Exercise-induced asthma (EIA) after walking: a case report.

A case in which exercise-induced asthma (EIA) was provoked at an intensity of less than 100 beats/min is discussed. EIA was provoked by a 12-minute walk test. Earlier tests using walking on other subjects had not produced such a result. It is therefore vital to teach asthmatics to monitor their pulmonary response at regular intervals to avert serious attacks in activities of daily living.
