Although these arrhythmias are usually secondary to structural heart diseases that are commonly associated with <jats:styled-content style=\"fixed-case\">CKD<\/jats:styled-content>, a significant proportion of cases with sudden cardiac death have no obvious structural heart disease.

Inclusion criteria selected patients who had 12\u2010lead surface electrocardiography (<jats:styled-content style=\"fixed-case\">ECG<\/jats:styled-content>), renal function tests within 24 hours, and transthoracic echocardiography within 6 months.
