The term regional wall motion abnormality or RWMA can be used in any imaging which shows movements of the myocardial segments like echocardiography, cine cardiac magnetic resonance imaging, cine computed tomography and nuclear cardiology imaging. The left ventricular myocardium has been divided into 17 segments by the American Society of Echocardiography . The true apex is a separate segment in this 17-segment nomenclature. In the previous 16 segment nomenclature, there is no separate true apical segment. True apical segment is beyond the left ventricular cavity towards the apex.
