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 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?
oops
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
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 part of the ECG complex represents the atrial depolarization?
The P wave.
What are the 3 components of the ECG trace?
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).
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 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 part of an ecg do atria contract?
Atrial depolarization occurs at the P wave. The atrial contraction occurs at the peak of the wave at the influx of calcium ions to prolong depolarization.
The p wave of the electrocardiogram is a signal from?
The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
What does the P wave indicate?
The P wave indicates the depolarization (contraction) of the atria.Source: Chon, Elizabeth Gross, and Gilroy-Doohan, Mary,Flip and See ECG, W.B. Saunders Company
