Assessment of Intrathoracic Impedance Algorithm in the Pediatric and Adult Congenital Population

Abstract

The algorithm sensitivity for pediatric DCM, HCM, CHD, and adult CHD was equivalent to the general adult population. Further studies are warranted to assess whether inaccuracy in prediction is secondary to the algorithm or to differences in the clinical response of pediatric/CHD patients.

“…We read with interest the "Assessment of intrathoracic impedance algorithm in the pediatric and adult congenital heart population" by Silva et al, 1 particularly because the authors contrast our own paper on the subject. 2 Silva et al conclude, in their Medtronic-funded study, that Optivol (Medtronic Inc., Minneapolis, MN, USA)-an intrathoracic impedance monitoring feature in cardiac devices-has considerably greater utility than found in our own analysis.…”
