WebD wave: a positive or negative deflection in the electroretinogram occurring when a light stimulus is removed (off-response). WebR-wave amplitude in leads I, II and III should all be ≤ 20 mm. If R-wave in V1 is larger than S-wave in V1, the R-wave should be <5 mm. (1 mm corresponds to 0.1 mV on standard ECG grid). R-wave peak time. R …
WebAug 6, 2024 · A Q wave is a negative deflection before the R wave. The Q wave indicates the interventricular septum's usual left-to-right depolarization. Small 'septal' Q waves are often seen in the left-sided leads (I, aVL, V5 and V6) In most leads, little Q waves are typical. As a typical variation, deeper Q waves (>2 mm) may be found in leads III and aVR. WebAug 1, 2005 · Abstract. Objective: In the electrocardiogram (ECG) the U wave follows the T, which is considered to reflect the repolarization of the cardiac ventricles.Despite the U wave's well-known clinical relevance, a satisfactory explanation of its origin is still outstanding. We have undertaken to explain the formation of the U wave by means of a …
WebIt is represented on the surface ECG by a so-called Ta wave. The clinical relevance of this is that, although a normal phenomenon, the nadir of the Ta wave can occur just after the QRS complex and cause ST depression similar to (and easily mistaken with) that occurring with disease states such as cardiac ischaemia.
