The following table lists the prevalence of 7 diagnoses in patients suspected of having congenital heart disease.

The table uses the following abbreviations: ventricular septal defect (VSD), atrial septal defect (ASD) pulmonary stenosis (PS), pulmonary hypertension (PH).

The probability of having chest pain as a symptom given each diagnosis is presented in the third column.

So for example, the last line in the table indicates that the prevalence of VSD with PH is 0.126, and P(Chest pain | VSD with PH) = 0.10.

Diagnosis Prevalence Pr(Chest pain given diagnosis Normal 0.155 0.05 ASD without PS or PH 0.126 0.02 VSD with valvular PS 0.084 0.05 Isolated PH 0.020 0.10 Transposed great vessels 0.098 0.01 VSD without PH 0.391 0.01 VSD with PH 0.126 0.10
