Human Heart Conduction System Anatomy - Electrical Pathway Illustration #64606 (License: Personal Use)

The image depicts a cross-section of the human heart with the conduction pathway traced in yellow, starting at the sinoatrial (SA) node in the right atrium, passing through the atrioventricular (AV) node, then down the Bundle of His, and branching into Purkinje fibers that stimulate ventricular contraction. The myocardium is shown in pink, with endocardial surfaces and major chambers clearly demarcated. This schematic emphasizes functional anatomy over precise histological detail.

Used in medical education, cardiology textbooks, patient brochures, and online health resources to explain how the heart generates and propagates electrical impulses for synchronized beating; targets students, clinicians, and patients seeking to understand arrhythmias or pacemaker function.
