Inter-Holter Reproducibility
Although a single Holter monitor per patient was used for derivation and
validation of the novel parameters, 25/69 patients (36%) from both
cohorts underwent multiple ambulatory ECGs prior to ablation. 44
supplemental Holter monitors (mean 1.8 per patient) were available to
test reproducibility. When using the CoV ≥ 0.7 parameter, supplemental
Holters agreed with the original prediction in 87.0%. When using the VE
< 50 parameter, agreement with the original prediction was
91.3%.
