No association was observed between LVEF, VPC/h, and supraventricular premature contraction per hour over the 7-year follow-up period.<h4>Conclusions</h4>Over 7 years, women carrying pathogenic DMD gene variants have very little or no progression of cardiac findings (LVEF, fibrosis, and arrhythmias). Here, DMD is linked to Arrhythmia.
