Webb10 feb. 2024 · T-wave changes. The most common T-wave abnormality is a biphasic T wave with an initial negative deflection and terminal positive deflection. This is usually seen in leads with a dominant R wave (e.g. V4-6). The first part of the T wave is typically continuous with the depressed ST segment. Webbaccording to some other authors, with a slurred termination of the QRS complex [1,2]. Figure 1 illustrates QRS slurring and notching.

WebbThere should be a terminal R wave in lead V 1 (often called "R prime," and denoted by R, rR', rsR', rSR', or qR). There must be a prolonged S wave in leads I and V 6 (sometimes referred to as a "slurred" S wave). The T wave should be deflected opposite the terminal deflection of the QRS complex.

The U wave is a small, low-frequency diastolic deflection that begins usually with the second heart sound at the onset of ventricular relaxation and after the end of the T wave.65 The T-U junction is situated at or close to the isoelectric baseline, but it may be slightly depressed or slightly elevated. WebbT-Wave Analysis Mostly positive in most leads, with amplitude decreasing with increased age. The ST segment transition to T-wave should be smooth. It can be asymmetrical, as it has a slight upslope (1st half) and downslope (2nd half). T-Wave changes are easily misinterpreted (mostly inverted T-waves), so take caution. trading economics japan stock market
