Throughout the past decade, there were no straightforward recommendations regarding the management of asymptomatic high-burden Premature ventricular complexes (PVCs) in structurally normal heart extending from the European Society of Cardiology (ESC) guidelines of management of ventricular arrhythmias in 2014, passing by the American Heart Association (AHA), American College of Cardiology (ACC), and Heart Rhythm Association (HRA) guidelines 2017, and reaching to the recent ESC guidelines in 2022 that declared overtly that there is a gap of evidence regarding management of asymptomatic high burden PVCs in structurally normal heart. The goal of this clinical trial is to know if other imaging modalities rather than the conventional Two-dimension (2D) echocardiography can guide the treatment strategy of high-burden idiopathic premature ventricular complexes (PVCs). In our clinical trial, we used 2D speckle tracking of left ventricular (LV) global longitudinal strain (GLS) as an indicator for subtle LV systolic dysfunction in patients with structurally normal heart by conventional echocardiography. The main questions the trial aims to answer are: * Is radiofrequency catheter ablation an effective method in the treatment of early subtle myocardial dysfunction in patients with normal left ventricle ejection fraction (LVEF) and internal dimensions guided by 2D STE of GLS before progression into overt LV systolic dysfunction? * Is there a correlation between radiofrequency catheter ablation of asymptomatic frequent idiopathic PVCs and improvement of patient functional capacity as an indicator for subconscious adaptation? * Is there a correlation between PVC burden and the degree of impairment of GLS? Researchers will compare group A (control group) and group B (ablation group) to see if there is a significant difference between them regarding global longitudinal strain. Participants will be randomized into two groups each containing 20 patients. Group A (Control group): will be subjected to the standard of care being regular follow-up of symptom status and left ventricular ejection fraction (LVEF) Group B (ablation group): will be scheduled for PVC ablation.
