In atrial fibrillation, the QRS complex is typically described as normal, but irregularly spaced due to the irregular heartbeat caused by the condition.
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.
In atrial fibrillation (a-fib), the EKG strip will show irregular and rapid heartbeats with no distinct P waves, while a normal EKG strip will show regular and steady heartbeats with clear P waves before each QRS complex.
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
Right and left atrial depolarization produce a P wave on an electrocardiogram (ECG) waveform. This represents the depolarization of the atria as they contract to push blood into the ventricles.
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.

Atrial paced
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.

the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
It is on page 374 of your lab book assuming this is the same question that came out Lab 28 in the Ninth Edition of Seeley's Anatomy & Physiology. The atrial repolarization occurs during ventricualr depolarization and is masked by the larger QRS complex. I actually did my homework :)
P wave - represents atrial depolarization (contraction) QRS complex - ventricular depolarization T wave - ventricular repolarization (relaxation) atrial repolarization is "buried" within the QRS Complex
On the EKG readout the P Wave represents atrial depolarization. For a healthy person it should be smooth, round and upright, and preceding the QRS complex.
An Electrocardiogram of a single heart beat shows three distinct waves. These are the P, QRS and T Waves. The QRS wave (normally the largest spike) in the electrocardiogram, is that of the ventricles depolarizing and contracting.
