The efficacy of ventricular pacing with device automaticity in paediatric patients


Tomaske, M; Harpes, P; Woy, N; Bauersfeld, U (2008). The efficacy of ventricular pacing with device automaticity in paediatric patients. Europace, 10(7):838-843.

Abstract

AIMS: To compare pacemaker reprogramming and re-intervention rates in children with AutoCapture (AC) and conventionally (Conv) programmed devices, and to assess reliability of device automaticity. METHODS AND RESULTS: Data of children with AC (group AC, n = 49) and conventionally programmed devices (group Conv, n = 41) were analysed. A total of 1106 outpatient visits and 147 Holter recordings were screened for device reprogramming and invasive re-intervention. At 2 and 5 years, freedom from reprogramming differed significantly between groups (AC: 63/35% vs. Conv: 13/4%; P < 0.0001), whereas freedom from re-intervention was not different (AC: 95/90% vs. Conv: 95/85%; P = 0.26). Mean yearly rate of reprogramming was lower in group AC (AC: 0.67 +/- 0.55 vs. Conv: 1.13 +/- 0.82; P = 0.005). Follow-up duration correlated with a decreasing number of reprogramming per year in group Conv (rho = -0.73, P < 0.001). No ventricular output reprogramming was required in group AC. Holter recordings required 0.07 +/- 0.13 reprogramming per year in group Conv, none in group AC (P < 0.001). Holter-detected lead dysfunction prompted re-intervention in one patient of each group. CONCLUSION: Estimated freedom from as well as total yearly rate of device reprogramming was favourable for AC-programmed devices. No difference was seen for the incidence of invasive re-interventions. AC ventricular output control was effective. Structured device follow-up and Holter recordings in specific patient groups remain mandatory for all devices in paediatric patients.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
