Tricuspid Valve — ECG/EKG Terminology

Definition: Located between the right atrium and the right ventricle; it has three (tri-) leaflets, or cusps.

Key Facts

• Right atrioventricular valve with three leaflets.
• Prevents systolic backflow from the right ventricle into the right atrium.
• Right-sided volume overload can affect jugular and systemic venous findings.

ECG Connection: Right-sided chamber dilation from valve disease may alter P-wave and QRS morphology.

Why It Matters: Right-heart dysfunction can worsen oxygenation and perfusion in unstable patients.
