At pericarditis or tamponade, there is an obstacle for intake from the atria to the ventricles. Due to the obstruction from outside, eg by pericardial fluid, so that the space in which the heart is restricted, filling of one ventricle will be detrimental to the area of the other ventricle. When inhaling the filling of the right ventricle does at the expense of the filling of the left ventricle. This is called interdependence. When tamponade is outside pressure causing this effect is much more to the ground compared with constrictive pericarditis with early diastolic filling is not obstructed. Throughout the diastolic filling This is also the reason why a tamponade almost always Pulsus paradoxus is found only rarely in a constrictive. | At pericarditis or tamponade, there is an obstacle for intake from the atria to the ventricles.

Inhalation decreases intrathoracic pressure, the pressure longveneuse this will also decrease, however intrapericardially located diastolic LV pressure is not falling. In other words, by inhalation reduced the pressure gradient between the pulmonary veins and left which will take off.
