Acute Pericarditis: Likelihood Ratios

Introduction: Inflammation of the pericardium, most commonly viral in nature though can also be caused by bacteria, uremia, tuberculosis, or autoimmune diseases (e.g. Lupus).

The likelihood ratios of findings for Acute Pericarditis are listed below. See the left navigation bar to change the display.

Pre-Test Probability (Prevalence): %. Post-Test Probability (Predictive Value): %. Switch to display mode.
**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
