| Objective:Paroxysmal supraventricular tachycardia (PSVT) is a common pediatric disease, however, the diagnosis and treatment for PSVT in infants is more difficult. This research review on from1996to2006hospitalized infants and study of the clinical diagnosis and treatment in infants with paroxysmal supraventricular tachycardia.Method:31cases of infants hospitalized from1996to2006with paroxysmal supraventricular tachycardia including clinical manifestations, the heart rate at the time of attack, its complications and drug treatment were analyzed. Electrocardiogram (ECG) was performed to diagnose and anti-arrhythmic drug therapy was given to the patients.Result:At the time of paroxysmal supraventricular tachycardia attack restlessness, refusing milk, pallor, difficulty in breathing were observed; average heart rate of260beats/min was recorded, out of which15cases with acute congestive heart failure and7cases with cardiogenic shock were noted.In infants with PSVT after given propafenone, adenosine triphosphate (ATP), intravenous amidarone sinus rhythm was quickly recovered; infants with cardiac insufficiency firstly were given digoxin18h fast saturation to recover the normal heart rhythm then application of anti-arrhythmic drugs used to maintain the rhythm. For infants with cardiogenic shock, apart from digoxin; combination of dopamine and sodium nitroprusside was applied to improve cardiac function; after application of anti-arrhythmic drug therapy leads to safe recovery.Conclusion:PSVT in infants with inconspicuous symptoms, episodes of rapid heart rate, acute congestive heart failure; firstly given digoxin18h fast saturation, after the improvement of cardiac function then only apply anti-arrhythmic drug therapy; likewise for cardiogenic shock, after application of dopamine and sodium nitroprusside cardiac cycle is improved then additional anti-arrhythmic drug should be applied. Application of anti-arrhythmic drug therapy can lead to normal life. |
