Natural History of Cardiac Rhythm and Conduction Disorders in Patients With Fabry Disease Evaluated by Long-Term Implantable Holter ECG
The main objective is to assess the occurrence of cardiac arrhythmias and conduction disorders during a three-year follow-up using implantable Holter ECG monitoring in 40 patients with Fabry disease. The secondary objectives are to analyze the correlations of these anomalies with changes in cardiac MRI and echocardiographic parameters as biological parameters and overall severity of the disease assessed by MSSI.
