Summarizing our results, we suggested ECG patterns representative of the different AFD stages as assessed by the increases in LV thickness over time (Central Figure). Patients from group A showed mostly a normal ECG (77%) or minor anomalies like LVH criteria (8%) and delta wave\/slurred QR onset\u2009+\u2009borderline PR (8%). Differently, patients from groups B and C exhibited more heterogeneous ECG patterns: LVH (17%; 7% respectively); LVH\u2009+\u2009LV strain (9%; 17%); incomplete RBBB\u2009+\u2009repolarization abnormalities (8%; 9%), more frequently associated with LVH criteria in group C than B (8%; 15%). Finally, patients from group D showed very peculiar ECG patterns, represented by complete RBBB\u2009+\u2009LVH and repolarization abnormalities (40%), sometimes associated with QRS fragmentation (13%).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>ECG is a sensitive tool for early identification and long-term monitoring of cardiac involvement in patients with AFD, providing \u201cinstantaneous pictures\u201d along the natural history of AFD.
