The T wave in a electrocardiogram results from?
Repolarization of ventricular muscle fibers.
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
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.
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.
What is the difference between classic heart block and a u wave?
A heart Block is a non-conduction of an electrical pulse through the Bundle of His and a U wave is the repolarization of the Purkinje Fibers.
T wave corresponds to re polarization of the muscle fiber of the?
Relaxed
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 does the U wave represent on an ECG?
is the electrical activity generated by the contraction of the heart muscle
In an ecg pattern the p wave is caused by what?
depolarization of atrial muscle fibers
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 p wave on an ecg is described as a positive deflection that corresponds to what?
The P wave corresponds to the atrial contraction... the 'beat' of the upper chambers of the heart. The QRS complex correponds to the ventricular contractoins.. the 'beat' of the other two chambers. The T wave represents relaxation of the heart muscle.
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
