Cardiac muscles don't contract in unison, if you listen to your heart beat you should hear two distinctive thumps (1 for the atria, 1 for the ventricles). I believe the structure you're looking for is the Sinoatrial Node (SA node) which is a bundle of nerves in the upper part of the right atrium, also known as the 'pace maker'. The electrical impulse from the node triggers a sequence of electrical events (from the SA Node to the A(trio)V(entricular) node to the Purkinje fibers) which are the cause of the beating/contracting
