May aid conduction system teaching in fixed hearts; leaves open validation in fresh tissue and clinical translation.
This simple dissection guide provides a practical method for identifying the cardiac conduction system, which is useful for anatomical education and understanding heart function.
Yanagawa et al. (2009) studied this question. Dissection method was evaluated on Identification of conduction system structures. A simple dissection method successfully identified the AV node, AV bundle, and right bundle branch in a formaldehyde-fixed human heart, though the SA node could not be found.
