WebThe bifid T wave can be confused with a T-U complex; however, unlike the U waves, the bifid T waves are usually present in most of the 12 ECG leads. LQT3 patients often show late-onset, narrow, peaked, and/or biphasic T waves with a prolonged isoelectric ST segment. Occasionally, the T wave is peaked and asymmetrical with a steep downslope. WebThe term “hyperacute T waves” is reserved for the early stages of MI. The presence of prominent T waves appearing to be “hyperacute” (ie, indicative of ischemia) is somewhat nonspecific and can also be found in patients with LVH, early repolarization, hyperkalemia, and a few other conditions.

WebHypokalaemia creates the illusion that the T wave is “pushed down”, with resultant T- wave flattening/inversion, ST depression, and prominent U waves In hyperkalaemia, the T wave is “pulled upwards”, creating tall “tented” T waves, and stretching the remainder of the ECG to cause P wave flattening, PR prolongation, and QRS widening 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.
