Second degree atrioventricular (Mobitz) type-1 heart block. Minnesota (MN) code 6-2-3. 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.

Second degree atrioventricular (Mobitz) type-2 heart block. Minnesota (MN) code 6-2-1. 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.

Minnesota (MN) code 6-2-2. 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.

Participant taking SECOND GENERATION SULFONYLUREAS within two weeks of the Sleep Heart Health Study Visit Two (SHHS2) visit. All medications were recorded during the interview, and medication information was later categorized by physician review.

Average resting diastolic blood pressure of two measurements collected from the upper arm in a single clinic visit. When more than two measurements were collected, the average was calculated using the second and third measurements. In cases where either of the measurements was missing, the average was calculated discarding the missing value. Harmonized by the NSRR team to align with TOPMed and BioDataCatalyst standards.
