Case ReportsBlocked atrial bigeminy presenting with bradycardia.
Blocked premature atrial contractions can cause bradycardia by resetting sinoatrial node and prolonging the RR intervals. Herein, we report the management of a patient with frequent premature atrial contractions in bigeminal pattern. The patient presented with symptomatic bradycardia and was successfully treated with propafenone.

Pulse oximetry can be used as a screening tool to detect critical congenital heart disease (CCHD) in neonates prior to hospital discharge and the development of symptoms. Newborns suspected of having CCHD based on pulse oximetry screening should have the diagnosis excluded or confirmed with echocardiography. However, echocardiography is not immediately available in all settings in which newborns are delivered and the best course of action in these settings remains to be determined. The purpose of this study was to evaluate the resources available to diagnose and treat newborns with CCHD born in the state of Wisconsin. ⋯ Pulse oximetry is universally available in Wisconsin newborn nurseries, and pulse oximetry screening for CCHD is currently being performed for many of Wisconsin's newborns. The majority of births in Wisconsin occur in hospitals where same-day neonatal echocardiography is available for confirmatory diagnosis of CCHD when necessary.
