Collapse

Synonym(s): Weakness

Contributor(s): Kyle Braund, Kate Murphy

Introduction

  • Cause: it can be very difficult when first presented with an animal that has had 'a funny turn' to establish the etiology.
  • Diagnosis:
    • It is vital to take a complete history from the owners and if the episodes are recurrent to ask them to collect further information during subsequent episodes, eg heart rate, mucous membrane color, responsiveness.
    • Unless episodes are occurring sufficiently frequently it may be impossible to see one yourself.
    • Ask the owners to video an episode if it occurs at home and, if not possible, ensure they give you a very detailed description of the event and that you listen with an open mind.
    • Collapse is a diagnostic challenge and many tests will yield negative results and thus achieving a definitive diagnosis may be impossible.
    • Examination of the patient as close to an episode as possible, ideally during, or shortly after an episode, may be most useful.
