The existence of left ventricular false tendons has been known for more than a century. Currently, the clinical entities associated with these left ventricular false tendons include innocent murmurs and premature ventricular contractions. A case report is presented where such a false tendon, attached to the interventricular septum, is responsible for striking ST-segment elevation in the anterior precordial leads. It is proposed that this is a newly observed entity that of subaortic tendon-induced ST-segment elevation. This is proposed as a totally benign phenomenon with the clinical importance in that it should not be confused with other pathological processes, such as the Brugada syndrome.en© 2009 Ker; licensee BioMed Central LtdST-segmentMyocardial infarctionInnocent murmursPremature ventricular contractionsLeft ventricular false tendonsHeart murmursTendons -- DiseasesMyocardial infarction -- DiagnosisArticle
