Electrical impulses originate uniformly within the Sinoatrial (SA) Node inside the right atrium, traveling smoothly through the Atrioventricular (AV) node and down the Purkinje network. This triggers a clean, organized, sequential muscular contraction from top to bottom.
Maintains optimal stroke volume and resting cardiac output. Systemic blood pressure and tissue oxygen perfusion remain perfectly balanced.
No intervention necessary. This represents a healthy, balanced physiological baseline state.
