Sounds like mixed findings, some are normal and some are not, but of course, your/his doctor should interpret it.
You can ignore the "ventricular arrhythmias" as those are supraventricular arrhythmias conducted with so-called aberrancy, which often happens. He does have a lot of premature atrial beats and runs. Which are normal and common, but he seems to have a lot of them. They can be experienced as palpitations, but they are usually not dangerous.
His heart rate is fairly slow and the AV block at night is fairly common in well-trained individuals, again, it may be normal and it may not. Make sure he does not suffer from atrial fibrillation, though. The report is a bit unclear regarding that.
Did he have symptoms during the test? If so, when? It's important for his doctor to know. AV block is, as mentioned, fairly normal at night but not during daytime. If he has events of AV block at daytime, this may be to blame for the syncopes.
Also, the report doesn't specify how rapid his atrial runs were. If they are very rapid, that may also be to blame for the syncopes. This is important to determine as treatment is very different.
is_something_wrong, I wonder if the AV block is in reaction to the atrial ectopics?
Also I think they already said the 2nd degree AV block is Type 1. To diagnose type 1, atrial rhythm has to be regular, which it doesn't appear to be but we'd have to see the strip. If the AV block is occurring during irregular atrial rhythm, there might be other causes why the P waves are being blocked.
It might be. At least that happened on my Holter.
Heart rate was slow at night, AV node had long refractory time, a PAC hit and was blocked. Looked funny, but it was actually completely normal.
yep, that's what I was thinking.
thanks for your thoughts, The holter was done on a normal school day,he rarely notices palpatations if has any .... the next day he had a repeat stress test, it was classed as within normal limits, although he couldn't finish it because of fatigue.
The block apparently came and went all day long, he has had many ECG's but it has only been caught on this holter.
Can you tell me what number represented the premature atrial beats?? could this be anything to do with early repolarization?? and do you think a RR 2130ms is normal
Monday I will chase up an appointment at the university hospital.
RR of 2130 msec means 2.13 seconds between one heart beat and the next. Which means a heart rate of approx. 30. The atrial beats are the sum of premature atrials and those noted as ventricular (which they are not)
Do you know if it is common to have runs of atrial fibrulation, with episodes of bradycardia???
It's not entirely uncommon, but most people with bradycardia do not have atrial fibrillation.
is it possible this result, COULD be sick sinus syndrome or tachy/brady???? even though he is only 15yrs, (SSS is usually seen in older people)
Absolutely possible. SSS is not only seen in older people. But again, it's hard to tell from the numbers.
