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
What is QRS in ECG?
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
Which phase of the ECG indicates ventricular excitation and contraction?
The QRS complex
When the ventricular walls contract the?
in an ECG pattern, the T wave is caused by
Does the atrial rate equal the ventricular rate in the ECG tracing?
yes
Deflection waves in an ECG tracing include?
the T wave, which indicates ventricular repolarization
The deflection waves in an ecg tracing include?
the T wave, which indicates ventricular repolarization.
What is the difference between heart rate and ventricular rate?
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
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.
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.
The R wave of the ECG is most closely associated with which phase of the cardiac contraction cycle?
Ventricular contraction.
What change in polarization is the t waves on an ecg tracing?
t wave just appears before the ventricular relaxation
