title: P-R segment depression: an early diagnostic feature in acute pericarditis: a telephone survey of UK accident and emergency departments.
abstract: P-R segment depression is an early ECG change in the evolution of acute pericarditis. This is widely recognized in the USA and appears in several major emergency medicine texts. A telephone survey was conducted to gain an overview of the knowledge of accident and emergency career doctors in the UK. We hope to use the results to highlight this potentially useful sign. One hundred accident and emergency departments, listed in the 1999 British Association for Accident and Emergency Medicine as seeing more than 40,000 new patients per year, were contacted in a telephone survey. The registrar, staff grade or consultant on call was asked to respond to a brief questionnaire. One hundred accident and emergency (A&E) specialist doctors were contacted--60 specialist registrars, 23 consultants and 17 staff grades. Of those questioned, 24% had a background in general medicine. The remainder had trained in surgery, A&E medicine or anaesthetics. None of the doctors questioned volunteered knowledge of P-R depression when asked an open question. Six doctors (6%) admitted, when prompted, to having previously heard of this sign. Knowledge of P-R segment depression is not widespread amongst UK A&E specialists. It is a potentially useful early electrocardiogram change in the evolution of acute pericarditis. Its recognition may aid diagnosis and prevent the inappropriate administration of thrombolytic therapy.
