What is the ECG wave that results from the depolarization of the ventricle?
the P wave
Depolarization of the sa node occurs during?
P wave
Is the left ventricle the first to depolarize?
No, the right ventricle is first to depolarize, that is if you're talking about ventricular depolarization (the QRS complex). If not, then it's the right atrium (atrial depolarization, P wave).
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.
Almost as soon as the depolarization wave begins a repolarization wave follows it across the membrane this occurs as?
This occurs as K+ diffuses out of the cell.
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).
Immediately before the P wave?
The electrical milestone event that occurs at the P wave of the cardiac cycle of the EKG is atrial depolarization. The upward stroke is right atrial depolarization, and the downward stroke is left atrial depolarization. Normally, this lasts for no more than 0.11 sec.
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.
The p wave corresponds to depolarization of the muscle fibers of the?
The p wave on a heart telemetry monitor represents the depolarization of the atria of the heart.
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.
Where on the cardiac cycle does a synchronized shock land?
A synchronized cardioversion shock is delivered a few milliseconds after the R wave on the EKG. The R wave represents ventricular depolarization, which is followed by mechanical contraction of the ventricle. Therefore, it can be seen that a synchronized shock will occur during ventricular contraction, or during ventricular systole, to completely depolarize the myocardium and try to restore a normal rhythm.
What does P wave forms reflect?
A P wave reflects atrial depolarization.
