CLINICAL CASE OF ATRIAL FLATTER TREATMENT IN NEWBORN

Abstract

Fetal atrial flutter (AFL) is the second most commonly occurring tachyarrhythmia diagnosed in lessthan 1% of pregnancies and accounts for up to 30% of all tachyarrhythmiain fetuses. TP is characterized by regular atrial contraction with a frequencyof 300-600 beats / min, accompanied by the same or less frequency of ventricular contractions due to different degrees of atrioventricular blockade, and 80% of the fetus es exhib it a blockadeof 2: 1. As the main mechanism leading to TP, the circle of re-entry is considered, which is caused by premature activation of the atrium. Clinical symptomatology, dueto TP, is determined by the frequency of ventricular contractions: from completeabsence of symptoms to congestive heart failure and death. The diagnosis of TP is confirmedby ECG, a holter study, the administration of adenosine. TP in fetus and newborn can stop spontaneously. Treatment for TP in volves an electrical or medication cardioversion, or atrial stimulation. The principles of treatment of fetuses and newborns with TP aregiven.The article describes a clinical case of diagnosis and treatment of atrial flutter in newborn.
