Paroxysmal supraventricular tachycardia (PSVT) is the most common pediatric arrhythmia. The objectives of this study were to determine the clinical features and treatment of PSVT in the emergency room and to evaluate the response to treatment and drugs employed. Methods: This is a retrospective study of 69 children admitted to the cardiology department of the Children's Hospital JM de los Rios from 2001 to 2011. Inclusion criteria: patients diagnosed with PSVT who were admitted to the emergency room. Results: 69 patients. Mean age: 5.9 years (SD ± 3.5). Two had a history of congenital heart disease (2.9%). The average heart rate was 284 beats / min (SD ± 30.66). The most frequent diagnosis was reentrant SVT, 35 patients (51%); the rest corresponded to Wolf Parkinson White syndrome. Five patients responded to vagal maneuvers. The treatment of choice in the acute crisis was adenosine. Electrical cardioversion was utilized in cases of initial treatment failure and hemodynamic inestability (16 patients). Maintenance treatment with beta-blockers and amiodarone was indicated in most cases (60.8%) with an effective response. Four patients required ablation, one of them relapsed. Conclusions: 1. clinical presentation of PSVT varies with age. 2. most patients responded to treatment with adenosine. 3. maintenance therapy with beta blockers and amiodarone is effective.
