does a normal qrs complex measures <.12
In atrial fibrillation, the QRS complex is typically described as normal, but irregularly spaced due to the irregular heartbeat caused by the condition.
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.
A normal ECG of a human will show a P wave, QRS complex, and T wave. The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization. These waves correspond to the electrical activity of the heart during each phase of the cardiac cycle.
QRS complex
QRS
In an ECG showing atrial fibrillation (AFib), the rhythm appears irregular with no distinct P waves, and the QRS complexes may be normal. In contrast, a normal ECG rhythm shows regular intervals between heartbeats, clear P waves before each QRS complex, and consistent QRS complexes.
It is 90 degrees
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
