Which of the following is NOT a listed Group II condition in the WHO cardiovascular risk classifications?

• A. Most arrhythmias
• B. Repaired tetralogy of Fallot
• C. Isolated, ectopic beats
• D. Unrepaired AST

Answer: (C)

Isolated, ectopic beats are not a Group II condition because they are a common, benign finding in pregnancy that does not by itself create a measurable increase in maternal or fetal risk. The Group II category covers conditions with a small but definite risk that typically require more careful monitoring or specialized care. Repaired tetralogy of Fallot fits this, as even after repair there can be residual issues or arrhythmias that modestly raise risk. Most arrhythmias, depending on their severity and hemodynamic impact, may also fall into this category because they can contribute to increased risk. An unrepaired significant structural lesion would signal a higher risk level, not Group II. So isolated ectopic beats aren’t listed as a Group II condition.
