Clinical features and antiarrhythmic therapy in patients with catecholaminergic polymorphic ventricular tachycardia

Aims . To evaluate the long-term efficacy of antiarrhythmic therapy in patients with catecholaminergic polymorphic ventricular tachycardia (CPVT). Methods CPVT was diagnosed 11 between ages 3-12 years a minimum follow-up 10 years. The data analyzed obtained from existing medical records that included symptoms, family screenings, treadmill tests, electrocardiography, echocardiography, implanted cardioverter-defibrillator (ICD), and treatments. Results Cardiac events were registered 75% on beta-blocker therapy. Supraventricular arrhythmias such as atrial atrioventicular nodal tachycardia, fibrillation flutter detected using various ECG diagnostic methods all patients, which is significantly higher than reported similar studies. A combination anti-arrhythmic treatment reduced number cardiac by 50% compared to only treatment. Conclusion Multiple supraventricular have high prevalence can trigger arrhythmia. Combined effective because it prevents CPVT. improves prognosis may help avoid or postpone ICD implantation.
