Background: Apical hypertrophic cardiomyopathy (AHCM) is a relatively rare variant of hypertrophic cardiomyopathy. The condition is associated with numerous clinical and electrocardiogram (ECG) features, some of which are well documented in the literature.
Case Presentation: We present a case of a 77-year-old female who presented with a syncopal episode. Her ECG showed lateral ST segment elevation and her cardiac biomarkers were not in keeping with a myocardial infarction. She was diagnosed with AHCM based on characteristic findings on echocardiography. The association between AHCM and lateral ST segment elevation is one that has only been described in a handful of cases in literature.
Conclusion: The authors hope that in presenting this case we can add to the body of literature and remind readers to be aware of the possibility that lateral ST segment elevation may be an indicator of AHCM, especially when this electrocardiographic feature occurs in the absence of the other well-known causes of ST segment elevation.
