Fig. 1

Twelve-lead electrocardiograms exhibiting PVCs arising from the APM and PPM. In patient 3 and 6, the PVCs have an RBBB pattern and right inferior axis, suggesting an origin at the APM. In patients 1, 2, 4 and 5, the PVCs morphology corresponds to an RBBB pattern and left superior axis, suggesting an origin at the PPM. PVCs, premature ventricular complexes; APM, anterolateral papillary muscle; PPM, posteromedial papillary muscle; RBBB, right bundle branch block
