Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
What generates the p wave of an electrocardiogram?
A P wave denotes atrial depolarization or when your atriacontracts. It is generated by the Sinoatrial (SA) node which is the primary pacemaker and signifies a Sinus Rhythm.
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 does P wave forms reflect?
A P wave reflects 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.
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
Why is the p-wave caused by atrial contraction?
The p-wave is the atrial depolarization or when the atrium contract to pump blood to the ventricles. The "p-wave" is showing you how the electic current changes while the heart is doing that specific action.
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
The p wave of a normal electrocardiogram indicates?
Atrial Depolarization.
On an electrocardiogram tracing atrial activity is represented by the?
p wave
What is the period when the atria are depolarizing?
atrial diastole
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.
