A case report illustrates competing explanations for cardiac findings after a seizure and several medication changes.
A complex sequence
A hospitalized woman had a generalized seizure terminated with lorazepam and then received phenytoin. QT prolongation led to holding methadone. A later ECG showed diffuse deep T-wave inversions, initially considered medication-related. The authors subsequently favored stress cardiomyopathy associated with the seizure.
The favored explanation remained inferential
This was one clinical case without a controlled way to isolate each contributor. Treatment appearing before an abnormal ECG does not prove it caused the change, while a plausible seizure mechanism does not eliminate every alternative. The paper supports rebuilding the timeline of seizure activity, ECGs, medications, and cardiac investigations. It cannot quantify lorazepam’s cardiac risk or establish that all post-seizure repolarization changes have the same cause. Objective findings and alternative explanations should remain visible in any attribution.
