ABSTRACT
Objective:To explore the safety and efficacy of adenosine triphosphate (ATP) in terminating paro-xysmal supraventricular tachycardia (PSVT) in children and the correlation between its efficacy, age and dose.Methods:A retrospective analysis was performed on the clinical data, efficacy and adverse effects of intravenous ATP in 120 children who had received ATP emergency cardioversion among 1 488 children with PSVT hospitalized in the Department of Pediatric Cardiology, Heart Center, First Hospital of Tsinghua University from September 2014 to November 2019.There were 80 boys and 40 girls with the age of (3.50±3.66) years (25 d-15 years). As for the group comparison, the measurement data was subject to the independent samples t test and Mann- Whitney U test; the enumeration data was subject to χ2 test. Results:Among the 120 children with PSVT, there were 42 cases (35.0%) <1 year old, and 24 cases(20.0%) combined with congenital heart disease.There were 8.3% of them (10/120 cases) suffering from tachycardiomyopathy (TCM) secondary to PSVT, whose LVEF increased from (32.70±11.69)% to (40.50±11.63)% after successful control of PSVT ( t=-3.647, P=0.005). The complete termination of PSVT by intravenous ATP was achieved in 53 of 120 cases (44.2%). ATP was given at 0.3 mg/kg, 0.2 mg/kg and 0.1 mg/kg in dose, and the significant effective rate was 56.5%(13/23 cases), 36.4%(32/88 cases) and 0, respectively, which showed that there was a significant difference in the therapeutic effect between different dose groups ( χ2=10.058, P=0.007). There was a significant difference regarding the complete termination rate between children <1 year old and those ≥1 year old [31.0%(13/42 cases) vs.51.3%(40/78 cases), χ2=4.575, P=0.032]. For refractory PSVT, the intravenous ATP was performed based on the absence of cardioversion with continuous pumping of other antiarrhythmic drugs, which achieved a significantly complete termination rate of 55.6% (10/18 cases). The rate of ATP adverse reactions was 2.5%(3/120 cases), presented with sinus arrest in children >1 year old with the dose of 0.2-0.3 mg/kg. Conclusions:It was relatively safe and effective to terminate PSVT in children with ATP, which was related to dose and age.For refractory PSVT, ATP can be intravenously pushed on the basis of continuous pumping of other antiarrhythmic drugs, which can achieve a higher complete termination rate.
