‡ Potassium is the venous-blood-gas value. The simultaneous serum potassium was 4.9 mmol/L but was flagged as affected by haemolysis and was not used for causal assessment of the presenting AV block. BUN: blood urea nitrogen; CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; CRP: C-reactive protein; eGFR: estimated glomerular filtration rate; hs-Troponin T: high-sensitivity troponin T; NT-proBNP: N-terminal pro-B-type natriuretic peptide; WBC: white blood cell count.
