9 Possible Causes for Onset of Symptoms in the Fourth to Sixth Decade of Life, Progressive Decrease in Atrial Voltage

  • Atrial Standstill

    An asymptomatic patient with cardiomegaly caused by isolated right atrial standstill is reported. The right atrium showed no evidence of contraction on pressure records or angiographically, while the left atrium functioned normally.[ncbi.nlm.nih.gov]

  • Restless Legs Syndrome

    Although one third of patients are affected before the age of 20 years, clinical presentation typically occurs between the fourth and sixth decades of life, when sensory symptoms[doi.org] […] of disease, sensory symptoms are mild and punctuated by asymptomatic periods of variable duration.[doi.org] […] age-dependent expressivity; the influences of anemia, uremia, diabetes, and peripheral neuropathy; and possibly the modulation of phenotype by body iron stores. 18 At the onset[doi.org]

    Onset of symptoms can be described as bimodal, with one peak in the third to fourth decade of life (early onset) and another distinct peak in the sixth decade of life (late[journals.lww.com]
