ECG in asthmatics with acute severe exacerbation may reveal [[sinus tachycardia]] and a right heart strain pattern. However, the administration of a [[Bronchodilator#Short-acting β2-agonists|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 [[Bronchodilator#Theophylline|theophylline]] toxicity. | |||

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.
