Mobitz Type I

A year ago I was diagnosed with Mobitz Type I AV Node block. This was
during a medical for a private pilots license. After a lot of indecision
I was certified to fly, caveat that I have a yearly holter monitor that
does not show more than 1 consecutive dropped P-wave. Incidently I know
I have had this condition for most of my life (37 yo) - it has never been
a problem - I am asymptomatic.
Needless to say my last holter showed 3 consecutive dropped p-waves giving
a pause of 3.7 seconds.
However this occured at 5am (definitely asleep!!!) at a heart rate of
70bpm. This was unusually high - the rate was mostly less than 40bpm while
sleeping. Also on the strip there was a large amount of noise(?) which
the p-waves were only just distinguishable above only during that pause.
Has there been any research carried out on the influence of sleep patterns
on the AV node/Vagal Tone. ie. How relevant is monitoring during sleep?
