Abstract
Congestive heart failure due to atrial tachycardia in the neonate may be caused in part by altered preload and changes in diastolic flow cha racteristics. During atrial tachycardia, venous flow reversal is prese nt. Onset of flow reversal is associated with a ventriculoatrial inter val. Decreased tricuspid valve inflow mean velocity and time velocity integral, decreased diastolic duration, and delayed diastolic onset we re present during tachycardia when compared with sinus rhythm.
