Diaphragmatic flutter emulating recalcitrant asthma.

Diaphragmatic flutter is a rare phenomenon characterized by high-frequency, pulsatile contractions of the thorax and abdominal wall associated with breathlessness. We describe the case of a patient previously treated for status asthmaticus who had physical signs of diaphragmatic flutter. Respiratory inductive plethysmography confirmed the diagnosis, simplifying medical management.
