Normal Sinus Rhythm

Physiological Mechanism

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.

Hemodynamic Impact

Maintains optimal stroke volume and resting cardiac output. Systemic blood pressure and tissue oxygen perfusion remain perfectly balanced.

Clinical Treatment Protocol

No intervention necessary. This represents a healthy, balanced physiological baseline state.
