I have had an ecg, and i got 17 single supraventricular extrasystoles in 24 hours. (i did not have ventricular extrasystoles) is this a scary high amount? or is it very normal?

You demonstrated only mild,almost trivial supraventricular( atrial or nodal) irritability. Was it scattered throughout the 24 hours,related to exertion,during sleep? Did youhave palpitations during those premature beats? Have you had days when you had very more palpitations? Do you need more monitoring? Have heart murmur or mitral valve prolapse by echocardiogram? Caffeine or alcohol use effect?
