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 portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
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).
Which part of the QRS complex represents the repolarization of the atria?
Which part of the QRS complex represents the repolarization of the atria?A.The Q waveB.The R waveC.The S waveD.None of the aboveThe S wave
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
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.
The QRS complex in an electrocardiogram results from?
An Electrocardiogram of a single heart beat shows three distinct waves. These are the P, QRS and T Waves. The QRS wave (normally the largest spike) in the electrocardiogram, is that of the ventricles depolarizing and contracting.
When is a p wave lost in the T wave?
this occurs with a premature beat known as a PAC (premature atrial contraction) A t wave is ventricular repolarization (the ventricle getting ready to beat again. A premature atrial contraction may happen at this time but you can discern the actual p wave as it is hidden in the t wave. Pac's are normal, most people have them occasionally. They can increase with stress, caffeine, smoking. The other cause would be in an irregularly fast arrhythmia in with the heart is beating so fast that the p wave is coming very close to the t wave and hard to discern it
What does the t wave represent on an ecg?
It represents the repolorization of the ventricles. The ventricles must reset electrically after contracting. In a normal Sinus Rhythm the p wave comes first. Then the QRS complex which is the largest part of the heartbeat will come less than .2 seconds later. The QRS complex usually lasts less than .12 seconds. The final bump is (usually) the T wave.
The T wave corresponds to the repolarization of the muscle fibers of the?
Ventricles
What portion of the ECG indicates ventricular repolarization?
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
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.
