in paced hearts, the ecg shows a sharp spike just before the qRs or R wave and the R wave will usually be widened if the ventricle is being stimulated directly. Similar to the appearance of the R wave in patients with complete heart block.

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 wave comes after the t wave of an ECG?

The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.

the P wave


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


Is the T wave higher than the QRS complex in this ECG reading?

No, the T wave is not higher than the QRS complex in this ECG reading.


Why is the T wave positive in the ECG?

The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.


What does the T wave in an ECG represent?

The T wave in an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.


What does the T wave on an ECG represent?

The T wave on an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.

The T wave in an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.


What are the differences between the T wave and P wave in an electrocardiogram (ECG)?

The P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing in an ECG.


What contraction of the atria results from which wave of depolarization on the ECG tracing?

P wave


What is QRS in ECG?

The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
