if it wasn't for the fact that both of my (younger) brothers have walked around with heart monitors on for a week and then went through a battery of tests only to be told that their arrhythmia was intermittent and non-specific (exercise and avoid caffeine)...and the fact that a few of my uncles have had their hearts shocked (because theirs stopped being intermittent), i'd probably be a little more worried. but, it's hereditary...you can't run from your genes.
however, the "stopping" thing is a little disconcerting...but it only happens during the worst part of tax season. what i need to do is get my business life straightened out so i can avoid that month of sleeplessness...that will probably, eventually kill me if i don't fix it.
