Web1 jan. 2015 · Characteristics of “true” juvenile T wave pattern include shallow inversions, limited to V1-V3/V4, an asymmetric morphology of the inverted T wave, and no significant ST segment deviation. For example, here is the ECG of a healthy 3 year-old female: Figure 3. We call these slightly asymmetric T-waves in V1-V3. WebThe Brugada syndrome may present with three different ECG patterns, referred to as type 1, type 2 and type 2 Brugada syndrome ECG. The most typical, and diagnostic, is type 1 Brugada syndrome. It features large coved ST-segment elevations and T-wave inversions in leads V1–V3. The coved ST-segment elevations may resemble a shark tale.
WebThe 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. Individuals with prominent T-waves display U-waves more often. WebBackground: We will focus our attention in this article in the ECG changes of classical Prinzmetal angina that occur during occlusive proximal coronary spasm usually in patients with normal or noncritical coronary stenosis.
