WebWhen the wave hits the fixed end, it changes direction, returning to its source. As it is reflected, the wave experiences an inversion, which means that it flips vertically. If a wave hits the fixed end with a crest, it will return as a trough, and vice versa (Henderson 2015). Refer to Figure 13.17. WebSep 3, 2014 · Hyperkalemia. ECG characteristics of hyperkalemia, high blood potassium: P-waves are widened and of low amplitude due to slowing of conduction. The initial part of the QRS complex is often spared as purkinje fibers are less sensitive to hyperkalemia. These changes can also occur in acidosis (via the same mechanism) and during Class IC anti ...

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).
