depolarization of atrial muscle fibers
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
the P wave
oops
The P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing in an ECG.
P wave
The key differences between the P wave and T wave in an electrocardiogram (ECG) are that the P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing.
ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.
The P wave.
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
