| Summary: | Atrial fibrillation (AF) has been associated with lung diseases like pneumonia and chronic obstructive pulmonary disease but has only infrequently been associated with inhalational lung injury. We report two cases of resistant AF, which developed in young healthy manual laborers shortly after inhalational lung injury due to massive quantity of pesticides and anhydrous ammonia, respectively. They had no evidence of valvular or structural heart disease and did not have any previous medical problems. The AF was resistant to antiarrhythmic drugs and required pulmonary vein isolation in first patient and possibly the second patient who is currently being evaluated for this procedure. These arrhythmias may reflect direct myocardial injury during and after exposure. Alternatively, multiple mechanisms can cause atrial fibrillation in lung diseases, including hypoxemia, acidemia, inflammatory mediators, and structural changes in the atria and ventricle, and these could lead to AF in inhalational lung injury cases. AF needs to be excluded when patients present with palpitations after inhalational lung injury, especially since, if unrecognized, AF may lead to complications, like thromboembolic phenomenon and tachycardiomyopathy. |
