However, there are little data regarding the prognostic role of fQRS in peripartum cardiomyopathy (PPCM) patients. We aimed to investigate the effect of fQRS on predicting left ventricular (LV) nonrecovery in patients with peripartum cardiomyopathy (PPCM).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ninety patients (mean age: 34.7\u00a0\u00b1\u00a06.5\u00a0years) with the diagnosis of PPCM were analyzed retrospectively. The median follow\u2010up period of was 67.0 (12.0\u2013192.0) months. Fragmented QRS was defined as the presence of various RSR\u2019 patterns (QRS duration\u00a0&lt;\u00a0120\u00a0ms) with or without Q wave, which include an additional R wave (R\u2019 prime) or notching of the R wave or S wave, or the presence of more than one R' (fragmentation) without typical bundle branch block.
