Pulmonary Circulation — ECG/EKG Terminology

Definition: Flow of blood from the heart to the lungs and back to the heart.

Key Facts

• Moves blood from right ventricle to lungs and back to left atrium.
• Primary role is gas exchange rather than high-pressure perfusion.
• Pulmonary vascular pathology can acutely strain right heart function.

ECG Connection: Right-heart strain patterns can appear when pulmonary circulation is acutely compromised.

Why It Matters: Telemetry plus oxygenation trends can signal pulmonary-driven cardiac deterioration.
