“…El tratamiento postnatal más empleado en el flutter auricular es la cardioversión eléctrica sincronizada 4,9 . A diferencia de lo ocurrido en los casos primero y tercero, la recidiva neonatal del flutter auricular es poco habitual y, en general, no precisa tratamiento profiláctico 2,5,9 ; además, su asociación con vías accesorias es excepcional.…”

“…6 The gender distribution of AF seems to be equal. 3 AF is generally well tolerated, and association with fetal hydrops or death is rarely encountered. 6 The majority of fetal rhythm disorders detected before week 36 of gestation can be treated by maternal administration of antiarrhythmic drugs such as digoxin or dexamethasone.…”

“…AF is an arrythmia based on a macro-reentry mechanism, present within the atrial wall, with a variable conduction to the ventricles, and does not include the atrioventricular node. 3,9 As the cardiac output is directly influenced by the ventricular rate, a very rapid ventricular depolarization may lead to a sudden decrease in the stroke volume and thus to acute heart failure. 10 The rapid atrial contractions with secondary blood pooling can be responsible for thrombus formation and may lead to embolic events.…”

“…2 AF represents about 32% of all neonatal cardiac arrhythmias, and it is based on a reentry mechanism. 3 AF is usually diagnosed on the electrocardiogram (ECG) in the presence of typical saw-tooth flutter waves that are best seen in leads II, III, and aVF. Atrial rates vary between 280-450 beats per minute (bpm), frequently accompanying a 2 : 1 atrioventricular conduction and a ventricular response ranging from 150 to 250 bpm.…”

Introduction: The incidence of cardiac arrhythmia is approximately 1% in the neonatal period and 1–3% in late pregnancy. Atrial flutter (AF), a rhythm disorder based on the mechanism of reentry, represents approximately 32% of all neonatal cardiac arrhythmias. In the majority of cases, the flutter is converted to sinus rhythm using antiarrhythmic drugs, transesophageal overdrive pacing, or synchronized electrical cardioversion.Case presentation: We present a case of a born on term, female infant who was noted to be tachycardic on the fetal monitor. Clinical examination revealed tachypnea and tachycardia with dysrhythmia, at a heart rate of 250 bpm. Electrocardiography showed AF with 2–3 : 1 atrioventricular conduction (atrial and ventricular rates were 350 bpm and 250–275 bpm, respectively). Echocardiography revealed no relevant structural disease. Therapy with amiodarone and prophylactic anticoagulant was initiated. As no control of ventricular rate was obtained and a succession of three ventricular extrasystoles was noted on the surface ECG, propranolol therapy was initiated, without success. Therefore, synchronized electrical cardioversion was applied, with conversion to sinus rhythm at a heart rate of 136 bpm. The neonate was discharged in good condition.Conclusions: AF is one of the most common high ventricular rate arrhythmias during fetal age. Uncontrolled AF may precipitate heart failure, and prompt restoration to sinus rhythm may require electrical cardioversion in cases refractory to anti-arrhythmic drugs, in order to prevent possible complications.

Background: Non-benign arrhythmias, which require urgent recognition and care in neonatal intensive care unit (NICU) settings, are rare but can severely impact neonates. We aimed to clarify the epidemiology and characteristics of non-benign arrhythmias and their influence on neonates. Methods: This single-center retrospective study included patients admitted to the NICU at Kurashiki Central Hospital between January 2001 and December 2019. Only patients with structurally normal hearts were included. The use of direct cardioversion (DC), antiarrhythmic agents, and the presence of risk factors was reviewed from medical records. Results: Of the 8082 admissions, 2919 patients (36.1%) were low birth weight infants (LBWI) weighing less than 1500 g. There were 23 patients with arrhythmias (nine of them were LBWIs) with an incidence of 0.28%. There were 16 patients with tachyarrhythmia (eight supraventricular tachycardia [SVT] cases, three atrial flutters [AFL]cases, three ventricular tachycardia cases, two junctional ectopic tachycardia cases), and seven with bradyarrhythmia (all with complete atrioventricular [AV] block). For tachyarrhythmia cases, seven patients required DC, and eight were on antiarrhythmic agents at the time of discharge. Two patients (28.5%) with complete AV block required pacemaker implantation before discharge. The treatment strategy was dependent on the type of arrhythmia. All patients were discharged without significant morbidities. Conclusions:The incidence of non-benign arrhythmias was as low as 0.28%.Arrhythmias can be managed successfully in neonates, yet risk factors related to mortality warrant further study.
