Introduction
Overview
Overview
ECG in asthmatics with acute severe exacerbation may reveal sinus tachycardia and a right heart strain pattern. However, the administration of a β2-agonist may relieve symptoms and hence result in a paradoxical decrease in heart rate. The presence of supraventricular tachycardia should raise a suspicion of theophylline toxicity.[1]
