Slight borderline qtc in ECG results?

I'm a 22 year old male, suffered from very infrequent and sporadic heart palpitations (PVC's) since I was 14/15- I've never blacked out and only once felt light headed from a run of 4/5 PVC's last week. This caused me to go the GP who booked me in for an ECG which returned the results of 1 borderline qtc, meaning I have been referred to a cardiologist. Should I be concerned? Is Long QT syndrome the only diagnosis it could be, what are other explanations? My family history is inconclusive (my granddad has heart problems but only in very old age, and I had a great uncle who died suddenly, but this is an insignificant link)

There are lots of other explanations for the PVCs.

They thought mine were related to something called ARVD.  I had all these risk factors for it.  I had to have a cardiac MRI to rule it in/out.  I was very scared.  Turns out I didn't have it.  That's when we all gave up trying to find an answer and I just moved on.

best advice I can give is stick with the appointment and see what they say.  You're going to have to walk through the process to rule things in/out.

thanks for getting back.

I know, i'm sure there are other explanations for the PVC's, but i've never had an ECG thats come back abnormal, just wondering if you know if 'borderline prolonged qtc's' are anything to worry about? Thats the thing thats getting to me- if its just a precaution then I'm ok with that.

People get variations in EKGs all the time.  There was someone who was on here recently that had 3 EKGs in several days on different machines and the findings were all different.

EKGs are almost always a gateway for more definitive look to see if there's something.

Sorry I can't set your mind at ease.  You need to get more tests done to figure it out.

I should also say that I had a 24 hr ECG done 2 years ago which picked up nothing significant so I don't know why this supposedly simpler baseline ECG has picked up a slight prolonged QTc..

My friend whom is a paramedic said prolonged qt is not serious and nothing to be concerned with,there is no need for a cardiologist for that
