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 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.
Why is the R wave taller than the P wave on the ECG graph cycle?
The QRS complex is normally larger than the P Wave because depolarization of the larger muscle mass of the ventricles generates more voltage than does depolarization of the smaller muscle mass of the atria
How an ECG is obtained from a patient?
An ECG is obtained from a patient with a few (Possibly 6 or 8) Sticky pads, that are connected to the wires, connected to the ECG itsself, that are stuck onto the body in different places. These can read the heartrate and record it onto the ECG monitor and they will be printed off by a special printer.
What is the ECG of a normal human?
the electrocardiograph
What disease would affect an ECG?
heart disease
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 part of the ECG complex represents the atrial depolarization?
The P wave.
In an ecg pattern the p wave is caused by what?
depolarization of atrial muscle fibers
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
Which part is atrial systole in ECG?
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
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 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.
What are the main events recorded by an ecg?
The P-wave corresponds to atrial depolarisation.The QRS complex corresponds to ventricular depolarisation.The T-wave corresponds to ventricular repolarisation.
Atrial repolarization coincides in time with?
Atrial repolarization coincides with the QRS complex on the ECG. The T-wave corresponds to Ventricular repolarization. 'with tHE t-wave' <-- WRONG
What is the correct order of ECG waves?
P wave - represents atrial depolarization (contraction) QRS complex - ventricular depolarization T wave - ventricular repolarization (relaxation) atrial repolarization is "buried" within the QRS Complex
Why is the ECG event indicating atrial repolarization not seen in an 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 :)
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.
