What is the L’Onde U?

L’onde U est une onde qui fait suite habituellement à l’onde T et prend la même polarité (souvent, l’onde U fusionne avec l’onde T). L’onde T correspond à la repolarisation des ventricules (plus précisément la phase finale de la repolarisation ventriculaire), elle fait suite au complexe QRS dont elle est séparée par le segment ST.

What is L’Onde P in ECG?

L’onde P est la première onde détectable sur un tracé d’ECG, elle correspond à la contraction des oreillettes (dépolarisation auriculaire), vue la faible masse des oreillettes par rapport aux ventricules l’onde P est petite par rapport au complexe QRS.

What is L’Onde T in the QRS?

L’onde T correspond à la repolarisation des ventricules (plus précisément la phase finale de la repolarisation ventriculaire), elle fait suite au complexe QRS dont elle est séparée par le segment ST.

What is the net direction of the QRS complex?

Net direction of the QRS complex The QRS complex can be classified as net positive or net negative, referring to its net direction. The QRS complex is net positive if the sum of the positive areas (above baseline) exceeds that of the negative areas (below baseline). Refer to Figure 6, panel A.

What is the opposite direction of QRS?

Otherwise there is discordance (opposite directions of QRS and T) which might be due to pathology. A negative T-wave is also called an inverted T-wave. Figure 17. Discordance and concordance between QRS and ST-T. T-wave changes are notoriously misinterpreted, particularly inverted T-waves.

Does a QRS complex have a Q-wave?

If the first wave is not negative, then the QRS complex does not possess a Q-wave, regardless of the appearance of the QRS complex. All positive waves are referred to as R-waves. The first positive wave is simply an “R-wave” (R). The second positive wave is called “R-prime wave” (R’).

What is the QRS complex in ECG?

The QRS complex (ventricular complex): normal and abnormal configurations and intervals A complete QRS complex consists of a Q-, R- and S-wave. However, all three waves may not be visible and there is always variation between the leads. Some leads may display all waves, whereas others might only display one of the waves.
