Prehospital misidentification of tachydysrhythmias: a report of five cases.

Identification and treatment of tachydysrhythmias is an important element of prehospital care. Five cases of prehospital misidentification of tachydysrhythmias are presented to highlight the challenges and pitfalls of field management. The literature is reviewed and discussed in light of new therapies and technology. Guidelines for patient subgroups potentially benefitting from on-line medical control and biotelemetry are explored.
