For other examples, see general assumptions. Additional examples of result data: "SINUS BRADYCARDIA", "ATRIAL FLUTTER", "ATRIAL FIBRILLATION". Test results are in two separate codelists, one for tests based on regular 10-second ECGs (EGSTRESC) and one for tests based on Holter monitoring (HESTRESC). | Exp |
