The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy. The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy. Potassium was 4,8 mmol/l. ( ref 3,5-4,6 mmol/l ).

As a result, in order to differentiate MAT from the much more commonly encountered irregularly irregular rhythm ( which is AFib ) — we need to be certain we are seeing multiple different P wave morphologies that are constantly changing. Clinically , the importance of recognizing MAT — is that treatment is different than the treatment of AFib.
