Interobserver variability of ventilatory anaerobic threshold in asymptomatic volunteers

摘要: The ventilatory anaerobic threshold (VO2@AT) has been used in preoperative risk assessment and rehabilitation for many years. Our aim was to determine the interobserver variability of AT using cardiopulmonary exercise (CPET) data from a large epidemiological study (SHIP, Study Health Pomerania). VO2@AT determined CPET 1,079 cross-sectional volunteers, according American Heart Association guidelines. determinations were compared between two experienced physicians, physicians qualified medical assistants, or assistants software-based algorithms. For first 522 sets, discussed discrepant readings reach consensus; remaining sets analyzed without consensus discussion. detectable 1,056 sets. recorded identical values 319 out of cases before discussion (61.1%; intraclass correlation coefficient [ICC]: 0.90; 95% confidence interval [CI]: 0.88–0.92) 700 overall (66.3%; ICC: 0.95; CI: 0.95–0.96), with an difference 0 ± 8% (95% limits agreement [LOA]: ±161 mL/min). − 2 ± 18% LOA: ±418 mL/min) physician and − 19 ± 24% − 22 ± 26% LOAs: ±719–806 mL/min) Experienced show high when determining asymptomatic volunteers. However, is lower, there substantial deviation determination This must be considered as decision tool.
