The basics of neonatal EKG interpretation

This article reviews the basic physiologic principles of the cardiac impulse and the EKG. It then relates these findings to the unique findings of the neonate and premature infant. Emphasis is placed on familiarizing nurses with the factors affecting the basic neonatal EKG and on the usefulness of cardiac rhythm strips and 12-lead EKGs. Topics addressed include evaluation of neonatal heart rate, examination of components of the cardiac cycle, identification of possible cardiac dysfunction, recognition of electrolyte imbalances, and effects of digoxin administration on cardiac rhythm.
