Clinical recovery day was defined as the point at which there was an absence of fever (\u226538\u00b0C) and no further need for vasoactive inotropes or respiratory support. The relationship between clinical recovery day and bradycardia and its implications for clinical course and prognosis was examined in this study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The study included 46 patients diagnosed with MIS\u2010C with a mean age of 10.06\u2009\u00b1\u20094.06\u2009years. The median time of clinical recovery was 4.0 (IQR\u2009=\u20091.0) days. Asymptomatic sinus bradycardia developed in 36 (78.3%) patients at a median duration of 4.0 (IQR\u2009=\u20092.0) days in the follow\u2010up period.
