The association of an ecg low "T" wave with chest pain can be related to hypomagnesemia and hypokalemia.
T-wave abnormalities by their own, without the detection of chest pain or similar such symptoms, are neither conclusively proven of any harm, nor a sign of problem in future. It is only when these accompany pains, that a doctor consider it as an alarming development. Results support the concept that hypomagnesemia is common in patients with chest pain in the emergency department and is associated with hypokalemia but is not predictive of whether the patient with chest pain has had an acute myocardial infarction.
