Frequent PVCs-defined as a burden \\>5% on two separate 24-hour Holter recordings-are increasingly recognized as a cause of reversible systolic dysfunction in patients without structural heart disease.\n\nParticipants undergo a comprehensive baseline evaluation including echocardiography, occasionally cardiac MRI, and coronary angiography or equivalent testing to confirm the absence of structural abnormalities. Patients are enrolled only if they are ineligible or unwilling to undergo catheter ablation, and have no contraindications to flecainide.\n\nFlecainide therapy is initiated at a starting dose of 100 mg\u002Fday and titrated up to 200 mg\u002Fday, guided by ECG findings, symptom response, and QRS duration. Regular follow-up occurs at three-month intervals over three years, with periodic 24-hour Holter monitoring and assessment of symptoms, LVEF, and adverse events.\n\nThe primary outcome is the reduction in PVC burden. Secondary outcomes include improvement in LVEF, symptom relief (measured by structured questionnaires), adverse effects, and long-term treatment adherence. The study aims to generate real-world data on the non-invasive management of PVCs with flecainide and explore its role as an alternative to ablation in carefully selected patients.",[29,27,28,62,63,64,65,66],"Arrhythmia Ventricular","Ventricular Dysfunction, Left","Ventricular Dysfunction","Cardiomyopathies, Secondary","Cardiomyopathies",[68,69,54,70,31,71,72,73],"Flecainide","Sanocard","PVC induced CMP","Premature Ventricular Contraction","Outflow Tract PVC","NonOutflow Tract PVC","RECRUITING","2025-06-27",{"date":77,"type":39},"2025-07-02",{"date":79,"type":39},"2024-04-26",{"date":81,"type":21},"2027-12-01",{"name":83,"class":46},"University of Athens",6]
