Editor’s Note:

So I was checking out some online posts on FB- and I saw a very cool image of a 3-D rendering of the conduction system of the heart.  I asked the person posting it- if they had a higher resolution picture for me to use here on ‘Surfers.

Well he didn’t, so i googled it and found a very cool link to an NIH pubmed site where the following images were retrieved.  You can visite the site by clicking the link below…

Happy Saturday guys 🙂

3-D Heart:  Conduction System

“Many heart anatomy models have been developed to study the electrophysiological properties of the human heart. However, none of them includes the geometry of the whole human heart. In this study, an anatomically detailed mathematical model of the human heart was firstly reconstructed from the computed tomography images.

In the reconstructed model, the atria consisted of atrial muscles, sinoatrial node, crista terminalis, pectinate muscles, Bachmann’s bundle, intercaval bundles, and limbus of the fossa ovalis. The atrioventricular junction included the atrioventricular node and atrioventricular ring, and the ventricles had ventricular muscles, His bundle, bundle branches, and Purkinje network.

The epicardial and endocardial myofiber orientations of the ventricles and one layer of atrial myofiber orientation were then measured. They were calculated using linear interpolation technique and minimum distance algorithm, respectively.

To the best of our knowledge, this is the first anatomically-detailed human heart model with corresponding experimentally measured fibers orientation. In addition, the whole heart excitation propagation was simulated using a monodomain model. The simulated normal activation sequence agreed well with the published experimental findings.”
