Abstract:
The Long QT syndrome (LQTS) is a rare disorder in which patients are prone to life threatening ventricular arrhythmia and is a leading cause of sudden death in childhood. Asthma is common and its management in those with LQTS presents a number of potential difficulties. The mainstay of therapy in LQTS is beta-blockade, which may worsen symptoms of asthma. Conversely, beta-agonist therapy is the mainstay of asthma management; which, in those with LQTS, may provoke ventricular arrhythmias. We review available data regarding the management of coexistent LQTS and asthma, and provide a summary of the necessary considerations in managing these patients.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
