rhythm under Clinical Data/Diagnostic Studies/Electrocardiogram in CFS variables

nodal under Clinical Data/Diagnostic Studies/Electrocardiogram in SHHS variables

Abnormal heart rhythm resulting from impulses from the atrioventricular node. Minnesota (MN) code 8-4-1. Data derived from standard resting 12-lead electrocardiogram (ECG) with the participant supine. Records were interpreted and Minnesota (MN) codes were provided by clinical cardiologists.
