Aorta — ECG/EKG Terminology

Definition: Largest artery in the body. Carries oxygenated blood from the left ventricle to the rest of the body.

Key Facts

• Largest systemic artery and primary outflow vessel from the left ventricle.
• Elastic wall stores systolic energy and helps maintain diastolic pressure.
• Branches provide blood flow to all major organs including the coronary arteries.

ECG Connection: Aortic pathology does not create a single ECG signature but may produce ischemic or strain changes.

Why It Matters: Hemodynamic instability with chest pain may reflect acute aortic or coronary pathology requiring escalation.
