Diagnosis Of Early Cardiac Dysfunction in Patients With Idiopathic Frequent Monomorphic PVCs and effect of ablation and comparison between different sites of ablation

• Apply the speckle myocardial tracking technology to early diagnose dysfunction in patients with idiopathic frequent monomorphic PVCs
• Assessment of cardiac function before and after ablation and comparison before and after ablation and between sites of origin of the PVCs as diagnosed by the electrophysiologic and 3d mapping techniques that may be more confirmed by successful ablation whenever achieved

Inclusion Criteria:

• All patients of sample size admitted to the cardiology department of Assiut university hospital for ablation of idiopathic frequent monomorphic PVCs

Exclusion Criteria:

• Patients with well-known factors of cardiac dysfunctions, including high blood pressure (over 140/90 mmHg), hypertrophic cardiomyopathy, left ventricular hypertrophy, bundle branch block, severe valvular disease, complete heart block, and previous CABG.
