Constrictive Pericarditis

Rapid early filling followed by abrupt constraint produces a dip-and-plateau pattern.

Overview

Select Constrictive Pericarditis under Clinical controls → Pericardial disease. The bold italic live label confirms the active selection. These are the preset’s teaching features; combined disease, rate and interventions can change the resulting numbers.

Rapid early filling followed by abrupt constraint produces a dip-and-plateau pattern.

RA has prominent x and y descents.

RV shows an early diastolic dip followed by a plateau.

Distinguishing constriction from restriction requires additional measurements, including simultaneous LV/RV respiratory behavior.

Step by step

  1. Reset interventions if you want the untreated example.
  2. Select the condition and inspect the pressure summary and relevant waveforms.
  3. Pause for annotations; add one intervention or loading change to compare the response.
