PACs or 2nd degree heart block

Hi everyone,, I just have a question and wondering if anyone else has ever been in a similar position. My son, who is only 12 months has bradycardia. Normally for his age range his pulse should be between 100-120bpm. When active his pulse is only about 70, when he sleeps its always in the 40s and has dipped into the 30s. The first cardiologist said based on his hospital visit and 24 hour halter monitor, that he had a second degree block and would need  pacemaker.Then when we met with the electrophysiologist, he said that he thinks no block but just premature beats(PACs). He's currently on medication for the premature beats but none seem to be working. We are looking into a second opinion only because we went from one extreme to the other. Any thoughts or anyone been in a similar situation? thank you so much!

I'm afraid your question is extremely difficult to answer on this board. The fact that two cardiologists disagree should tell how difficult this is.

If the PACs origin close to the sinus node and are blocked (not conducted to the ventricles) they can look exactly like second degree AV block. If they are constantly present (bigeminy pattern) they can look exactly like 2:1 block.

Only an EP study can tell the difference for sure.

Yes I've been reading and talking to people about how difficult it is. Thats why i was wondering if anyone else has had anything similar :( The electrophysiologist said that he's too young for an EP study.
