nothing... a nonexistent Q wave represents a possible heart attack in the past in the location of whatever lead its in. However, patients that are barrel chested or just plain big can throw off an EKG.

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

the P wave


If you have an ECG conducted what causes the P wave?

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

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.


What part of the ECG records atrial contraction?

ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.


What does the pqrs wave mean?

The PQRS wave represents the electrical activity in the atria of the heart during an electrocardiogram (ECG). The P-wave indicates atrial depolarization, which is the contraction of the atria.


What part of the ECG complex represents the atrial depolarization?

The P wave.


What is the first wave of an ECG?

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


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).
