p-wave is a wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.2 seconds (80-200 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node and the bundle of His.

The portion of the ECG that corresponds to atrial depolarization is the?

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.


What do P, QRS, and T waves represent in an electrocardiogram (ECG)?

The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).


What wave comes after the t wave of an ECG?

The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.


What does a segment of an ECG tracing indicate?

P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.


What do the letters PQRST represent?

P, Q, R, S and T each represent a wave of the electrocardiogram (ECG). The waves, and the ECG in general, confer a graphic representation of the hearth's electric activity. The ECG of a healthy person usually contains three waves, called the P wave, the QRS complex and the T wave. The P wave corresponds to the electric depolarization of the auricles, the QRS complex corresponds to the electric depolarization of the ventricles and the repolarization of the auricles, and the T wave corresponds to the electric repolarization of the ventricles. A complete period of an ECG (that is, the P, QRS, and T waves) represents the electrical activity of the heart for one pulse.


What is the ECG wave that results from the depolarization of the ventricle?

the P wave


What ecg curves represent recovery of the ventricles?

What are the differences between the T wave and P wave in an electrocardiogram (ECG)?

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.


What contraction of the atria results from which wave of depolarization on the ECG tracing?

P wave


What does the T wave in an ECG represent?

The T wave in an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.


What does the T wave on an ECG represent?

The T wave on an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.
