WebA high-voltage R wave (11 to 13 mm or more) is seen in lead aV L when the QRS axis is horizontal. (More rarely, when the axis is vertical, lead aV F may show a tall R wave exceeding 20 mm as part of a qR complex.) 3. Repolarization abnormalities include inverted T waves in leads with tall R waves. (Similar findings may occur with ischemia.) 4. WebLeft atrial enlargement is suggested by the presence of a notched, widened P wave of more than 2.5 mm or a biphasic P wave in V1. In contrast, a tall P wave of more than 3 mm in infants below 6 months and 2.5 mm in older children suggests right … soft serve ice cream ingredients

Web12 Apr 2024 · The R wave is the electrical conduction as it goes through the ventricle wall. They are thicker than the other heart muscle and need more electrical charge to do their work. This explains why the R peak is the highest seen on ECG. The R wave starts out small in lead V1 and gets progressively larger until around lead V4 and then becomes small again.
