I've got a question for the forum.
Recently a good friend had a series of sinsus arrests (sinus node dysfunction) resulting from a vaso vagal synchronicity problem . He is a mid-40's trained non-elite athlete (skier, runner) who is in very good shape (has been so for 10 years) and recently set lifetime running personal bests. After a multitude of tests, the doctors could not isolate the specific cause of the issue, bringing it to unknown cardiac origin. All incidents occured while sitting or standing, never during exercise and not necessarily related to recent heavy exercise.
Treatment (after 10 days in hospital) was a choice between a pacemaker (which apparently only works in a portion of cases like this) and ensuring that he stays well hydrated with a saliine solution. The second was chosen for the time being. No incidents have occured since release.
No genetic issues whatsoever related to cardiac problems before age 90. He (and others in the family) have a history of leg cramps during exercise and high levels of sweating (one sibling has ended up in the hospital/medical tent a few times from excessive electrolyte loss after exercise). No clinic related issues or tendencies either.
Does anyone have any understanding or information about this form of sinus node dysfunction, particularly as it relates to trained athletes? Any help or links would be appreciated.
Thanks.
