2. Cardiac arrhythmias: origin, rate, rhythm, conduction velocity and sequence of heart activation are abnormally. Palpitations Dyspnea Fatigue Angina Headache Cardiac tachyarrhythmias may cause a large variety of signs and symptoms of which the most frequent are: While some could remain asymptomatic, others may evolve to cardiomyopathy with congestive heart failure, syncope and sudden death.

3. Supraventricular Tachycardia, Etienne Delacretaz, M.D. The New England Journal of Medicine 2006; 354:1039-1051 The most frequent tachyarrhythmias in the pediatric patient are Supraventricular tachycardias the majority of them are with structurally normal hearts Despite being more frequent there`s a high incidence of tachycardia resolution especially in the younger children and life-threatening events are less likely to occur than in those with congenital or acquired structural heart disease

4. Supraventricular tachycardias Rapid heart rhythms originating from the cardiac structures above or in the atrioventricular node.

5. the incidence of each type of arrhythmia the presence of tachycardia induced cardiomyopathy treatment required evolution by age groups To evaluate: This presentation focuses on supraventricular tachycardia in children with structurally normal hearts.

6. Study assessment  patient`s medical papers  ECG strips  treatment protocols Study: Retrospective Period: January 2005 – December 2013 Subjects: 67 pediatric patients Statistical analysis  GraphPad  Chi-Squared Test for Trend  Treated in the Pediatric Cardiology Department of Tirgu Mures

10. The only case was treated with a Beta-blocker PJRT

11.  Cured patients were statistically correlated with the onset in the younger age.  To obtain this correlation an extended contingency table was created in GraphPad.  Result: Chi-Squared Test for Trend p<0.0001

12.  The PSVT was the most frequently observed tachyarrhythmia.  From the permanent tachycardias cases there was a large group who developed tachycardia induced cardiomyopathy.  In the paroxysmal tachycardia group the pharmacologic therapy most used was based on beta-blockers while in those with permanent tachycardia the most used was Amiodarone.  A statistically significant group of pediatric patients had complete resolution of the tachycardia that was associated with the onset in the younger age.
