T Wave Inversion Causes, Symptoms And Treatment

WebTall or "tented" symmetrical T waves may indicate hyperkalemia. One of the earliest electrocardiographic finding of acute myocardial infarction is sometimes the hyperacute T wave, which can be distinguished from hyperkalemia by the broad base and slight asymmetry. T waves can be sharply pointed in ischemia as well. WebHyperacute T waves are first seen, which are tall, peaked, and symmetric in at least 2 contiguous leads. These usually last only minutes to an hour max.
