Right ventricular false tendons

Right ventricular false tendons (RFTs), also known as right ventricular muscular bands, are a much less well-known entity than left ventricular false tendons (LFTs). They are fibromuscular structures that arise from the inner trabeculated myocardial layer of the right ventricle, with a range of lengths and thicknesses ¹. Some right ventricular false tendons have been found to comprise of conducting tissue partially, and therefore may play a role in arrhythmogenesis ¹.
