Sensitivity and specificity of handheld one lead ECG detecting atrial fibrillation in an outpatient clinic setting.

AIMS: To validate the sensitivity and specificity of the Zenicor One handheld ECG device for detection of atrial fibrillation in an outpatient clinical setting. METHODS AND RESULTS: Patients attending outpatient clinics at Danderyd Hospital (n = 220) were examined with one lead handheld ECG immediately after standard care 12­lead ECG recording. Twelve recordings were excluded (atrial flutter or pacing) or missing. The recordings were dichotomously categorized as "atrial fibrillation" or "not atrial fibrillation" by two senior cardiologists. In cases of diverging interpretations, a third senior cardiologist had the deciding vote. Sensitivity and specificity in diagnosing atrial fibrillation was calculated with 12­lead ECG as gold standard. Sensitivity and specificity for diagnosis of atrial fibrillation with one lead handheld ECG and 12­lead ECG as gold standard was 98% and 99% respectively. CONCLUSION: In a health-care outpatient setting, Zenicor One handheld ECG had high sensitivity and specificity for detection of atrial fibrillation when compared with 12­lead ECG.

Identifying child functioning from an ICF-CY perspective: everyday life situations explored in measures of participation.

PURPOSE: This study was part of a larger work to develop an authentic measure consisting of code sets for self- or proxy-report of child participation. The aim was to identify common everyday life situations of children and youth based on measures of participation. METHOD: The study was descriptive in nature and involved several stages: systematic search of literature to find articles presenting measures for children and youth with disabilities, identifying measures in selected articles, linking items in included measures to the ICF-CY, analysing content in measures presented as performance and participation and identifying aggregations of ICF-CY codes across these measures. RESULTS: A large number of measures for children and youth with disabilities were identified but only 12 fulfilled the inclusion criteria. A slight distinction in content and age appropriateness appeared. Measures presented as performance covered all the ICF-CY Activities and Participation chapters, whereas measures presented as participation covered five of nine chapters. Three common everyday life situations emerged from the measures: Moving around, Engagement in play and Recreation and leisure. CONCLUSION: Only a small number of life situations for children and youth emerged from items in selected measures, thus, other sources are needed to identify more everyday life situations.
