this ECG reading.
The ventricles contracting.
When ventricles depolarize
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
QRS complex
QRS
In atrial fibrillation, the QRS complex is typically described as normal, but irregularly spaced due to the irregular heartbeat caused by the condition.
Okay so an EKG show the electrical impulse that travels through the heart. What I mean is EKG don't show contraction. However the QRS complex represent ventricular depolarization, which signals ventricular contraction
