What is Atrial run?

Ectopic Atrial Tachycardia (EAT) is a relatively rare arrhythmia in the pediatric population. It is defined by a run of more than 3 premature atrial contractions together. In EAT, the arrhythmia tends to increase in rate over a period of time and then slows down gradually to a normal rhythm. Ectopic Atrial Tachycardia (EAT) is mostly encountered in patients with stucturally normal hearts however, occasionally physicians do observe this type of disorder in children following surgery for congenital heart defects. Current reports suggest that EAT occurs in approximately 1 in 10,000 children

What you are referring to is a run of atrial ectopic beats. I am guessing that because they are using the word run, they are referring to what we call supraventricluar tachycardia or SVT.This is where one of the hearts natural “backup” pacemakers fires off a number of beats very quickly. With some people this lasts only a few seconds, but can last up to hours. The concern with this condition is that if the heart is beating too quickly for too long, it will not serve as an effective pump to get oxygen to your tissues (esp. brain and heart). This is why you should call 911 immediately if you are getting symptoms of light headedness, severe shortness of breath, or chest pain with your rapid heart beat/palpitations (Im guessing that these [the palpitations/rapid heart rate] are your symptoms judging from the findings).If the run were especially concerning, the technician on the other end of the phone would have contacted your physician immediately. Go ahead and call your doctors office in the morning and find out exactly what was on the monitor and what it means for you.BECAUSE I CANNOT SEE THE ECG STRIP, I CANNOT GUARANTEE THAT THE INFORMATION ABOVE APPLIES DIRECTLY TO YOUR SITUATION.
