Аннотация
Supraventricular tachycardia (SVT) following fenoterol inhalation in metered-dose inhaler (MDI) has never been reported. We report two cases of SVT after fenoterol inhalation in MDI. Case one was a 4-year-old boy who had asthma since early childhood. Paroxysmal supraventricular tachycardia (PSVT) was found after fenoterol inhalation (MDI), which returned to normal sinus rhythm following adenosine injection. The other one was a 9-year-old male who also had asthma since early childhood. He suffered from attacks of PSVT four times after fenoterol inhalation within one year. After verapamil injection and vagal maneuvers, PSVT was converted to normal sinus rhythm. There were no other episodes of SVT after discontinuing usage of fenoterol inhalation for 2 years in the follow-up. We report these two cases to remind pediatricians that cardiac arrhythmias should be evaluated following fenoterol inhalation (MDI).
