Figure 2From: Non-invasive visualization of the complete cardiac conduction system using magnetic resonance microscopyRepresentative data set from rabbit heart showing fiber tracking of the conduction network from base to midwall (A → D). The conducting network originates behind the non-coronary leaflet at the base (A) and quickly bifurcates (B) into fibers that proceed down the right ventricular subendocardium (shown in blue) and a branch that continues along the septum for a short distance before continuing down the left ventricular subendocardium (C, D) in a fan-like structure (shown in purple). The fan-like structure terminates in free-running Purkinje fibers in the left ventricle. Data from conducting fibers that are more apical has been omitted for clarity.Back to article page
