Aortic Valve — ECG/EKG Terminology

Definition: Opens the way for oxygen-rich blood to pass from the left ventricle into the aorta, your body's largest artery.

Key Facts

• Opens during systole for left ventricular ejection into the aorta.
• Closes during diastole to prevent regurgitation into the ventricle.
• One of the two semilunar valves in the heart.

ECG Connection: Valve disease can lead to hypertrophy or ischemia patterns rather than a single diagnostic waveform.

Why It Matters: Monitor changes plus new symptoms may indicate decompensation in known valvular disease.
