Right Ventricle — ECG/EKG Terminology

Definition: The lower right chamber of the heart that receives deoxygenated blood from the right atrium and pumps it under low pressure into the lungs via the pulmonary artery.

Key Facts

• Pumps deoxygenated blood into pulmonary circulation under lower pressure than the left ventricle.
• Has thinner myocardium than the left ventricle because afterload is lower.
• Works in series with the left ventricle to maintain forward flow.

ECG Connection: Right ventricular activation is part of the QRS complex and can alter precordial morphology when abnormal.

Why It Matters: Right ventricular strain patterns can indicate acute cardiopulmonary deterioration.
