In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
the contraction of the ventricles
A QRS wave is caused by the depolarization of the ventricles of the heart, which leads to the contraction of the ventricles and the pumping of blood out of the heart. The QRS complex represents the electrical activity associated with this depolarization.
No, the T wave is not higher than the QRS complex in this ECG reading.
The QRS complex on an ECG represents ventricular depolarisation. This wave should have the greatest amplitude.
The T wave in an ECG is typically in the same direction as the QRS complex because both represent ventricular depolarization and repolarization, respectively. During the QRS complex, the ventricles depolarize, and then during the T wave, they repolarize, leading to the similar orientation of the waves.
QRS-- A pattern seen in an electrocardiogram that indicates the pulses in a heart beat and their duration. Variations from a normal QRS pattern indicate heart disease.
There are a number of things that may happen during the QRS wave. There will be ventricular depolarization and right after absolute refractory period for ventricles will occur.
the repolarization of the atria is hidden by the QRS wave
QRS wave
The T wave is a component of the electrical activity of the heart that represents ventricular repolarization. It occurs after the QRS complex on an electrocardiogram (ECG) and indicates the resetting of the heart's electrical system in preparation for the next heartbeat. Changes in the T wave can indicate various cardiac conditions.
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
