Node Sends Impulse Av Contraction  Bundle Electrical Sa

The heart beat's electrical conduction starts with the SA node stimulating atrial contraction, which triggers the AV node, followed by the Bundle of His conducting the signal down the septum to cause ventricular contraction.

The electrical conduction of a heartbeat begins with the SA node stimulating atrial contraction, which then triggers the AV node. The AV node sends a signal down the septum via the Bundle of His, which then innervates the ventricular wall, causing it to contract.

Original SA node sends electrical impulse stmulating myocardium contraction 
impulse causes arta to contract, stimulates AV node at junction between atrium and ventricle
AV node sends signal down septum via Bundle of His 
Bundle of His innervates nerve fibres in ventricular wall, causing contraction
