AV conduction time changes with adrenaline and vagus/sympaticus tone and when I have sinus tachy my PQ is actually short. A Holter would usually capture AV blocks, as the heart rhythm is monitored also during sleep. Guess that's the best way to evaluate it.
Thank you. Someone posted in neurology (I think) and the only symptoms were extreme fatigue and chest pain. I know that was what my brother had for years with his heart block which went undiagnosed but this person said she had an ekg and an echo I think so I was wondering if it could come and go (be missed on the ekg)?
Comes and goes. Often worse during rest, especially at sleep, where first degree and second degree type 1 are considered normal, according to the articles I've read about it. Often worse in athletes. A resting EKG can give a hint anyway, if the PQ time is borderline long you are more likely to get it.
