Normal u wave
WebThe T wave follows the S wave, and in some cases, an additional U wave follows the T wave. To measure the QRS interval start at the end of the PR interval (or beginning of the Q wave) to the end of the S wave. Normally this interval is 0.08 to 0.10 seconds. WebU waves are usually best seen in the right precordial leads especially V2 and V3. The normal U wave is asymmetric with the ascending limb moving more rapidly than the descending limb (just the opposite of the normal T …

Web8 de dez. de 2024 · Nonspecific ST-T-wave changes are very common and may be seen in any lead of the electrocardiogram. The changes may be seen in all or most of the leads (diffuse changes), or they may be present contiguous leads, such as the inferior, lateral, or anterior leads. The types of abnormalities are varied and include subtle straightening of … WebThe normal T-wave is somewhat asymmetric, with a steeper downward slope. The U-wave. The U-wave, which is a positive wave after the T-wave, appears occasionally on the ECG. Its height (amplitude) is approximately one fourth of the amplitude of the T-wave. The U-wave is most often seen in leads V2, V3 and V4.
