Group II typically includes which of the following conditions?

• A. Most arrhythmias
• B. Isolated ectopic beats
• C. Small uncomplicated PDAVSD
• D. Repaired ASD with no residuals

Answer: (A)

Group II is defined by the predominance of rhythm disturbances in pregnant patients with congenital heart disease. Arrhythmias, including tachyarrhythmias and conduction abnormalities, are a common and clinically significant issue that can arise across various CHD lesions and after surgical repairs. Pregnancy-related hemodynamic changes—increased blood volume, heart rate, and hormonal influences—can amplify these rhythm issues, making arrhythmias the characteristic problem in this group. In contrast, a small uncomplicated PDAVSD or a repaired ASD with no residuals represent simple, stable lesions with minimal hemodynamic impact and do not typically drive a Group II profile; they are usually managed as lower-risk conditions. Isolated ectopic beats are often benign and may be considered within normal variants rather than a defining feature of Group II. Therefore, most arrhythmias best describe Group II.
