Compression of the heart caused by fluid collecting in the sac surrounding the heart.

Cardiac tamponade puts pressure on the heart and keeps it from filling properly. It causes a life-threatening drop in blood pressure.

Symptoms include anxiety, restlessness, and a sharp chest pain that worsens with deep breathing or coughing.

Emergency treatment is required. Usually, a needle or small tube is used to drain extra fluid.
