About this study

The aim of the proposed study is to determine if individuals with excessive supraventricular ectopic activity (ESVEA) on Holter recording should be subjected to prolonged screening with Event loop recorder in order to detect previously undiagnosed Atrial fibrillation / flutter. Other biomarkers such as plasma biomarkers, high-end echocardiography and assessment of blood pressure and atrial stiffness will be studied and compared in ESVEA and control group as well as progression of atrial cardiomyopathy in ESVEA patients.
