Treatment for Newborn with Frequent PACs

Initial Management Approach

• Newborns with frequent PACs and structurally normal hearts require observation only, without pharmacologic intervention, as they are benign and typically resolve spontaneously, according to the European Heart Journal 1
• Obtain a 12-lead ECG to confirm PACs and distinguish from other arrhythmias, particularly examining T waves carefully for blocked P waves that could simulate sinus bradycardia, as recommended by the European Heart Journal and Praxis Medical Insights 1, 2

Diagnostic Evaluation

• Consider 24-hour Holter monitoring to quantify PAC burden and identify any concerning patterns, as suggested by Praxis Medical Insights 3

Follow-Up Care

• Schedule follow-up ECG at 1 month to document resolution or persistence, as recommended by Praxis Medical Insights 2

Critical Pitfalls to Avoid

• Do not mistake blocked atrial bigeminy for sinus bradycardia by failing to examine T waves for hidden premature P waves—these have different clinical implications, according to the European Heart Journal and Praxis Medical Insights 1, 2
