The T-wave is the last wave in the pattern, with the U-point marking the end of the T-wave, after which the pattern starts over again at the next heartbeat’s P-point. New T-wave inversion means that if your T-waves normally curve upward (like a hill), they now curve downward (like a bowl). Lab testing

Web11. T Wave Abnormalities Introduction. The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below). WebThe T wave may be normally inverted or upright in III and in V1 (and in V2 in young people, and also in V3 in some Afro-Caribbeans). The T wave may be lengthened or made taller by electrolyte imbalances, especially potassium.
