This study was done in patients with sleep apnea which is a condition that is usually found in obese people who transiently close their airway during sleep due to excess tissue in the throat. Vagal tone is usually at the highest level during sleep and it's not uncommon to have pauses like you mentioned. The significance of the pauses seen on your Holter Monitor is unclear, but I doubt that these pauses are anything to worry about. Mobitz I AV block is considered to be a benign rhythm disorder, but the significance of this and the pauses found on your Holter monitor will have to be determined by your own physician. I hope this information is useful.
