Role and practical aspects of antiarrhythmic therapy in acute and chronic settings in children

Area of Science:

• Pediatric Cardiology
• Clinical Pharmacology
• Cardiac Electrophysiology

Background:

• Pediatric cardiac arrhythmias necessitate distinct diagnostic and therapeutic strategies compared to adults.
• Early intervention and individualized treatment are crucial for optimal outcomes in children.

Purpose of the Study:

• To review the application of antiarrhythmic drugs in pediatric acute and chronic conditions.
• To emphasize practical usage, safety considerations, and the integration of non-pharmacological therapies.

Main Methods:

• Review of current literature on antiarrhythmic drug therapy in pediatric patients.
• Analysis of drug choices for acute and chronic management of arrhythmias.
• Consideration of safety profiles and integration with other treatment modalities.

Main Results:

• Adenosine is the primary agent for acute supraventricular tachycardia treatment in children.
• Chronic management aims for recurrence-free periods via drug prophylaxis or catheter ablation.
• Beta-blockers should be selected cautiously, favoring cardioselective options in children with asthma-like symptoms; amiodarone is reserved for refractory cases.

Conclusions:

• Antiarrhythmic medications are fundamental in pediatric arrhythmia management.
• Safe and effective therapy relies on weight-adjusted dosing, vigilant monitoring, and age-appropriate drug selection.
• Successful treatment outcomes are achieved through multidisciplinary care and personalized strategies.
