  In pericarditis, the R atrium going –> R ventricle having fibrous tissue (imagine having hard robber wall around RV) prevent ventricle to expand.
When RV contract & then relaxes (blood leave RA -> RV) IT’s going to go down V->Y very quickly. But ASA that RV fills up there would be no room for that RV to expand -> you get sharp demarcation back on “Y” back up again, so in fact in pericarditis you get VERY SHARP accentuated “Y” descent as it descends from higher than norm RA/P [ aka; square root wave/sign], now X descent becomes a bit accentuated.
