What is Cardiac Tamponade? Cardiac Tamponade is a condition where the heart is compressed by fluid that collects around the heart, and this can happen by blood or even effusion. And because the fluid is in the pericardium, it will cause the compression of the heart, and this leads to decreased cardiac output, which happens due to the compression on the heart not allowing the heart to pump out sufficient blood.

What happens to diastolic pressure in all four champers during cardiac tamponade? There’s an equalization of diastolic pressure in all four champers in cardiac tamponade.
