Wolff-Parkinson-White (WPW) syndrome is a relatively common cardiac disorder caused by accessory conduction fibers in the heart's electrical system. This can lead to arrhythmic symptoms and complications with potentially life-threatening consequences for affected individuals, potentially precluding their suitability for working at heights from an occupational health perspective. However, the condition can be successfully treated with thorough diagnostics and targeted ablation of the underlying cardiac muscle fibers, restoring or maintaining fitness for working at heights. This presentation will provide fundamental information about the disease and illustrate, using a case study from our own practice, that assessing fall risk and evaluating fitness for working at heights can be challenging.
